-Idle jitter is a measure of delays in timing for user processes caused by scheduling limitations.
-
-## How Netdata measures idle jitter
-
-A thread is spawned that requests to sleep for 20000 microseconds (20ms).
-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 at most 50 times per second, to ensure we have a good average.
-
-This number is useful:
-
-- In multimedia-streaming environments such as VoIP gateways, where the CPU jitter can affect the quality of the service.
-- On time servers and other systems that require very precise timing, where CPU jitter can actively interfere with timing precision.
-- On gaming systems, where CPU jitter can cause frame drops and stuttering.
-- In cloud infrastructure that can pause the VM or container for a small duration to perform operations at the host.
-
-## Charts
-
-idlejitter.plugin generates the idlejitter chart which measures CPU idle jitter in milliseconds lost per second.
-
-## Configuration
-
-This chart is available without any configuration.
