Monitoring network interfaces using SNMP

Overview

MetricsHub can leverage the SNMP protocol (v1, v2c, or v3) to monitor network devices such as Ethernet switches, UPS, or network interfaces^[1], provided that an SNMP agent is installed on the resource and the connection is configured.

In the example below:

• we configured MetricsHub to monitor a switch using SNMP v2c
• we displayed the total traffic in bytes/s in a Grafana Dashboard

Procedure

To monitor our switch:

1. In the config/metricshub.yaml file, we create the resource alcatel-switch with the following attributes:

   • hostname: alcatel-switch-01
   • host type: network

       resources:
         alcatel-switch:
           attributes: 
             host.name: alcatel-switch-01
             host.type: network
   

2. We configure MetricsHub to connect to the network switch using the SNMP v2c protocol and the public community

           protocols:
             snmp:
               version: v2c
               community: public
   

Here is the complete YAML configuration to be added to config/metricshub.yaml to monitor the switch:

    resources:
      alcatel-switch:
        attributes: 
          host.name: alcatel-switch-01
          host.type: network
        protocols:
          snmp:
            version: v2c 
            community: public
