Re: [PR] Add metrics for SEGMENTS_WITH_LESS_REPLICAS monitoring [pinot]

walterddr commented on PR #12336:
URL: https://github.com/apache/pinot/pull/12336#issuecomment-1928211216

   sounds good. so do we have
   - 0 : OFFLINE
   - 1 : ?? 
   - expected - 1 : SEGMENTS_WITH_LESS_REPLICAS
   - expected : HEALTHY
   
   am I correct?
   
   several questions
   1. how do we plan to avoid these alerts during say rebalance or server upgrade? (it will be one less during operation which might be a noise to monitoring system)
   2. do we want to address the naming of the "only 1 replica available, where configured to have more than 1" ?
   3. what if the RF is set to two? do we honor "only 1 replica" or "1 less replica" or both?
   
   (btw question 2/3 can be answered totally separate from this PR)
