Configuration and Usage


Collected Metrics

This plugin collects the raw counters and a few other metrics from etcd. It is focused on the ones which are easily parsable and excludes ones which are formatted specifically for a Prometheus metric. There are also a handful of derivatives which take a sum over count average. List of metrics collected by this plugin can be found in file.


Example of running Snap etcd collector and writing data to file.

Ensure Snap daemon is running:

  • initd: service snap-telemetry start
  • systemd: systemctl start snap-telemetry
  • command line: snapteld -l 1 -t 0 &

Download and load Snap plugins:

$ wget
$ wget
$ chmod 755 snap-plugin-*
$ snaptel plugin load snap-plugin-collector-etcd
$ snaptel plugin load snap-plugin-publisher-file

See all available metrics:

$ snaptel metric list

Download an example task file and load it:

$ curl -sfLO
$ snaptel task create -t task-etcd.json
