Re: OS Upgrade Version 2 using NSO

imrbaig — Wed, 02 Jun 2021 17:04:10 GMT

Thanks randreetta for your comments. Basically this package provides framework which can be leveraged so network engineers do not need to have any programming skills to perform device upgrades.

Manual device os-upgrade process needs MOP creation & validation (based on existing os on device and recommended future os etc.). Upgrade MOP includes steps(pre-check/post-check/upgrade process, multi path upgrade if device on older version, HA etc) that needs to be taken to reach target os version. This package also provides sample MOPs which can be extended without any programming skills. Basically this package help automate the upgrade process for an organization.

Re: How to Configure LSA in Layman's Terms

swilsons — Wed, 02 Jun 2021 09:23:22 GMT

Hi,

I'm trying to compile the RFS yang model for CFS, but getting into issues. Could someone take a look at it?

As suggested I've replaced all the leafref to string in the service model yand, but there were issues with missing tailf modules. After adding those there is an issue with circular reference.

Replaced “leafref” with string in all the service yang modules.

[root@upper yang]# grep -r "leafref" .

Re: OS Upgrade Version 2 using NSO

randreetta — Mon, 31 May 2021 19:35:12 GMT

such a tool requires a lot of work under the hood, unless you just provide a 'skeleton' of things to be called, for pre-checks, post-checks, and upgrade processes that needs to be developed by the customer. Something that changes and needs to be maintained during time (add some other costs). That's the common base for all NSO services: all the added value is provided by the java/python scripts, thus by programmers.

'Easy automation' and costs savings are just for marketing people, reality is much different.

How to find agentCount for single Attribute using cisco attribute API

sindhureddy — Tue, 25 May 2021 08:11:24 GMT

I want to find out how many agents are configured for an attribute. I have followed all the steps which are provided by the Cisco UCCE 11.6 API guide but I could not get the count. Is it possible to get a count of agents or not?

Archive Webex Space messages

Dirk-Jan Uittenbogaard — Tue, 18 May 2021 16:04:07 GMT

Lately I have received a few requests from people asking if it was possible to Archive a Webex Message
Space as in "download all messages".
Interesting.

You can download all messages using the messages API but that leaves you with a pile of unreadable JSON data.

Therefore I wrote a Python script that downloads space messages and turns it into an HTML file.
This is a single HTML file that looks just like the Webex Message client.

Features

Archive all messages in a space
Find space ID with built in search function
Deal with threaded messages
Download space images, files or both
All files are organized: \spacenamefolder with subfolders for \files, \images, \avatars
Export space data to JSON or TXT file
Restrict messages by number of messages or number of days
Display: messages grouped per month
Display: show full user names
Display: show (linked or downloaded) user avatars
Display: attached file-names + size
Display: "@mentions" in a different color
Display: quoted or formatted text
Display: external users in different color (users with other domain)
Display: images in popup when clicked
Print: just like it appears on the screen

Video

Use case

Potential use-cases:

For regulatory reasons (export & store content)
Make the full contents of a space easier to read & search (in 1 single file)
Share content & discussions with non Webex Message users or members
Sharing Q&A's

Code, Installation & Configuration

This is all explained on the Github page: see https://github.com/DJF3/Webex-Message-space-archiver

New: Webex Space Tab API

Dirk-Jan Uittenbogaard — Tue, 18 May 2021 14:57:06 GMT

On May 10th 2021 a new API component was added: SPACE Tabs!

We call them ROOM tabs to be consistent with the room (space) API. Room Tabs represent an always available tab that is added as a tab in the space. It is configured with a content url. Just like in the Webex app, you must be a member of the room in order to list its Room Tabs.

What to use these for?

In your team space, add a tab with your team intranet page.
In a finance space, add a tab with a specific Smartsheet
For an event space: add tabs for event project management tools
For file access: add box.com tab to see certain files in a space
In brainstorming spaces, add a Miro tab

The same applies to any other tool like Trello, Youtube, etc.

NOTE: when a login is required for pages in space tabs, you do have to login. Tools that use Single Sign On will make life easier.

TIP: when you click a tab one more time a menu appears with the following options:

TIP: you can also move the space tab into a separate window by clicking the icon marked here:

Room Tab API call

When using the room tabs API to list all tabs you can expect something like this:

{
  "items": [
    {
      "id": "Y2lzY29zcGFMzQ1NWQ1ZDExZWYzOmNkZTGQtMTFlNS1iYTljLTdiNjU1NmQyMjA3Yg",
      "roomId": "Y2lzY29zcGFyJPT00vYJjZWIxYWQtNDNmMS0zYjU4LTkxNDctZjE0YmIwYzRkMTU0",
      "roomType": "group",
      "displayName": "Project Management HomePage",
      "contentUrl": "https://internal.cisco.com/projectmanager/team/233210119",
      "creatorId": "Y2lzY29L3VzL1BFT1BMRS9mNWIzNjE4Ny1jOGRkLTQ3MOGIyZi1mOWM0NDdmMjkwNDY",
      "created": "2021-05-18T26:14:16"
    }
  ]
}

Where:

id          = the space tab ID
roomId      = space that the tab is visible in
DisplayName = Title of the tab
contentUrl  = Tab content source URL
creatorId   = userId of the person who added the tab
created     = date & time

When creating a space tab, the following items are required:

roomId
contentUrl
displayName

Details: https://developer.webex.com/docs/api/v1/room-tabs

Besides creating space t....ehh room tabs you can also remove/update/read them:

Developer Days Call for Speaker is now open!

Nicklas Wagerth — Fri, 30 Apr 2021 07:08:21 GMT

All,

We are excited to announce that our call for speakers for our upcoming Developer Days events is open!

Automation is a journey in itself and no two journeys are alike. Planning and preparation are a must for any major project. Having an open mind to unforeseen events, daring to accept help from others and collaboration makes the trip a much more enjoyable experience.

We are planning four Developer Days events over the next 12 months, and are now looking for presenters who would like to share their experiences. An important segment at our events is to present real-world stories and focus on success factors. Of course, we also talk about pitfalls and how to avoid them but the solution and the success is our focus.

We want to know what challenges you faced and how you solved them. What made your solution special and how did you get there? How does NSO fit into your architecture and what features helped you most? What features would have helped you more?

Thank you for your continued support.

//NSO Team

Webex Message CARD school

Dirk-Jan Uittenbogaard — Fri, 16 Apr 2021 11:55:46 GMT

In a previous article I talked about the Cards & Buttons functionality of Webex Message. It's great to send nicely formatted or interactive messages.

What if you want to learn about Cards? There is a bot that teaches you all about Cards using...

...CARDS!

A lovely and interactive way to learn. How does it work? As mentioned on the Cardschool App hub page, just add cardSchool@webex.bot to a 1:1 space and say hello. The bot will then guide you through the world of cards. (BTW, you can also add the bot to a group space)

When designing your own cards please look at the CardSampler. An online tool where you can design your card and it spits out the JSON needed for that card.

Please try it and let me know what you think!

Webex Cards using webexteamssdk library

Dirk-Jan Uittenbogaard — Tue, 13 Apr 2021 10:33:37 GMT

The Python library "webexteamssdk" is great but there's one part of this library that "may need better documentation". This is the ability to create cards & buttons.

Here's a card example:

How is this card setup? What components are used? The following image visualizes the underlying architecture:

That's why I found out what's wrong with the code and ended up with a working example that I want to share with you.

Webex Message oAuth Integration

Dirk-Jan Uittenbogaard — Wed, 07 Apr 2021 11:19:48 GMT

(using Python and the Flask Library)

An oAuth integration allows you to have an application "do stuff on your behalf".

This is a topic that can be quite complex to understand. For that reason I created this Python code to make it as easy as possible to understand.

What happens in when you run this code?

Step 1

First you open the application that can only say "hello world". Click the authenticate link.

Step 2

After successful authentication on the Webex platform (with or without SSO integration), you have to confirm that application XYZ is allowed to do things on your behalf.

Step 3

Now the application can, on your behalf, get your details (name, email address, etc).

How does oAuth work?

Here's a single slide that I created as part of an extensive oAuth presentation. (Let me know if I should publish that presentation on Youtube!)

Now go ahead and look at the instructions / code and try to make it work.

Details, code & setup on Github

Add Logos/Text To Your Virtual Background?

Dirk-Jan Uittenbogaard — Fri, 16 Apr 2021 14:38:27 GMT

It may be easier than you think.

After some customer requests I started writing code in Python. A few days later the script was ready.

What can it do?

ADD LOGO or image to your virtual background (using a domain/email address/URL/local-file)
ADD TEXT to your virtual background
CLEAR the above from your virtual background
SWITCH between user-defined virtual backgrounds
CHANGE the image of one of the 3 user-defined virtual background slots (based on a local file or URL)
AUTOMATIC logo insertion based on call participant email domains

What next?

Re: How to make sure IP is unique in a simple service to configure IP

erdemk — Wed, 24 Mar 2021 20:41:33 GMT

Hello Chandra,

Answer to your question is yes. You will need to model the interface and populate the interface data within NSO.

If this is the question, you can address other parts of your yang model to address for a contraint with must statement, ie. in your case other than "leaf ip_address".

Regards.

Re: How to make sure IP is unique in a simple service to configure IP

Chandra L — Wed, 24 Mar 2021 16:58:06 GMT

Thank you vleijon and erdemk for the information about "unique" option within the yang leaf, I will read this document to understand better on how to use this for my requirement.

For now I am just using the lab as I have it and instructing the users to be cautions about the duplicate IP, as I am running short of time, I will explore these options later on.

Re: How to make sure IP is unique in a simple service to configure IP

Chandra L — Wed, 24 Mar 2021 16:54:34 GMT

Thank you erdemk for your suggestions, as I understand with option 1 you mentioned as below, NSO will check if the IP is already within colour service, if so "ip address already in use". But if the IP address is not used in colour service, but in use on an interface on the router, will this logic still work?

must "count(../../colour[name != current()/../name]/ip_address = current()) = 0" {
error-message "ip address already in use.";

Re: How to make sure IP is unique in a simple service to configure IP

vleijon — Wed, 24 Mar 2021 14:28:57 GMT

I also want to mention tailf:unique-selector 5he standard YANG statement 'unique' can be used to check for uniqueness within a single list only. Specifically, it cannot be used to check for uniqueness of leafs within a sublist. But with unique-selector you can do more things like that. It is documented in the tailf_yang_extensions manpage.

Re: How to make sure IP is unique in a simple service to configure IP

erdemk — Wed, 24 Mar 2021 12:34:58 GMT

Hello Chandra,

I am not completely sure if i understood your question correct, but afaiu you want ip_address to be unique through out your network. Below are 2 options to do that :

option 1 :

leaf ip_address {
tailf:info "Select IP Address";
type enumeration {
enum 11.1.1.1;
enum 11.1.1.100;
enum 11.1.1.200;
}
must "count(../../colour[name != current()/../name]/ip_address = current()) = 0" {
error-message "ip address already in use.";
}

}

option 2:

list colour {
key name;

leaf name {
type string;
}

unique ip_address;

}

Are you looking for NSO trainings?

Nicklas Wagerth — Thu, 18 Mar 2021 13:12:05 GMT

Learning NSO hasn't been easier!

Although navigating the offerings may need some guidance.

You basically have two options, one instructor-led and one self-paced using free resources on DevNet. We of course recommend using both options.

Cisco Instructor-led Learning Path

To locate the Cisco Learning Offerings, Use the "Cisco Learning Locator" (https://learninglocator.cloudapps.cisco.com) and search for "NSO". It is really that simple! Note that the featured link on the right is updated and will take you there in one click.

If you do this, you will find three courses all instructor-led and delivered both physically and virtually.

NSO Essentials for Programmers and Network Architects, aka NSO 201 is where you start. NSO 201 is a 4-day course. Targeting audience: Network administrators, Solutions designers, and System installers,-integrators, and -administrators.

if you want to continue your learning journey there are two courses depending on your role. Both require that you completed NSO201. These are:

NSO Advanced for Python Programmers (NSO300) 4.0

Re: Welcome to the DNA Center SDK Support Community!

lemontan — Fri, 12 Mar 2021 13:00:52 GMT

Hi all,

I'm working with the DNA-C Multivendor SDK application and I have a problem, when defining the DNA-C server and then the GUI and SSH / Maglev access, I don't have the option to put ports. The DNA-C is in a lab and has the default ports changed, for example for MAGLEV instead of its default 22 it is 32222 and in the GUI instead of 443 it is 30443

Does anyone know if it is possible to change the default ports of the application when the DNAC server is defined? and if possible where is it done?

Hi Jan,

I went through the document shared by you. I was able to build the NED successfully but while connecting I am getting error:

result false
info Device ZTP6RPAJ01-Netconf does not advertise any known YANG modules

I checked my junos device is JUNOS 18.3R1.9. Is there a way to build netconf ned for these devices through NSO NETCONF ned builder feature?

Thanks,

Live Event & Video On-Demand

Individual Live Sessions

Telstra Network Transformation with Automation
Ross Manariti, Technical Product Owner - Resource Domain & Element Management, Telstra

Customer services across thousands of network appliances are still manually configured today. Capabilities, processes, and practices vary from platform to platform and amongst different administrative groups. This can and has led to poor customer experience, high cost of delivery & lost revenue opportunities. We decided to take a different approach to developed a multi-vendor, model-driven, highly-customizable system - capable of repeatable, predictable service and infrastructure resource configuration automation. This approach has seen us improve customer experience and standardize IT/Network interactions, enabling network services to be consumed digitally.

Customer Success: Cross-Domain and Multi-Layer Transport Network Automation
Naveen Kumar, Technical Lead, Cisco CX

The Customer is the largest telecommunication company in the area with its core businesses in fixed-line, mobile, broadband, and IoT services. Cisco as a partner is helping the Customer in their transformation journey towards the next-gen network which serves to meet their scale demand and agility for 5G, Broadband, and enterprise offerings. The Customer recognizes that automation is key for increased service velocity and operational efficiency by leveraging cutting-edge technologies. NSO is a major building block in this architecture for their multi-domain and multi-layer service orchestration solution for IP and extending it to the optical network. This session covers the details pertaining to the use cases and how the solution has evolved in conjunction with network design & build.

Service Design for Scaling
Ulrik Forsgren, Software Engineer, Cisco

The session guides you through common best practices and gives pointers to useful information. After the talk, you should be able to describe and motivate your design choices, as well as recognize questions to be asked next to meet future requirements.

Monitoring NSO: Understanding What’s Going On Inside
Kristian Larsson, Architect, Cisco

Kristian is the author of the OpenTelemetry exporter package for NSO, which exports metrics and traces from within NSO. Tag along to see how you can leverage observability data to understand the behavior of NSO and services in your environment.

On-Demand Sessions

Use Case: Optical Orchestration
Mark Swanborough, Software and Automation Practice Leader, Cisco CX
Krishna Shanmughom, Customer Delivery Software Architect, Cisco CX

Optical Automation using NSO – This presentation talks about how to use NSO for automating L0, L1, and L2 services on Cisco as well as third-party optical networks like Ciena, Huawei, etc thereby helping Service Providers achieving cross-domain orchestration. Also includes Optical automation case studies, challenges and lessons learned.

NSO Scale and Performance Tests
Anshu Narang, Software Engineering Technical Leader, Cisco

Help new users of NSO understand what to expect from NSO in terms of Scale and Performance for their use case(s). Share NSO Scale and Performance capabilities for Reference Use Cases i.e. NFVO (Virtualization) and T-SDN (Physical device configuration) Core FPs.

Technical Deep Dive: Monitoring NSO
Kristian Larsson, Architect, Cisco

A deep dive into NSO observability and the technical underpinnings of the opentelemetry-exporter package. See how it all works and learn how you can expand and build your own custom visualizations or how to instrument your own services for observability.

Auto Heal Your System
Eswaramoorthy Ramasamy, Software Consulting Engineer, Cisco CX

Auto healing is the highest level of automation anyone can achieve. In this session, we would be covering how auto-healing can be achieved with NSO and Open Source Monitoring tools.

Re: How to make sure IP is unique in a simple service to configure IP

Chandra L — Tue, 16 Feb 2021 14:12:36 GMT

Thank you for giving me this hint. I had a brief look, it is not a simple logic that I could easily implement in the current YANG file. Looks like it is going to complicate my current service. Probably for now, I will just let the user know that they have to take care of this duplicate IP manually.

Re: How to make sure IP is unique in a simple service to configure IP

nso20 — Tue, 16 Feb 2021 09:43:15 GMT

Hello,

I think this request needs python maapi intervention, you need to parse all the interfaces and check if any of them have ip address the same as the service is trying to configure. Then, in python, you can make your decision either fail and exit or just raise a log warning.

Webinar - Feb 18th - 10am PST - The Integrated NSO and ConfD Transaction Managers

Nabil_Michraf — Mon, 15 Feb 2021 19:45:59 GMT

If you are an NSO user, you are probably aware that when you write and read data from any of the NSO northbound interface agents, such as NETCONF, RESTCONF, CLI, MAAPI, etc., those agents are going through the NSO transaction manager before reaching the CDB "running" datastore and the southbound NEDs.

Even if you are aware that the NSO transaction manager is tightly integrated with all NSO components, when managing the network using the NSO device and/or service manager, there are a number of crucial decisions to consider. Such as, are you going to enable the NSO commit queues, are you going to make use of the logical datastores that comes with NMDA, how will you reconcile your services with a device that is out-of-sync, and what requirements for northbound interfaces will you have for the devices you deploy in your network?

Did you also know that, in the bigger picture, NSO’s transaction manager is extended by the devices transaction managers, that may be implemented by ConfD or not at all, and that NSO may be managing a hundred other transaction managers in parallel?

Even if the device is enabled by ConfD and its transaction manager, there are a quite a few things to consider when deciding on how to manage such devices and maximizing the value of a full-fledged transaction manager instead of the opposite.

In this 1h workshop, scheduled on February 18th, 10am PST, we will spend most of our focus on the integration between NSO and ConfD's transaction managers and go through the more common and impactful design decisions when integrating with the two while keeping the bigger picture in mind.

How to make sure IP is unique in a simple service to configure IP

Chandra L — Wed, 03 Feb 2021 12:48:24 GMT

Hi,

I have a simple service to configure an IP under loopback interface, but how do I delete the IP, if the one I am going to configure is pre-existing on another interface or at least give a warning that this IP is already in use?

Here is my yang file -

prefix colour;

import ietf-inet-types {
prefix inet;
}
import tailf-ncs {
prefix ncs;
}
import tailf-common {

}
list colour {

}

uses ncs:service-data;
ncs:servicepoint "colour";

leaf colour {

Code Coverage Of Your NSO Python Code

Ulrik Stridsman — Thu, 17 Dec 2020 14:58:36 GMT

For those of you who are using Python for you code, knows that there is only one way to be sure and it is to run the code. But how do you know what parts of you code have been executed?! I do very often put in print statements and look at the output and very often I find that I need to add more statements and to do that I need to restart the package. This time consuming and boring and thought I should share my experiences how to mitigate this problem.

During some other test related work I came across Coverage.py and it was much easier to use than I thought and can produce HTML reports that gives a very good overview and also details down to each line of code loaded to memory.

Here is one example to how to use it for a simple Python based service. The package name is python_service_template and will be run outside of NSO.

Installation of coverage:

pip3 install coverage

First you need to be able to stop the Python VM:s started by NSO. Add this to ncs.conf and reload or restart NSO:

<hide-group>
  <name>debug</name>
</hide-group>

Stop the running python-vm in the NSO cli:

admin@ncs# unhide debug
admin@ncs# python-vm stop name python_service_template
result OK

Start the service's Python VM on the command line. This has beed tested with a NSO local installation:

coverage run /Users/uforsgre/ncs-release/5.4.1/src/ncs/pyapi/ncs_pyvm/startup.py -l debug -i python_service_template

Now you will do your tests, creating services, modifing services, etc.

When you are done and ready to get truth, you stop the Python VM, again:

admin@ncs# python-vm stop name python_service_template
result OK

I am not sure if it works just to press ctrl-c in the terminal windows where service is running. I leave that to you to find out.

Now you will find a file .coverage in the directory where the service was running. To show a textual overview just run:

coverage report

To produce a more extensive HTML report run:

coverage html

The HTML report end up in a directory htmlcov and the overview looks like this, showing a summary of all used modules. It also has a seach function if you have a lot of files.

Click on any of the files will show a detailed view for that file. Here you can highlight lines the have been executed:

This is a view some lines highlighted as not executed:

Which I personally think is a good way of getting input to create tests to improve the coverage of my tests. Since I had 100% coverage in my service I am showing this part the application class in the NSO API, revealing that I have no actions in my service.

Let me know if you find this useful and have ideas how we can impore development of packages, services and other script for NSO.

New Learn by Doing Example Series

Jason Belk — Sat, 20 Feb 2021 02:09:31 GMT

I am the NSO Technical Evangelist in the NSO BU. I have started a series I am calling "Learn by Doing", which I take one topic to learn and one use case (as simple as possible, and as focused as possible) and create a repo with some simple explanation that will work on the DevNet NSO reservable sandbox .

I have made a few so far and they are on GitHub / DevNet Code Exchange:

https://developer.cisco.com/codeexchange/github/repo/jabelk/radius_server_example (FOR loops in XML templates and using IOS radius server config)

https://developer.cisco.com/codeexchange/github/repo/jabelk/ntp_server_example

(Service Template Conditionals, Foreach Template Device looping and using NTP IOS config)

https://developer.cisco.com/codeexchange/github/repo/jabelk/svi_verify_example

(Service Health Verification and Importing Packages, using Nexus / ASA SVI Config)

https://developer.cisco.com/codeexchange/github/repo/jabelk/ansible-nso-restconf

(Using Ansible RESTCONF modules to configure NSO, YAML and Infra as Code)

https://developer.cisco.com/codeexchange/github/repo/jabelk/python_nso_commit_flags

(Commit dry-run using Python API)

I have already asked for feedback in this discussion post, but would love to hear more thoughts people have, especially customers or potential customers. (And a big thanks to those who already responded!)

My question is this:

What parts of NSO would you like to see covered and/or what focused and simple use cases (that are feasible in a CML 2.0 virtual topology of IOS/XR/ASA/NX devices) are interesting to you?

Thanks!

Re: Reconciling out-of-band changes with NSO Service Configuration

ZAhmad04890 — Wed, 18 Nov 2020 19:33:09 GMT

Hi Dan,

Thanks for sharing, I have a question regarding developing python code, where I am using YANG service model and XML vendor templates and calling these service variables from(YANG and XML) through my python code. The package runs without any issues, However if I load the service.py file into IPython , I cannot print the values of service variables i.e YANG+XML, but just I can print the root variables lint root.connection or device.

My question is is there a way that I can print the values of service variables by loading the python code in iPython editor? or there is another way which is used by developers?

NSO Ansible Modules Migrated to Collections

Jason Belk — Wed, 04 Nov 2020 17:30:25 GMT

We officially have NSO as a Cisco Ansible collection, aligning to the new way Ansible handles non-core modules:

https://galaxy.ansible.com/cisco/nso

If you have issues or pull requests you can open them on the following collection repo:

https://github.com/CiscoDevNet/ansible-nso

Why did we do this?

Ansible has changed their software architecture to remove “non-core” modules from their distribution. NSO was previously a part of the Ansible distribution, but as a result of the most recent versions, must be installed manually through the collections / galaxy process. We are aligning to what Ansible has dictated in terms of the software distribution process for third party modules, and we are aligning to how other Cisco software products such as ACI and Meraki have already adopted this model. This was not as a result of some additional feature or functionality, but merely keeping up with Red Hat’s decision to change the way Ansible handles non-Red Hat modules.

What benefit is there to this change?

The value to having NSO in collections allows us to be more nimble in providing updates and keeping track of issues. Since the NSO Ansible code was buried in the monolithic Ansible Git Repository under the old architecture, and there were many, many, issues on Ansible and its suite of modules being opened and closed, it was harder to manage ownership and maintenance. Since our code is decoupled from the Ansible repo, if customers have issues or feature requests, they can submit them on the GitHub link above.

In addition to moving to the collection architecture, we are taking the chance to add in a few more examples into the documentation and have the examples align to the NSO Reservable Sandbox environment to make it easier for new users to get started.

From a pure functionality perspective, there should not be any change (apart from playbooks needing the new collections syntax), and in the long run it should help our team better manage the code base and keep on top of issues and feature requests as they come in.

GET https://{ise_hostname}:9060/ers/config/activedirectory

That should give you a "SearchResult" containing any AD joins you have on the ISE and give you the join ids you need for other queries.

As long as you're doing an authenticated GET and you've passed the desired "Content-Type" and "Accept" key/values in your header it should work.

Finesse 12.5 performance improvements - part 1. c10k

asrambik — Mon, 19 Oct 2020 08:21:24 GMT

The browser-based Finesse Agent Desktop 12.5, that ships with the Cisco Unified CCE / CCX contact center solutions, has made massive strides in the performance of its underlying infrastructure, which improves its throughput and reliability by an order of magnitude compared to Finesse 11.x and below.

This is part one of a series of posts from the engineering team that aims to describe the changes made in the 12.5 release and the resulting improvements.

Finesse Failover as a driving force for performance

Faster failover is one of the major improvements that was added in Finesse 12.5. Failover is the process by which the desktop reloads from the alternate Finesse server when it senses a problem with the currently connected server.

Finesse failover involves 2 major scenarios,

CTI Failover -

A breakage of the CTI connection above, causes Finesse server to go out of service, while it connects to the alternate side and re-initializes its in-memory state. The desktop will keep querying either sides, (preferring the current side) and ultimately reconnects to the Finesse server which comes into service. If the Finesse it is connected to, does not come back in service, the desktop has to be reloaded from the alternate Finesse.
Desktop Failover

When the browser running the Finesse desktop, faces disruption to the REST / HTTP connection or XMPP connection shown above, the desktop will reload from an active side and re-initialize its display state.

Nature of the challenge

A desktop reload, requires all the clients to reload the complete desktop & its resources from the alternate server within a very short window.

This operation is akin to a complete browser relaunch for the desktop and produces the same load as a login operation for a single client.

While shift changes and consequent user logins typically happen over a period of a few minutes, a browser failover would generate the entire load at the Finesse server in a much shorter time period, comprising of static HTTP resource loads and REST API calls from all the clients involved.

This made scaling thousands of clients to simultaneously become available in the shortest possible time, an exacting challenge.

Therefore, this requirement became the source of a major list of optimisations made to the Finesse desktop.

C10k Scale

One of the critical challenges faced by a web server is scale. In the initial days of Common Gateway Interface (CGI) web , HTTP servers used to serve a request by spawning a new process for each request, which was no doubt influenced by the Unix process spawning philosophy. Once the scale requirements grew, this was deemed to be too inefficient and thread-based request handling replaced it and has been more or less in force for a decade or two.

However, this architecture became inadequate beyond a certain scale, and c10k refers to the challenge of scaling a single web server to handle simultaneous connections from 10k clients. The act of spawning a different thread for each request becomes untenable at this scale due to the inherent in-efficiency present in context switching between different thread stacks and synchronising between them.

Asynchronous request processing architecture (which was definitely not pioneered by the web industry) was the next family of architecture that was picked by web servers to overcome this challenge.

Asynchronous request processing

Asynchronous requests refer to the nature of application code that aims to remove extra thread requirements by using only non-blocking API calls, which does not entail any waits. The results of the API calls are communicated over callbacks to the application code to process later.

This allows a single thread to run without being blocked and cater to multiple requests at the same time.

Finesse Tomcat

Finesse uses Apache Tomcat as its underlying web server. Tomcat HTTP connector with the fastest throughput (APR) uses synchronous style of request processing and improving upon this, became a requirement to meet the rate of requests pushed during a failover scenario. Though Tomcat does have a non-blocking connector, it handles only the TCP connection establishment phase in an async manner and does not seem to be able to scale the static resource processing in an async manner.

Therefore, Finesse opted to use Nginx since it has an asynchronous / event-based architecture, which was a departure from the thread-based request processing used by Apache Tomcat. Nginx was one of the pioneers of this new web server architecture and has now become one of the leading web servers in the industry.

Changes introduced to Finesse web server

These are the changes we introduced to improve the tomcat scale issues

Front Apache Tomcat with Nginx web server

The Apache Tomcat was modified to run only on localhost over HTTP and the Nginx server was configured to expose the ports required for the clients.

In tests involving 3000 clients firing all of the login time requests in a 1 minute window, the Nginx server was able to successfully finish the load, where the Apache server tried to cope, by increasing the thread count and finally ground to stop since the server could not deal with the number of threads created (amounting to 5000 odd threads, from which the test never recovers).

This failure is essentially the crux of the problem faced by threaded synchronous architectures.
Nginx performs SSL termination and provides HTTP/2 connectivity to clients.

Once the Apache tomcat was made local, it no longer required to process SSL requests and the SSL termination was taken over by Nginx, which allowed protocol support separate from the underlying Tomcat server.

Deploying Nginx as a proxy to Tomcat thus enabled HTTP/2 support, which would have otherwise, required a tomcat upgrade. If you are not familiar with benefits of using HTTP/2, here is why everyone should be using HTTP/2.
Cache static files at Nginx

Nginx’s cache flexibility allowed Finesse to serve the static HTML resource serving responsibility to the Nginx server. Once this is done, the REST API requests that drive the core functionality of Finesse are the only requests that the Finesse tomcat needs to handle.

Removing Tomcat from serving the countless number of requests reduces the load on the system (far fewer threads and CPU consumption) and provides better throughput to the REST request layer.
Cache possible REST API responses at Nginx

As part of the effort to reduce the number of requests that reach Tomcat, responses for the API calls that retrieve configuration was cached at Nginx for a very brief period of time. This ensured that after a single client had fetched this data, it would not hit the Apache Tomcat again for all other agents of the same team retrieving the same data.

This reduced the load on the server by a factor 20 or 30, depending on the team size. This reduced the impact of the desktop initialisations to a large extend. Since this data is cached only to cater to logins, it is cached for only a few seconds in a memory backed file system, thus removing any disk impact for the load.
Enable browser cache of static resources
Browser can cache static files and does not request for the full files if the cache-control headers are present. Nginx supports cache-control header configuration, which makes it easy to control this behavior. We pre-loaded all the static files from the secondary site and unless the browser cache is loaded, these resources are never pulled again.

This reduces the number of requests hitting the Finesse web server and those that do hit the server are served by the Nginx cache.
Caching of gadget requests

Finesse gadget functionality is structured as multiple iFrames created within the desktop’s page area, loading a specific gadget’s HTML. Once Nginx based HTTP response cache was available, caching semi-constructed gadget HTML’s for XML gadgets became possible and all the stock gadgets where moved to XML based gadgets.

Gadget HTML creation done by the Shindig web server was expensive due the parsing and caching it performs to modify the script and CSS includes, such that scripts will correctly refer to the Finesse server. Performing this repeatedly for all agents is a gross waste of the server’s capability and this has now become efficiently cached, with the aid of some clever scripts at the desktop, which can fill in a few remaining dynamic parts of the response.

By offloading this processing, a significant load was reduced again. If each desktop contains 5 gadgets, that is a saving of 20,000 VERY expensive requests.

Please note though that this optimisation is available only for static gadget URIs, and to make use of this, all stock gadgets that ship with the solution have been converted to use XML based URI’s.

CCE deployments performing upgrades, need to run a CLI to upgrade their LiveData gadget URI’s, after CUIC is upgraded.

Summary of Improvements

Connection handling is vastly improved. I.e. c10k compliance + HTTP/2 + SSL termination

The HTTP request handling infrastructure is vastly improved.
Reduction in CPU consumption from-
1. SSL offloading
2. reduced request processing at Tomcat
Reduction in no of HTTP calls due to
1. Efficient static resource caching.
2. REST response caching.
3. Gadget HTML response caching.
Resiliency

Sudden increase in load, can be handled effectively with improvements in connection handling, which otherwise breaks the old Tomcat server. Finesse is primarily a web application and the improvements made in its HTTP processing availability improves it resiliency during peak periods and load situations.
Security

Since Nginx is acting as physical layer of separation, much like a reverse proxy, between Tomcat & the HTTP request termination point, it provides an additional level of security, by shielding Tomcat and enforcing limits, before the request is evaluated by Tomcat.

Application code is tightly coupled with the Apache Tomcat server due to the usage of the Tomcat provided JEEE interfaces. However, no such restriction applies to the external proxy.

Therefore, this allows the product to react quickly and the client facing web server layer becomes easily upgradeable, which is a big plus from security perspective. Additional security checks can also be enabled at Nginx if so desired, using security modules like modsecurity.

Overall, this change has provided significant gains from all the above perspectives and enables new opportunities due to the flexibility it provides to the application stack.

Live Demos and a Cisco NSO Overview at Network Field Day 23 Event

Jason Belk — Fri, 09 Oct 2020 10:51:00 GMT

Hank Preston and Jason Belk presented at Network Field Day 23 to a network engineer audience. Jason shared his personal journey from network engineer to automation evangelist, and how Cisco Network Services Orchestrator (NSO) drew him deeper into automation as a network engineer. He then demoed some of NSO’s basic features on the CLI, showing how a network engineer could get started without having to learn any other coding skills yet. By watching this overview video, you will get a better idea of what Cisco NSO is and why it is relevant to network engineers.

Hank shared how he is using Cisco NSO in the DevNet Sandbox team to manage a variety of network devices and other infrastructure components. He gave a live demo in his pre-production environment, creating a new service instance which provisioned configuration across a number of devices.

His service behind the scenes used Python code and Yang to enforce his network standards automatically, so an engineer consuming his service from another team would only have to provide a few basic inputs and Cisco NSO would handle all the rest. Hank’s demo showcases some of Cisco NSO’s more advanced features, and shows the sky is the limit in terms of what the product can accomplish after you learn the basics.

The session was lively and interactive, including questions about how Cisco NSO compares to Ansible and how does NSO handle configuration rollbacks. The panelists asking the questions represented a variety of engineers from different backgrounds not from Cisco.

looks like the response does not contain the expected output.

try with a simple print(response_json) to debug. Maybe you have to go further up in the code.

Often in such sample scripts there is no exception handling or error checking done.

Just to be sure: use python3 as interpreter means run
