Monitor your first Cisco router

Monitoring a Cisco Router with SNMP

In this tutorial, we're assuming that your Centreon platform is installed and running well.

Your Cisco router will be monitored using the Cisco standard Monitoring Connector. (More about Monitoring Connectors here).

Prerequisites

On the Cisco router you want to monitor

The first step is to activate and configure an SNMP service on your Cisco device. Please refer to the documentation of your Cisco device to find out how to configure the SNMP service.

Network flow

The target device must be reachable from the Centreon Poller on the UDP/161 SNMP port.

On the central server

In the web interface, go to Configuration > Monitoring Connector Manager, search for the Cisco standard Monitoring Connector; and install it:

  4. Deploy the configuration.

  5. Go to Monitoring > Resources Status and select All from the Resource status filter. At first, the resources appear with the status Pending, which means that no checks have been executed yet:

    After a few minutes, the first results of the monitoring appear:

    If not all services are in an OK state, check what is causing the error and fix the problem.
