[lustre-discuss] question about /proc/fs/lustre/mds/MDS/mdt/stats

[Mahmoud Hanafi]

Why is 'samples' the same for req_waittime, req_qepth, req_active, 
req_timeout all the same.

req_waittime              611801704 samples [usec] 3 5061774 
1257652419050 953071357361477866
req_qdepth                611801704 samples [reqs] 0 89 21110263 22332201
req_active                611801704 samples [reqs] 1 127 2647563677 
122463789917
req_timeout               611801704 samples [sec] 150 150 91770255600 
13765538340000
reqbuf_avail              1256133286 samples [bufs] 481 574 705260598158 
396165104527476
....

shouldn't the samples for [usec] be total usec similar to units of 
[bytes]. For example:
cat /proc/fs/lustre/obdfilter/nbp8-OST00d1/stats
snapshot_time             1474043858.153583 secs.usecs
read_bytes                21704638 samples [bytes] 4096 1048576 
12917847764992
write_bytes               25971348 samples [bytes] 1 1048576 19719890405713
....

Samples here is total bytes transferred correct?
