------------------------------
Summary: Pre-check timespan in meterview to avoid NAN
Key: FLINK-10990
URL: https://issues.apache.org/jira/browse/FLINK-10990
Project: Flink
Issue Type: Bug
Components: Metrics
Affects Versions: 1.7.0
Reporter: aitozi
Assignee: aitozi
Fix For: 1.7.0
In the metric tool MeterView. If user use the meterview with the timespan
smaller than UPDATE_INTERVAL_SECONDS = 5 , the getRate will always return 0/0 =
NAN. And this is not friendly , I think we should pre-check it.
