> Support filters in ozone insight point
> --------------------------------------
>                 Key: HDDS-2071
>                 URL: https://issues.apache.org/jira/browse/HDDS-2071
>             Project: Hadoop Distributed Data Store
>          Issue Type: Sub-task
>            Reporter: Marton Elek
>            Assignee: Marton Elek
>            Priority: Major
> With Ozone insight we can print out all the logs / metrics of one specific component
s (eg. scm.node-manager or scm.node-manager).
> It would be great to support additional filtering capabilities where the output is filtered
based on specific keys.
> For example to print out all of the logs related to one datanode or related to one type
of RPC request.
> Filter should be a key value map (eg. --filter datanode=sjdhfhf,rpc=createChunk) which
can be defined in the ozone insight CLI.
> As we have no option to add additional tags to the logs (it may be supported by log4j2
but not with slf4k), the first implementation can be implemented by pattern matching.
> For example in SCMNodeManager.processNodeReport contains trace/debug logs which includes
the " [datanode={}]" part. This formatting convention can be used to print out the only the
related information.
