> Phoenix Query Server runs a separate process compared to its thin client. Metrics collection is currently done by PhoenixRuntime.java i.e. at Phoenix driver level. We need the following
> 1. For every jdbc statement/prepared statement/ run by PQS , we need capability to collect metrics at PQS level and push the data to external sink i.e. file, JMX , other external custom sources. 
> 2. Besides this global metrics could be periodically collected and pushed to the sink. 
> 2. PQS can be configured to turn on metrics collection and type of collect ( runtime or global) via hbase-site.xml
> 3. Sink could be configured via an interface in hbase-site.xml.
