Hello, Igniters! At the moment metrics on system region are disabled on node start. User-defined regions can be tuned to have enabled metrics via region configuration (org.apache.ignite.configuration.DataRegionConfiguration#setMetricsEnabled) To enable metrics on system region users should use non-public API or use deprecated JMX bean (org.apache.ignite.mxbean.DataRegionMetricsMXBean#enableMetrics) for it, which doesn't solve problem because it needs human attention when node restarts.
I want to add a new property to *org.apache.ignite.configuration.DataStorageConfiguration* which enables or disables collection of metrics on system region (aka sysMemPlc) on node start. API change add new public methods: 1. *org.apache.ignite.configuration.DataStorageConfiguration#isSystemRegionMetricsEnabled()* 2. *org.apache.ignite.configuration.DataStorageConfiguration#setSystemRegionMetricsEnabled(boolean)* WDYT? -- Best regards, Eduard.
