Snap collector plugin - load
This plugin collects metrics from /proc/loadavg kernel interface about load average figures giving the number of jobs in the run queue (state R) or waiting for disk I/O (state D) averaged over 1, 5, and 15 minutes.
It's used in the Snap framework.
All OSs currently supported by Snap:
Download the plugin binary:
You can get the pre-built binaries for your OS and architecture from the plugin's GitHub Releases page. Download the plugin from the latest release and load it into
/opt/snap/plugins is the default location for Snap packages).
To build the plugin binary:
Clone repo into
$ git clone https://github.com/<yourGithubID>/snap-plugin-collector-load.git
Build the Snap load plugin by running make within the cloned repo:
This builds the plugin in
Configuration and Usage
Plugin may be additionally configured with path to
/proc/loadavg file. It may be useful for running plugin in Docker container.
Example configuration provided in Examples
In case configuration is not provided in task manifest, plugin will use default path
This plugin has the ability to gather the following metrics:
|/intel/procfs/load/min1||number of jobs in the run queue (state R) or waiting for disk I/O (state D) averaged over 1 minute|
|/intel/procfs/load/min5||number of jobs in the run queue (state R) or waiting for disk I/O (state D) averaged over 5 minutes|
|/intel/procfs/load/min15||number of jobs in the run queue (state R) or waiting for disk I/O (state D) averaged over 15 minutes|
|/intel/procfs/load/min1_rel||number of jobs in the run queue (state R) or waiting for disk I/O (state D) averaged over 1 minute per core|
|/intel/procfs/load/min5_rel||number of jobs in the run queue (state R) or waiting for disk I/O (state D) averaged over 5 minutes per core|
|/intel/procfs/load/min15_rel||number of jobs in the run queue (state R) or waiting for disk I/O (state D) averaged over 15 minutes per core|
|/intel/procfs/load/runnable_scheduling||The number of currently runnable kernel scheduling entities (processes, threads).|
|/intel/procfs/load/existing_scheduling||The number of kernel scheduling entities that currently exist on the system|
Example of running Snap load collector and writing data to file.
In terminal go to examples/tasks directory and execute
$ cd examples/tasks && ./run-mock-load.sh
Script will start docker container in which it will download load collector, passthru processor and file publisher. Then it will start Snap daemon, load all plugins and start example task.
