> Key: IGNITE-12943
> URL: https://issues.apache.org/jira/browse/IGNITE-12943

> Issue Type: Task

> Priority: Major
> 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?
