commit 99af59eb2018f3fbe2080a5e783da88e9c44552f
Author: Mark Goodwin <mgoodwin@xxxxxxxxxx>
Date: Fri Jan 15 19:54:17 2016 +1100
qa: add an archive containing a mark record for qa tests.
The qa/archives/pmiostat_mark archive spans :
commencing Tue Dec 1 16:00:02.042 2015
ending Tue Dec 1 18:59:41.654 2015
and the mark record is about halfway thru at 17:50:02.041
Replaying from the beginning with -t 15m should return
PM_ERR_VALUE
at 18:00:02, i.e. when interpolating between the fetch at
17:45:02
and the fetch at 18:00:02.
...
Is the QA test to use this still in your pipeline?
yes, but it's basically your pmiostat invocation below.
I've been thinking about this (a lot) and believe I'm moving towards Frank's
point of view. I'll add the the BZ entry when the dust settles.
ok, that'll be an interesting read :)
My current code (running QA at the moment) produces this sort of output ...
pmiostat -a pmiostat_mark -t 15m -A 15m -z -x t
...

Is that more what you'd like to see?
yes - the NODATA is what I'm expecting. Current top-of-tree reports '?'
for sda (because the counter went backwards) and 0 for mmcblk0
(because there was no activity for that instance).
Thanks
