I've just discovered ipmitool - very cool stuff - and an fact running it from a perl script from which I want to sample fans and temps. I saw some earlier notes suggesting a more powerful perl interface to get better performance, but when I tried to download it I got stuck in 'rpm dependency hell' and decided I'd just stick to ipmitool as it feels like it's overhead is pretty low. I fact, running it 10 time showed me:
[EMAIL PROTECTED] SPECS]# time for i in `seq 1 10`; do ipmitool sdr> /dev/null; done; real 0m25.067s user 0m0.010s sys 0m0.080s and at < .1 second of cpu time I'm more than pleased. My thought was to take samples somewhere from every 1 to 5 minutes depending on how much accuracy I want, but I don't think I'd need more than that, so I can see running it anywhere from 300-1440 times a day. However the part that gets my attention is the elapsed time! I want to run this from a script that is doing other things as well, at a higher frequency and don't want to get bogged down with long delays and so that leads me to a couple of questions: - is it possible for ipmitool to hang or will it eventually time out if it has problems? if so, what if the timeout set to and is it possible to set your own? - is there a 'reasonable' amount of time to give it and then just abort it if it doesn't return? The reason I ask is if I run this from a perl script I could always set my own timer and just kill ipmitool it if it's taking too long - is it possible to speed up ipmitool by asking for less data? I saw an option to get by type, but only 1 type. I don't suppose there's a way to specify a list of things to get is there - I didn't see any references to such a capability in the man page. I don't think I'd want to call it more than once per monitoring cycle. -mark ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
