Hi,
I just setup a virtual one-node cluster (16.2.5) to check out
cephfs-top. Regarding the number of clients I was a little surprised,
too, in the first couple of minutes the number switched back and forth
between 0 and 1 although I had not connected any client yet. But after
a while the
Contradicting outputs, it seems immediate ones. You need to wait for a
few seconds for the 'perf stats' (and of-course the cephfs-top) to
display the correct the metrics. I hope you have ongoing IO while
running 'perf stats' and cephfs-top. What is your kernel version?

If I run the commands now, I still don't get any information returned with
ceph fs perf stats.
cephfs-top still says there is no cluster ceph.
The clients are all el7 & el8 kernel clients and show up in the Dashboard.
When I execute "ceph tell mds. client ls", I can see all clients
are there. For
Hi,
please find my 'client ls' output at the end.
I was quite patient, I waited for an hour or two, and tried it again
this morning. I copy a couple of GB into cephfs which takes quite a
while so there is something like a constant stream of data. This is
also visible in the daemonperf outp

Hi,
I just upgraded our cluster to pacific 16.2.5.
As I'm curious what cephfs-top could give for insights, I followed the
steps in the documentation.

Regarding: "Probably there is no IO"
When I check "ceph -s", it says there is activity. Not much, but some
activity:
io:
client: 316 KiB/s rd, 10 KiB/s wr, 1 op/s rd, 1 op/s wr
And no activity doesn't explain why cephfs-top complains about not finding
the cluster.
