This number should be between 500-1000 on a healthy cluster. I've seen this as high as 4.8 million before (roughly 50% of the data stored on the cluster ended up being osdmaps!)
Yes, ours is and has been healthy for a while... but we didn't start monitoring it until a few months ago, so it may relate to those slower startups.
This appears to be a bug that should be fixed in the latest releases of Ceph (Quincy 17.2.8 & Reef 18.2.4) based on this report:
Thanks, good to know! We'll get to 17.2.8 in the next couple of weeks, then 18.x later this year.
