Hi ActiveMQ has three values: 1. StorePercentUsage is the % of persistent messages store. If use with KahaDB, it's % of the disk used by KahaDB. 2. TempPercentUsage is the % of disk used for non persistent messages spool space. 3. MemoryPercentUsage is the % of assigned memory for the broker entities (destinations, cache, ...). It should be lower than heap size.
I hope it helps.
