--------------------------------------
Summary: [doc] Document SizeUsedByData metric for data region
monitoring
Key: IGNITE-28795
URL: https://issues.apache.org/jira/browse/IGNITE-28795
Project: Ignite
Issue Type: Improvement
Components: documentation
Reporter: Ignite TC Bot
The SizeUsedByData metric is available in the io.dataregion.{region_name}
registry, but it is not described in the user documentation.
Current docs explain data region monitoring through TotalAllocatedSize,
PagesFillFactor, TotalUsedPages, PhysicalMemoryPages, and PhysicalMemorySize,
and the control.sh metric example for io.dataregion.default does not include
SizeUsedByData.
This follow-up should document:
- what SizeUsedByData represents
- how it differs from TotalAllocatedSize, OffheapUsedSize, and
PhysicalMemorySize
- how to use it when monitoring data region usage
- the updated io.dataregion metric listing and control.sh example output
Related implementation origin: IGNITE-17728 Improve data size-related metrics.
