Subject [jira] [Updated] (FLINK-12423) Add Timer metric type for flink-metrics module
Date Tue, 07 May 2019 06:49:01 GMT

     [ https://issues.apache.org/jira/browse/FLINK-12423?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Armstrong Nova updated FLINK-12423:
-----------------------------------
    Description: 
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. 

    Flink metrics doc [https://ci.apache.org/projects/flink/flink-docs-master/monitoring/metrics.html]
     Thanks for your time.
