Hi, We are running a Solr Cloud setup in production with the following setup: 1. TLOG nodes: 3 2. Pull nodes: M (depending upon the read scalability that is needed)
Last week we encountered an issue where one of the pull replica wasn't able to fetch the index from the leader. While we are still in the RCA process, we wanted to find if a metric already exists under "/solr/admin/metrics" which can be used as a way to identify when the given core last synced up with the leader. This will massively help in improving our alerting setup and figure out stale nodes quickly. Apologies if such a question is already answered or the details already exist in the reference manual. If that is indeed the case, please drop the relevant link below. Regards 6harat
