Hi
I'm running latest Ceph Pacific 16.2.13 with Cephfs. I need to collect
performance stats per client, but getting empty list without any numbers
I even run dd on client against mounted ceph fs, but output is only
like this:
#> ceph fs perf stats 0 4638 192.168.121.1
{"version": 2, "global_counters": ["cap_hit", "read_latency",
"write_latency", "metadata_latency", "dentry_lease", "opened_files",
"pinned_icaps", "
opened_inodes", "read_io_sizes", "write_io_sizes", "avg_read_latency",
"stdev_read_latency", "avg_write_latency", "stdev_write_latency",
"avg_metada
ta_latency", "stdev_metadata_latency"], "counters": [],
"client_metadata": {}, "global_metrics": {}, "metrics":
{"delayed_ranks": []}}
Do I need to set some extra options?
Were you using the ceph-fuse/libcephfs user space clients ? if so you
need to manually enable the 'client_collect_and_send_global_metrics'
option, which is disabled in Ceph Pacific 16.2.13.
While if you were using the kclient you need to make sure the
'disable_send_metrics' module parameter is 'false' for ceph.ko module.
