Added documentation for the new -U option, and did some cleanups.
FYI,
a few *tiny* issues.
-d eg: /dev/hda1 might be better than /dev/hda/, and drop trailing slash.
-m, -M. log-file not required.
-N path can be /absolute too, not just ../relative
-p 'cmd' no longer run between latencies, just before & after
pass-thru:
-s -T 10 -q the 10 is now 120.
more subtly - your intro doesnt express the defaulting behavior that
this section does describe.
any pass-thru provided with turn off those defaults, so if you just use
-h, the test will output lines
each second, and never finish, so you dont get histogram (IIRC - you may
get it from ^C handler).
Im not at all sure its worth touching, and I should probably change the
defaults to add histogram,
and drop quiet.
-h implies -s (its just easier that way)
-- needed by testsuite/*/run scripts, not by xeno-test. I dont recall
every using it.
BUGS
-N name is timestamped, giving uniqueness. This is a caveat, not a bug
-p oops. Im open to suggestions whether this is worth fixing.
(workload mgmt)
workload tasks arent always (ever?) restarted once they finish,
so a real /dev/hda1 workload may end before your test does, causing
non-uniform &
unexpected load variations.
workloads arent always killed if test is interrupted.
thanks,
