Thank you John for the feedback.
The mon and mgr output does not include the hostname either -- those are the daemon names. CephFS output also already includes the daemon name (mdss-0 in the example).
The explicit list of daemons in the CephFS output will probably have to be removed at some point, as systems with many MDSs become more common -- historically people have usually only had a few MDS daemons, but with containerisation and active-active CephFS the numbers will rise beyond what fits on one line. Similarly for RGW, I don't think we would want to add a list of daemons in ceph status, because they're potentially numerous.
Right. when running more than 5 yes it can cause ceph status to grow very big which I agree we do not want.
Commands like "ceph osd status" and "ceph fs status" are meant to provide friendly ways to see this kind of thing, and they should be enhanced if they're not doing the job well today -- it would also be nice to have a "ceph rgw status" that gave the detailed list of daemons too.
Yes, I think this would be great and we should make it as a standard and we should standardize our commands:
ceph <daemon-type> status
1. ceph osd status
2. ceph mon status <- at present - ceph mon stat
3. ceph mds status <-- at present - ceph fs status
4. ceph rgw status - not present
5. ceph rbd-mirror status - not present
Is the main missing piece here a friendly way of seeing the list of RGW daemons?
Yes. And I think ceph rgw status is a perfect fit.
