Hi!

Does anybody have some scripts to convert the output of the HP-UX (11.31) sar
command to gnuplot graphs? We have one machine that shows a severe performance
problem (e.g. top takes over 10 seconds to display the first page), and I'm
absolutely clueless what the problem is. It's not CPU; it might be I/O; it may
also be a kernel bug.

As I'm tight on spare time, some tools to adjust would help me writing
everything from scratch (I'd prefer using the sar/gnuplot approach to be able
to compare the results with other systems (like Linux)).

Regards,
Ulrich

Is this PA or IPF? If the latter, you can use free caliper on top.
And of course there is glance for both.

Yes, I saw caliper as part of the 11.31 Base_OE (IA64), but I'm afraid it takes
significant time to understand that tool set. Thanks for the hint.

If PA, then one might use Prospect:

One can also I suspect follow pointers from:

Modulo finding an "Up and running with Caliper in 30 seconds" writeup,
you could try a tusc trace of a top command, with the options to do
both syscall entry and exit tracing, with timestamps. That might
yield some interesting tidbits.

I've been reminded there is a FAQ off that link above. One that might
be of help for a first-time Caliper user is titled "I'm new to HP
Caliper. What's the first measurement I should take to start?"
