* nfsiostat: display NFS RPC queue time for mountstats and nfs-iostatRyan Doyle2017-10-302-3/+15
| | | | | | | | | 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 Signed-off-by: Steve Dickson <steved@redhat.com>
* nfsiostat: avoid parsing "no device mounted ..." lineManjunath Patil2017-10-051-0/+2
| | | | | | | | | | 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.

| | | | | | | | "nfs-iostat.py --attr" was displaying nonsense (like negative counts and percentages). Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Steve Dickson <steved@redhat.com>

* tools: use install -m instead of --modeAaro Koskinen2014-03-111-1/+1
| | | | | | | | Use install -m instead of--mode for better compatibility. E.g. busybox's install doesn't support the long option. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Signed-off-by: Steve Dickson <steved@redhat.com>
* nfs-iostat: Make Python 3 compatibleBohuslav Kabrda2013-09-181-11/+11

* nfsiostat: periodically flush stdoutHarshula Jayasuriya2013-09-181-0/+2
| | | | | | | | | | 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.

* nfsiostat: Breaks on 3.1 kernelsSteve Dickson2011-09-211-2/+9
| | | | | | | | | nfsiostat depend on all devices entries in /proc/self/mountstats to start with the word 'device'. With 3.1 kernels, NFS entries start with the actual device (i.e. server:/export) not the word 'device'. This change confused nfsiostat parsing. Signed-off-by: Steve Dickson <steved@redhat.com>

| | | | | | | | | | | | If I invoke the tool with an interval of 10 and a count of 2, it will: - show the summary - sleep 10s - show the stats for the last 10s - sleep 10s - exit Signed-off-by: David Lecorfe <dlecorfec@gmail.com> Signed-off-by: Steve Dickson <steved@redhat.com>
* nfs-iostat.py: divide by zero with fresh mountKevin Constantine2010-06-221-0/+6
| | | | | | | | | | When an export is freshly mounted, /proc/self/mountstats displays age = 0. This causes nfs-iostat.py to divide by zero throwing an error. When we have age = 0, other stats are greater than 0, so we'll set age = 1 and print the relevant stats.
