Examples

Example of running psutil collector plugin and publishing data to Prometheus.

Set up the Snap framework

Ensure Snap daemon is running:

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

Download and load Snap plugins (paths to binary files for Linux/amd64):

$ snaptel plugin load snap-plugin-publisher-prometheus
$ snaptel plugin load snap-plugin-collector-psutil

Create a task manifest (see exemplary tasks), for example psutil-prometheus.json with following content:

{
  "version": 1,
  "schedule": {
    "type": "simple",
    "interval": "10s"
  },
  "workflow": {
    "collect": {
      "metrics": {
        "/intel/psutil/load/load1": {},
        "/intel/psutil/load/load15": {},
        "/intel/psutil/load/load5": {},
        "/intel/psutil/vm/available": {},
        "/intel/psutil/vm/free": {},
        "/intel/psutil/vm/used": {}
      },
      "publish": [
        {
          "plugin_name": "prometheus",
          "config": {
            "host": "127.0.0.1",
            "port": 80
          }
        }
      ]
    }
  }
}

Create a task:

$ snaptel task create -t psutil-prometheus.json

Watch created task:

$ snaptel task watch <task_id>

To stop previously created task:

$ snaptel task stop <task_id>

Limitations

This plugin only supports the "host" tag for now.
