Overview

Monitors process load on the host. Process load is the average number of running or waiting processes over a certain time period (1, 5, and 15 minutes).

See http://www.brendangregg.com/blog/2017-08-08/linux-load-averages.html for a good explanation of load on Linux.

This monitor is only available on Linux.

Configuration

To activate this monitor in the Smart Agent, add the following to your agent config:

monitors:  # All monitor config goes under this key

   ...  # Additional config

For a list of monitor options that are common to all monitors, see Common Configuration.

Metrics

These are the metrics available for this monitor. Metrics that are categorized as container/host (default) are in bold and italics in the list below.

• load.longterm (gauge)
  Average CPU load of the system over the last 15 minutes. If the perCPU config option is true, this will be the average load per CPU.
• load.midterm (gauge)
  Average CPU load of the system over the last 5 minutes. If the perCPU config option is true, this will be the average load per CPU.
• load.shortterm (gauge)
  Average CPU load of the system over the last minute. If the perCPU config option is true, this will be the average load per CPU.

Non-default metrics (version 4.7.0+)

To emit metrics that are not default, you can add those metrics in the generic monitor-level extraMetrics config option. Metrics that are derived from specific configuration options that do not appear in the above list of metrics do not need to be added to extraMetrics.

To see a list of metrics that will be emitted you can run agent-status monitors after configuring this monitor in a running agent instance.
