Alexey Kuznetsov created IGNITE-1932:
----------------------------------------
Summary: Wrong value of BusyTimePercentage metric after
ignite.cluster().resetMetrics()
Key: IGNITE-1932
URL: https://issues.apache.org/jira/browse/IGNITE-1932
Project: Ignite
Issue Type: Bug
Components: compute
Affects Versions: ignite-1.4
Reporter: Alexey Kuznetsov
Assignee: Alexey Kuznetsov
Fix For: 1.5
I found that after call of
ignite.cluster().resetMetrics()
BusyTimePercentage became 100%
After some debug I found that BusyTimePercentage - calculated as:
1 - IdleTimePercentage
and IdleTimePercentage calculated as IdleTime / UpTime
and on reset we set IdleTime to 0.
So the possible fix is to preserve IdleTime on reset.
