> Key: HDDS-3236
> URL: https://issues.apache.org/jira/browse/HDDS-3236
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Reporter: Marton Elek

> Priority: Major
> Labels: pull-request-available
>
> Ratis use dropwizard metrics where the key parameters of the metrics (like group name or instance id) are part of the name of the metrics instead of using a tag.
> For example
> {code:java}
> ratis.log_appender.851cb00a-af97-455a-b079-d94a77d2a936@group-C14654DE8C2C.follower_65f881ea-8794-403d-be77-a030ed79c341_match_index {code}
> Instead of
> {code:java}
> ratis.log_appender_match_index{group="group-C14654DE8C2C",...} {code}
> It makes hard to combine the same metrics (match_index) from different sources.
> HDDS-2950 implemented a regexp based workaround, but the regexp doesn't match for the latest Ratis metrics.
