for the tentacle release, "rgw_sync_delta" perf counters were added to track the "oldest incremental change not applied" in https://github.com/ceph/ceph/pull/61418. i don't believe they've been exposed by the dashboard yet On Mon, Jan 19, 2026 at 11:39 AM Matthew Vernon via ceph-users <ceph-users@ceph.io> wrote:

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,
