> Key: IGNITE-16832
> URL: https://issues.apache.org/jira/browse/IGNITE-16832
> Project: Ignite
> Issue Type: Bug
> Reporter: Stanislav Lukyanov
> Priority: Major
>
> It would be useful to have a number of lost partitions of a cache as a
> metric. That way monitoring tools can be set up to fire an alert when there
> are lost partitions.
> For the record, there is a metric MinimumNumberOfPartitionCopies which kinda
> helps with that but 1) no one will ever look for it to monitor lost
> partitions 2) number of lost partition would be useful (and this metric only
> shows the fact that there are some lost partitions) 3) this metric doesn't
> seem to work on inactive cluster, topology changes, etc.
