Aaron Lindsey reassigned GEODE-1210:
------------------------------------
Assignee: Barry Oglesby
Is this still an issue? If so, what is the expected behavior for a partitioned
region DiskDirectoryStats?
> MemberMBeanBridge DiskDirectoryStats are not monitored for PartitionedRegions
> -----------------------------------------------------------------------------
>
> Key: GEODE-1210
> URL: https://issues.apache.org/jira/browse/GEODE-1210
> Project: Geode
> Issue Type: Bug
> Components: jmx
> Reporter: Barry Oglesby
> Assignee: Barry Oglesby
> Priority: Major
> Labels: observability
>
> This means that {{TotalDiskUsage}} is 0 for {{PartitionedRegions}}.
> The member's {{TotalDiskUsage}} JMX attribute comes from
> {{MemberMBeanBridge.getTotalDiskUsage}} which does:
> {noformat}
> public long getTotalDiskUsage() {
> long diskSpaceUsage = regionMonitor.getDiskSpace();
> return diskSpaceUsage;
> }
> {noformat}
> The {{regionMonitor}} gets the {{diskSpace}} by monitoring the
> {{DiskDirectoryStats}} of all its persistent {{Regions}}.
> For each region, {{MemberMBeanBridge.addRegion}} adds the
> {{DiskDirectoryStats}} of that region to its {{regionMonitor}}.
> If the region is a {{PartitionedRegion}}, then its {{DiskRegion}} is null
> since the {{DiskRegions}} are on the {{BucketRegions}} so no
> {{DiskDirectoryStats}} are monitored.
> This code in {{MemberMBeanBridge.addRegion}} falls through for
> {{PartitionedRegions}} since {{dr}} is null:
> {noformat}
> DiskRegion dr = l.getDiskRegion();
> if(dr != null){
> for(DirectoryHolder dh:dr.getDirectories()){
> addDirectoryStats(dh.getDiskDirectoryStats());
> }
> }
> {noformat}
