thanks for that.
Yes, each server will have a monitoring agent (that sends back metrics)

Hi All
We are using Cloudera Enterprise edition which is not supporting SNMP
support for Hbase and licence is quite expensive.
does any one know any 3rd party tool which can support SNMP for Hbase.
Does Hbase it self support for SNMP? if yes how can i send traps or poll on

builds on OpenTSDB, which itself is an HBase application. It looks like the

Thanks for that link Otis! This indeed allows completely overriding the
default monitoring by Hbase, however what we are looking at really is
capturing some additional metrics over and above what the monitoring is
already generating.
So, we figured a way to achieve that through co-processors as
