Tomek Rękawek commented on OAK-6582:
------------------------------------

I've analyzed the MBeans registered by the DocumentNodeStoreService and SegmentNodeStoreService:

h3. SegmentNodeStoreService

h4. CacheStatsMBean:

* Segment Cache
* String Cache
* Template Cache
* String deduplication cache stats
* Template deduplication cache stats
* Node deduplication cache stats

h4. Maintenance MBeans:

* Segment node store revision garbage collection (SegmentRevisionGC)
* Revision garbage collection (RevisionGCMBean)
* FileStore statistics (FileStoreStatsMBean)
* Segment node store checkpoint management (CheckpointMBean, for role=null)
* Segment node store blob garbage collection (BlobGCMBean, for role=null)
* Segment node store backup/restore (FileStoreBackupRestoreMBean)
* SegmentNodeStore statistics (SegmentNodeStoreStatsMBean)

h3. DocumentNodeStoreService registers:

h4. CacheStatsMBean:

* Document-NodeState
* Document-NodeChildren
* many diff cache stats
* many DocumentStore cache stats
* BlobStore-MemCache
* PersistentCache.NodeCache.* (PersistentCacheStatsMBean)

h4. Maintenance MBeans:

* Document node store checkpoint management (CheckpointMBean)
* Document node store management (DocumentNodeStoreMBean)
* DocumentStore Statistics (DocumentStoreStatsMBean)
* Document node store blob garbage collection (BlobGCMBean)
* Document node store revision garbage collection (RevisionGCMBean)
* Document node store revision garbage collection statistics (RevisionGCStatsMBean)
* BundlingConfigObserver (BackgroundObserverMBean)

> We should validate how the MBeans currently behave in a composite setup, whether any
unwelcome interactions arise due to that, and also see if we need to add/change MBeans.
