   Without super deep consideration it makes sense. This page adds only high level information
about the state information. When it looks bad from high level then users are interested in
more granular information to find out the root cause. One step on this road could be to show
state information per state basis (not yet created a jira for this). When we added custom
metrics + watermark info we can do experiments what is the most valuable information to users
in finding out unhealthy query root causes.
