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.
This integration will run by default on all supported systems.
The default configuration for this integration does not impose any limits on data collection.
The default configuration for this integration is not expected to impose a significant performance impact on the system.
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.
|system.idlejitter||min, max, average||microseconds lost/s|
There are no alerts configured by default for this integration.
No action required.
The configuration file name for this integration is
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.
|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.
