> Project: Ambari
> Issue Type: Bug
> Components: ambari-metrics
> Affects Versions: 2.4.0
> Reporter: Aravindan Vijayan
> Assignee: Aravindan Vijayan
> Priority: Critical

> PROBLEM
> Negative values are being reported for IOPS in the "system servers" dashboard
> BUG
> This was a dockerized environment. Negative rate values were seen because
> read/write counters were dropping below the previous values at random times.
> On further investigation, it revealed that this was due to the docker volume
> groups present on the host. It is expected of docker containers to add/remove
> the volume groups during the lifecyle of a container. So, when a volume group
> goes away, the read/write counters do not contribute to the total counter
> values, thus making the value go below the last seen value.
> FIX
> Have a provision to discard such "special" disk partitions through a skip
> pattern. Individual disk counter metrics can be used to get disk specific
> counter values. If skipped, they will not contribute to the global counter
> metric.
