Subject [jira] [Commented] (IGNITE-7967) DataRegionMetrics#totalAllocatedPages is invalid if metrics were enabled at runtime
Date Wed, 18 Jul 2018 18:29:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-7967?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16548224#comment-16548224

Andrey Gura commented on IGNITE-7967:
-------------------------------------

[~cyberdemon] I've looked to your change and I believe it is very complex solution for this
issue. I believe that the simplest way to solve problem is just always count allocated pages.
Just ignore {{metricsEnabled}} flag.

> {{totalAllocatedPages}} is updated during runtime via callback. When metrics are enabled
at runtime, some pages may be already allocated, thus the metric shows invalid value.
