junfei liang created PHOENIX-5717:
-------------------------------------
Summary: Phoenix Global Client Metrics are only increased In
QueryServer
Key: PHOENIX-5717
URL: https://issues.apache.org/jira/browse/PHOENIX-5717
Project: Phoenix
Issue Type: Improvement
Reporter: junfei liang
Attachments: phoenix-histogram-metric.patch
After PHOENIX-1819 Phoenix Client Metrics are added After PHOENIX-3655 PQS
Metics is exported to Hadoop-Metrics as Gauge Metrics.
However these metrics are increased only and never reset when export to
hadoop metirc system.
In our online cluster, QueryServer is deployed as a standalone process，when
exposed these metrics to ganglia, we found these metrics is never decreased.
We may change
org.apache.phoenix.monitoring.GlobalClientMetrics.PhoenixGlobalMetricGauge#getValue
to use average value for metrics system, but it's no enough.
when talk about read/write stats, we also need TPS, RT( including avg, max,
min, 99th etc.), batch size.
So i think we can introduce Histogram Metric to our monitor system， See patch
for Mutation Metrics a example。
has any suggestions？
