Getting maxSize for data region in Apache Ignite - caching

Question

I am Using Apache Ignite 2.8.0.
Now my persistence is disabled, and i was set my maxSize as 400Mib by,
<property name="dataStorageConfiguration">
<bean class="org.apache.ignite.configuration.DataStorageConfiguration">
<property name="metricsEnabled" value="true"/>
<property name="defaultDataRegionConfiguration">
<bean class="org.apache.ignite.configuration.DataRegionConfiguration">
<property name="metricsEnabled" value="true"/>
<property name="name" value="Default_Region1"/>
<!-- Setting the size of the default region to 4GB. -->
<property name="maxSize" value="#{400L * 1024 * 1024 }"/>
<!--<property name="persistenceEnabled" value="true"/> -->
</bean>
</property>
</bean>
</property>
Now i am running this in my browser,
http://localhost:8080/ignite?cmd=dataregion
this is my response for Default_Region1,
{"name":"Default_Region1","totalAllocatedPages":0,"totalUsedPages":0,"totalAllocatedSize":0,"allocationRate":0.0,"evictionRate":0.0,"largeEntriesPagesPercentage":0.0,"pagesFillFactor":0.0,"dirtyPages":0,"physicalMemoryPages":0,"physicalMemorySize":0,"usedCheckpointBufferPages":0,"usedCheckpointBufferSize":0,"checkpointBufferSize":0,"pageSize":4096,"offHeapSize":0,"pagesReplaceRate":0.0,"pagesReplaced":0,"pagesReplaceAge":0.0,"offheapUsedSize":0,"pagesRead":0,"pagesWritten":0}
i didn't find the maxSize as 400Mib in response, How can i get that my MaxSize is 400Mib by using http request?

I'm not sure about HTTP, but DataRegionMetricsMXBean has getMaxSize() accessor.
You can execute compute tasks from REST so you can implement a task that does that, call it via exe REST call.
