[ceph-users] Metrics for multi-site sync delay?

Hi, The RGW Sync Overview dashboard has graphs for replication (objects and byes/s) from source, polling request latency, and unsuccessful object replications. But it doesn't have anything like "age of oldest incremental change not applied". i.e. if I do radosgw-admin sync status and replication is not fully caught up, I get lines like: data is behind on 1 shards oldest incremental change not applied: 2026-01-19T13:51:27.418794+0000 [39] but neither is graphed (or maybe even in the output metrics). Is there a handy way of getting these in machine-readable manner? We're thinking we might want to e.g. alert on a high number of behind shards and/or the age of the oldest not applied change. We run Reef / Cephadm. Thanks, Matthew
