Hi All,
I guess we may start the discussion on how we want the metrics collection to be
designed for Phoenix Query Server.
I would lay down options and you can provide your input to them ( or even add
another option)
1. Write a layer to convert from the Phoenix internal representation to the
metrics system of choice (a shim). -- as suggested by [~elserj]
2. write the request level metrics at event close ( statement close, connection
close ) and push the data down to Phoenix tables itself. We would create
bootstrap tables in Phoenix and write down every request/global level metrics.
That way, we will have options to collect the metrics later by querying the
tables. We can have Phoenix level parameter which will limit the length of time
metrics could be retained.
Please advise.
thanks
Rahul

> Environment: Linux 3.13.0-107-generic kernel, v4.9.0-HBase-0.98
> Reporter: Rahul Shrivastava

> 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.
