Metrics and Phoenix

  Hello,
Im collecting metrics from region servers - readRequestCount/writeRequestCount.
The problem is that Phoenix SELECT is not affects readRequestCount/writeRequestCount.
Is this normal? If yes then which HBase metrics are affected by SELECT statements?

I think you want scan_next_rate for reads and mutate_rate for writes.
