Do you proactively manage your Cisco voice network?Do you know of network issues before end users?Or, are the end users your monitoring tool?Do you have a baseline of your voice network? Would you know what normal conditions are?
Operations Manager is used to monitor a Cisco voice network.Operations Manager provides a unified view of the entire IP communications infrastructure and presents the current operational status of each element of the IP communications network. It continuously and proactively monitors the current operational status of different IP communications elements such as Cisco CallManager, Cisco CallManager Express, Cisco Unity, Cisco Unity Express, Cisco IP Contact Center, and Cisco gateways, routers, and phones, and it provides diagnostic capabilities for faster trouble isolation and resolution. Operations Manager monitors and evaluates the current status of both the IP communications infrastructure and the underlyingtransport infrastructure in the network. It uses open interfaces such as Simple Network Management Protocol (SNMP) and Hypertext Transfer Protocol (HTTP) to remotely and proactively poll data from different devices in your IP communications deployment. It does not deploy any agent software on the devices being monitored and is nondisruptive to system operations.
In addition, when deploying Operations Manager, below are some guidelines:
·Follow the Operations Manager Deployment Guide.This document can be downloaded from www.cisco.com\go\cuomand is invaluable for any deployment.Only Cisco unified communication devices are supported.
·Use synthetic tests that replicate end-user activity and verify gateway availability and other configuration and operational aspects of the IP communications infrastructure.Use these tests to validate pre, or post -deployment scenarios.
·Create a WAN baseline test which then can be compared to future tests using the IOS IPSLA between Gateways and/or switches.
oThrough IP service-level agreement (SLA)-based diagnostic tests that can measure the performance of WAN links and measure node-to-node network quality.
oOne needs to activate the IPSLA agent on IOS before Operations Manager can utilize this agent.Typically, the IOS Command is “ip sla monitor responder”.
oNote, by using the IPSLA simultaneously on both the Gateway and the switch, one can measure hop-by-hop latency between these devices.
·Presents service-quality alerts by using the information available through Cisco Unified Communications Service Monitor (when it is also deployed). Service Monitor will act as a CDR billing collector.The Unified Communications Manager is configured to send Call Detail Records (CDRs) to Service Monitor which contains Quality of Service measurements for that call.(For earlier CallManager versions, Service Monitor will collect the CDR from the CM server, rather than the CDR being sent as in later versions).Service Monitor can be co-resident with Operations Manager.The same software package installs both Operations Manager (OM) and Service Monitor (SM).It is only a matter of licensing to activate either OM, SM or both.
·Remember to provide a unique cluster id name for every Communications Manager cluster being managed.This is done in the Publisher UCM “Service Parameters” page.
·Monitor T1/E1 Gateway trunk utilization
·Enables tracking of IP phone inventory, tracks IP phone status changes, and creates a variety of reports that document move, add, and change operations on IP phones in the network.For this capablity, one needs to monitor the Cisco switch to which the IP phones are connected.
