Getting Started

System Requirements

  • golang 1.7+ - needed only for building
  • This Plugin compatible with kernel > 2.6
  • Linux/x86_64

Operating systems

  • Linux/amd64


Download the plugin binary:

You can get the pre-built binaries for your OS and architecture under the plugin's release page. For Snap, check here.

To build the plugin binary:

Fork Clone repo into $GOPATH/src/

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

Build the snap use plugin by running make within the cloned repo:

$ make

This builds the plugin in ./build/

Configuration and Usage

Set up the snap framework.

Load the plugin and create a task, see example in Examples.


The Utilization Saturation and Errors (USE) Method is a methodology for analyzing the performance of any system. It directs the construction of a checklist, which for server analysis can be used for quickly identifying resource bottlenecks or errors. It begins by posing questions, and then seeks answers, instead of beginning with given metrics (partial answers) and trying to work backwards (1). Brendan D. Gregg is an author of USE methodology.

Collected Metrics

List of collected metrics is described in


Example of running snap use 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-use
$ snaptel plugin load snap-plugin-publisher-file

Create a task manifest file (exemplary files in [examples/tasks/] (examples/tasks/)):

  interval: 1s
  type: simple
version: 1
      /intel/use/compute/saturation: {}
      /intel/use/compute/utilization: {}
      /intel/use/memory/saturation: {}
      /intel/use/memory/utilization: {}
      /intel/use/network/eth0/saturation: {}
      /intel/use/network/eth0/utilization: {}
      /intel/use/storage/sda/saturation: {}
      /intel/use/storage/sda/utilization: {}
        plugin_name: file
          file: /tmp/use_metrics

Download an example task file and load it:

$ curl -sfLO
$ snaptel task create -t use-file.yml

See realtime output from snaptel task watch <task_id> (CTRL+C to exit)

$ snaptel task watch 480323af-15b0-4af8-a526-eb2ca6d8ae67

This data is published to a file /tmp/use_metrics per task specification
