Idle OS Jitter

Plugin: idlejitter.plugin Module: idlejitter.plugin


Monitor delays in timing for user processes caused by scheduling limitations to optimize the system to run latency sensitive applications with minimal jitter, improving consistency and quality of service.

A thread is spawned that requests to sleep for fixed amount of time. When the system wakes it up, it measures how many microseconds have passed. The difference between the requested and the actual duration of the sleep, is the idle jitter. This is done dozens of times per second to ensure we have a representative sample.

This collector is supported on all platforms.

This collector only supports collecting metrics from a single instance of this integration.

Default Behavior


This integration will run by default on all supported systems.


The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.



No action required.



The configuration file name for this integration is netdata.conf.

The file format is a modified INI syntax. The general structure is:

    option1 = some value
    option2 = some other value

    option3 = some third value

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config netdata.conf


This integration only supports a single configuration option, and most users will not need to change it.

Name Description Default Required
loop time in ms Specifies the target time for the data collection thread to sleep, measured in miliseconds. 20 no


There are no configuration examples.


Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per Idle OS Jitter instance

This scope has no labels.


Metric Dimensions Unit
system.idlejitter min, max, average microseconds lost/s


There are no alerts configured by default for this integration.
