Getting Started

System Requirements

Operating systems

All OSs currently supported by snap:

  • Linux/amd64


Download meminfo plugin binary:

You can get the pre-built binaries for your OS and architecture at plugin's GitHub Releases page.

To build the plugin binary:


Clone repo into $GOPATH/src/

$ git clone<yourGithubID>/snap-plugin-collector-meminfo.git

Build the plugin by running make within the cloned repo:

$ make

This builds the plugin in ./build

Configuration and Usage

  • Set up the Snap framework

  • If /proc resides in a different directory, say for example by mounting host /proc inside a container at /hostproc, a proc_path configuration item can be added to snapteld global config or as part of the task manifest for the metrics to be collected.

As part of snapteld global config

          proc_path: /hostproc

Or as part of the task manifest

    "workflow": {
        "collect": {
            "metrics": {
	      "/intel/procfs/meminfo/mem_total": {}
	    "config": {
	      "/intel/procfs": {
                "proc_path": "/hostproc"
  • Load the plugin and create a task, see example in Examples.


Collected Metrics

List of collected metrics is described in


Example running meminfo plugin and writing data to a file using snap-plugin-publisher-file.

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:

$ wget
$ wget
$ snaptel plugin load snap-plugin-publisher-file
$ snaptel plugin load snap-plugin-collector-meminfo

See available metrics for your system

$ snaptel metric list

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

  "version": 1,
  "schedule": {
    "type": "simple",
    "interval": "1s"
  "workflow": {
    "collect": {
      "metrics": {
        "/intel/procfs/meminfo/mem_free": {},
        "/intel/procfs/meminfo/mem_available": {},
        "/intel/procfs/meminfo/mem_total": {},
        "/intel/procfs/meminfo/mem_used": {}
      "config": {
        "/intel/procfs": {
          "proc_path": "/proc"
      "publish": [
          "plugin_name": "file",
          "config": {
            "file": "/tmp/published_meminfo.log"

Create a task:

$ snaptel task create -t meminfo-file.json

Watch created task:

$ snaptel task watch <task_id>

To stop previously created task:

$ snaptel task stop <task_id>


There isn't a current roadmap for this plugin, but it is in active development. As we launch this plugin, we do not have any outstanding requirements for the next release. If you have a feature request, please add it as an issue and/or submit a pull request.
