ambari metrics collector going down

[#1]

Ambari metrics collector is going down because of lack of thread pools. How to increase the thread pool size for ambari metrics hbase. we are running hbase for metrics in distributed mode. Collector gows down within 5 minutes after restart.

[#2]

@Aravindan Vijayan, these 2 lines are not present in any of the 2 files mentiones in the url you gave. That means this is equivalent to getting commented out. so metrics at region level too are getting flooded. YEs the metrics collector host is cohosted with a datanode. but we are planning to move it to a dedicated admin host.

@ARUN

Here the instruction is to disable (exclude) HBase per region metrics to avoid data flooding.

That can be done by explicitly adding the following lines to the end of the file:

*.source.filter.class=org.apache.hadoop.metrics2.filter.GlobFilter
hbase.*.source.filter.exclude=*Regions*
