Prometheus SNMP Generator for Edgerouter

This generates an snmp-exporter configuration suitable for gathering a bunch of useful stats from edgerouter devices. This was originally based on snmpwalking an Edgerouter Lite, but should be relevant for most other devices in the product line.

Usage

Take the checked in snmp.yml and run snmp-exporter with it, ex:

docker run --rm -p 9116:9116 -v `pwd`/snmp.yml:/etc/snmp_exporter/snmp.yml prom/snmp-exporter

Then query it with your edgerouter:

curl "localhost:9116/snmp?target=192.168.1.1&module=ubiquiti_edgemax"

Once working, use a snippet like the following to have prometheus start ingesting these:

scrape_configs:
  - job_name: 'snmp'
    static_configs:
      - targets:
        - 192.168.1.1  # SNMP device.
    metrics_path: /snmp
    params:
      module: [ubiquiti_edgemax]
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: my-service-name:9116  # The SNMP exporter's Service name and port.

Regenerating snmp.yml

The provided generator.yml is what was used to generate the snmp.yml. To regenerate it:

docker run --rm \
  -v /usr/share/snmp/mibs:/root/.snmp/mibs \
  -v $PWD/generator.yml:/opt/generator.yml:ro \
  -v $PWD/:/opt/ snmp-generator generate

This assumes you have net-snmp mibs installed locally
