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, and that you have at least a Centreon IT 100 Edition that provides Centreon Monitoring Connectors (your license is already set up).

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. The monitoring procedure for the Cisco standard Monitoring Connector includes an example.

Network flow​

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

On the poller​

Connect to your poller using SSH and install the Cisco standard plugin (see the monitoring procedure for the Cisco standard Monitoring Connector for more information):

dnf install centreon-plugin-Network-Cisco-Standard-Snmp

On the central server​

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

  2. Input the following information:

  • The name of the router (1)
  • A description of the router (2)
  • The IP address of the router (3)
  • The SNMP version and community (4)
  • Select the poller that will monitor the device (keep "Central" if you have no other poller) (5)

  3. Go to Configuration > Services > Services by host. A set of indicators has been created automatically.

    You can also use the shortcut beside the host's name to go directly to Configuration > Services > Services by host. The list will be filtered by host name:

  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.
