nfsiostat: display NFS RPC queue time for mountstats and nfs-iostat

2017-10-30T15:19:37+00:00

Display the NFS queue statistics for mountstats and nfsiostat
exported in /proc/self/mountstats. The RTT and total execution
time is currently displayed but it's also useful displaying
how long the task was queued for too

nfsiostat: avoid parsing "no device mounted ..." line

2017-10-05T14:47:39+00:00

Present nfsiostat includes the "no device mounted ..." line from
/proc/self/mountstats as addition description of the preceding mount
point. If the preceding mount point is NFS mountpoint, nfsiostat fails
to parse this line eventually. This patch avoids parsing this line.

tools: use install -m instead of --mode

2014-03-11T18:05:35+00:00

Use install -m instead of--mode for better compatibility.
E.g. busybox's install doesn't support the long option.

nfsiostat: periodically flush stdout

2013-09-18T19:10:26+00:00

In a shell script, when nfsiostat is run in the background with
stdout redirected to a file, flush stdout periodically to ensure
that we do not lose the buffered output if the nfsiostat process
is killed.

Recent changes to support python 3 changed the output of nfsiostat from:

avg RTT (ms)    avg exe (ms)

177.160         184.833
...

to:

read:
  ops/s		   kB/s		  kB/op		retrans		avg RTT (ms)	avg exe
