NSO devel-c no registration found for callpoint access/service_create of type=external

Hi Experts.

I'm building an NSO 'access' service just like the one on youtube (Understand how to use Cisco NSO to build a service for a specific configuration - YouTube)  with only difference that I'm using the python skeleton.

every works fine until I want to commit dry-run the configuration which gives me the following error:

admin@ncs# show packages package oper-status

Has anyone an idea where I must look in order to repair the issue ?

my main.py is as follows (default information is onmitted)

# -*- mode: python; python-indent: 4 -*-

import ncs

from ncs.application import Service

# ------------------------

# SERVICE CALLBACK EXAMPLE

# ------------------------

class ServiceCallbacks(Service):

    # The create() callback is invoked inside NCS FASTMAP and

    # must always exist.

    @service.create

    def cb_create(self, tctx, root, service, proplist):

        self.log.info('Service create(service=', service._path, ')')

        vars = ncs.template.Variables()

        template = ncs.template.Template(service)

        vars.add('VLAN', '1100')

        template.apply('access-template', vars)

        self.log.debug('access vlan: ',  service.VLAN)


With kind regards,


Michel

Hi Michel,

 

Check that you have python installed (try executing it from the command line). Needs to be minimum version of 2.7.5 or 3.4.

 

Check the python process is running for your service. Easiest way is to check the logs directory, there should be a file called ncs-python-vm-<service-name>.log (i.e. ncs-python-vm-access.log). If the file is there, check the contents to see if the process has crashed.

 

If the file is missing or the process has crashed try running "packages reload" from ncs_cli. Or try restarting NSO. Also if the process is not running ensure you have the correct entry in package-meta-data.xml. This should have been created automatically when you created the package if you choose one of the python service-skeleton options. You should have an entry which looks something like:

 

 

  <component>
    <name>main</name>
    <application>
      <python-class-name>access.main.Main</python-class-name>
    </application>
  </component>

 

 

Finally, ensure that the callpoint in register_service exactly matches the servicepoint ("access") in your yang file. You've said you've omitted the default information from the python main.py so I can't see it, but check you have something like this:

 

# ---------------------------------------------
# COMPONENT THREAD THAT WILL BE STARTED BY NCS.
# ---------------------------------------------
class Main(ncs.application.Application):
    def setup(self):
        # The application class sets up logging for us. It is accessible
        # through 'self.log' and is a ncs.log.Log instance.
        self.log.info('Main RUNNING')

        # Service callbacks require a registration for a 'service point',
        # as specified in the corresponding data model.
        #
        self.register_service('access', ServiceCallbacks)

    def teardown(self):
        # When the application is finished (which would happen if NCS went
        # down, packages were reloaded or some error occurred) this teardown
        # method will be called.

        self.log.info('Main FINISHED')

 

I have a problem similar to this. I have NSO 5.2.1 installed on my Mac. Now, no services work anymore, including services that worked before. I get this error:

admin@ncs(config-vlan_mappings-32)# commit dry-run outformat xml                                                                             
Aborted: no registration found for callpoint newSubAccess-servicepoint/service_create of type=external

It looks like the python process is not running for my services, because the ncs-python-vm-<service-name>.log is not created for new services. What can I do in that case?

Seems like python is running on my Mac:

# ncs-run % python --version
Python 3.7.3
# ncs-run % python2 --version
Python 2.7.16
# ncs-run % python3 --version
Python 3.7.3

I get this in ncs --status output:

But also this:

  id=newSubPOI-servicepoint ** not registered
  id=open-net-access-servicepoint ** not registered
  id=open-net-core-servicepoint ** not registered
  id=test_yang-servicepoint ** not registered

What do you think is wrong? Have I screwed up environmental variables like $PATH or something else?

 

I'm also facing similar issue .

while trying to commit  "Aborted: no registration found for callpoint" observed 

Service points are also  showing as not registered 

Is there any update on this ..?
