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, 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
