Milan Masek resolved IGNITE-16274.
----------------------------------
Resolution: Not A Bug
I've learned recently, metrics are 0 in default data region because
metricsEnabled property has to be explicitly set not only in
dataStorageConfiguration, but also for each of the data regions listed in
default-config.xml.
E.g.
{code:java}
<property name="dataStorageConfiguration">
<bean
class="org.apache.ignite.configuration.DataStorageConfiguration">
..
<property name="metricsEnabled" value="true"/>
<property name="dataRegionConfigurations">
<list>
<bean
class="org.apache.ignite.configuration.DataRegionConfiguration">
<property name="name" value="dynamicRegion"/>
<property name="metricsEnabled" value="true"/>
{code}
> Data Region OffheapUsedSize JMX metric reports 0
