I haven't seen this problem anymore. Hmm. Just for kicks, I increased from 5GB of heap to 8GB of heap. Heap increase period (when heap steadily increases then drops): 5GB: 6 hours 8GB: 12 hours This is 8000 metrics/minute, single RHQ instance and 2 instances of Cassandra. I have four (well eight) instances of Cassandra and not a problem. |
Created attachment 819546 [details] Heap usage Description of problem: I have a two node test cluster, serving about 200 agents. The heap size hovers around 50% for both Cassandra servers, but sometimes inches up to 80%. The 'max' is around 80% and hasn't gone over. I have about 5GB of heap for both nodes, so there is plenty of size. I don't think it's a concern, so I'd rather only get alerted if heap > 90% or something really critical. See the attached screenshot. Version-Release number of selected component (if applicable): 4.9 How reproducible: Daily or so
