-------------------------------------
Summary: Add OpenMBean CompositeData and TabularData support for
JMX metric exporter
Key: IGNITE-25505
URL: https://issues.apache.org/jira/browse/IGNITE-25505
Project: Ignite
Issue Type: Improvement
Reporter: Denis Chudov
*Motivation*
As for now, composite metrics are exported as plain strings, which is not the
best way for complex structured objects and it doesn't give a convenient way to
watch them in external tools that use JMX. OpenMBean has a conventional way to
solve this.
*Definition of done*
We should add OpenMBean CompositeData (and probably TabularData) support for
jmx exporter:
* as a prerequisite, CompositeMetric in metric framework should be extended in
order to provide all composite metric information for jmx exporter to create
CompositeData instance (items, their types, etc.);
* all CompositeMetrics in AI should support these CompositeMetric extension;
* after that, jmx exporter should be improved to create CompositeData for
CompositeMetric.
