> Idea proposed by [~swagle]: Right now debugging quorum issues and lagging followers requires filtering logs on all 3 members. It would be easier if there was a command that could be sent from the CLI to get information from all members. This could include:
> * commit index
> * apply index
> * snapshot index
> * current term
> * group membership (as defined in raft-meta.conf)
> * Known leader
> * Known follower's commit indices if leader
> This could be implemented from the [ratis shell|https://github.com/apache/ratis/blob/master/ratis-docs/src/site/markdown/cli.md], but it may be easier for users if it is packaged within the ozone CLI under {{ozone debug}}. One challenge may be getting results from all nodes, since right now ozone client only communicates with the leader of the quorum.
