---------------------------------------
Summary: Document how to filter out metrics from registries
Key: IGNITE-12943
URL: https://issues.apache.org/jira/browse/IGNITE-12943
Project: Ignite
Issue Type: Task
Reporter: Denis A. Magda
Fix For: 2.8.1
As per `MetricExporterSpi.setExportFilter` contract, the user can filter out
metrics for a specific exporter instance. For instance, this is how we can ask
a JMX exporter instance to ignore the cache metrics:
{code}
JmxMetricExporterSpi jmxSpi = new JmxMetricExporterSpi();
jmxSpi.setExportFilter(mreg -> !mreg.name().startsWith(«cache»));
cfg.setMetricExporterSpi(jmxSpi);
{code}
We should add `Metrics Filtering` section to this documentation page [1]
explaining how to use the filtering. Also, I would clarify in the
`MetricExporterSpi.setExportFilter` JavaDocs that the method filters out
certain metrics from a specific exporter.
Also, should we possibly rename the method to
`MetricExporterSpi.setMetricsFilter` to make things crystal clear?
