PQS metrics - https://issues.apache.org/jira/browse/PHOENIX-3655
Phoenix Query Server metrics
https://issues.apache.org/jira/browse/PHOENIX-3655
The following properties is added along with the defaults
1. "phoenix.query.server.metrics" - default is true ( means pqs will
collect metrics by default )
2. "phoenix.query.server.metrics.report.interval.ms" - default is 30 sec (
every 30 sec, the global metrics will be output to sink )
3. "phoenix.query.server.metrics.type.of.sink" - default is file ( other
option is slf4j)
4. "phoenix.query.server.filesink.filename" - Filename if using fileSink
(default is /tmp/pqsSinkFile)
if user setup "phoenix.query.server.metrics" in hbase-site.xml to true, we
add the following properties to JDBC connection
(QueryServices.COLLECT_REQUEST_LEVEL_METRICS= true). The starts the metrics
collect at request level.
There are two types of metrics
1. Global - This metrics is collect every interval and pushed to sink (
File or Slf4j). Apart from this, it is also exposed in JMX via Mbeans.
2. Request - These metrics is collected at statement and connection close
level. Once collected, it is pushed to the sink. These metrics are not exposed
via JMX as metrics are for specific table requests. For requests level
metrics, we have file and Slf4j ( LOG) as types of sink. So, the metrics will
be pushed to a specified file or log file .

> 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.
