[jira] [Created] (FLINK-12423) Add Timer metric type for
flink-metrics module
Armstrong Nova created FLINK-12423:
--------------------------------------
Summary: Add Timer metric type for flink-metrics module
Key: FLINK-12423
URL: https://issues.apache.org/jira/browse/FLINK-12423
Project: Flink
Issue Type: Improvement
Components: Runtime / Metrics
Reporter: Armstrong Nova
Assignee: Armstrong Nova
Hi guys,
Currently, Flink only support 4 registering metrics, {{Counters}}, {{Gauges}}, {{Histograms}} and {{Meters}}. If we want to measure the time cost metric, for example P75th, P99th, P999th, right now can only use Histograms metric. But Histograms metric not support TimeUnit type (second, millisecond, microsecond, nanosecond). So it's not convenient to collaborate with outside metric system.
The Codahale/DropWizard support Time meter, so we can wrap it in Flink.
Thanks for your time.
