current cpu usage
Ilya, sorry, I should have been more specific, I need to get the output in a format a script could use. I have tried the uptime command however I'm a bit lost at what the numbers displayed represent (& how to turn these into a percentage). (If indeed this is a good way to do this) Steve. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

cpu usage
Thanks for that, top -bin 1 seems to do the trick nicely, also found a bit of documentation at http://faq.mrtg.org/linux/proc-load.html that should let me do it without using top. Cheers.

Re: current cpu usage
> cat /proc/meminfo > cat /proc/loadavg The meminfo would help him but he posted that he didn't understand load average and, anyway, needs percent of CPU used. You can not calculate CPU usage from load average. You could use /proc to get CPU usage but it would be rather involved to do and why bother when the nice man who wrote top has already done it for you. :-) Pete -- http://www.elbnet.com ELB Internet Services, Inc.

I still don´t understand that completely ;-) And yep, that should´ve read cat /proc/stat instead.

Starving Student Needs Help
Hi I am a Canadian University Student. I was wondering, does anyone know where I can get a cheap connection to the Internet in Canada. I can use the school's internet service but it is choppy and expensive and to boot, waiting at the free kiosks are more trouble then it's worth. I can't use Bell's service because I can't afford it. I need the Internet to do school workHELP Starving Student -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]

(And no, I don´t know what the values in the first line > exactly mean, but as soon as I set up mrtg again, I´m gonna read up on > the kernel-sources) The problem with using /proc/stat is the values presented on the cpu line are running totals of jiffies spent in user, nice, system, and idle respectively. So, you have to read /proc/stat at least twice and then calculate the deltas (and average over the time delta if you seek an average. Reading man proc and the source code (proc_misc.c; function kstat_read_proc) helped a lot; man proc seems a bit out of date WRT 2.4.x kernels. Yesterday I wrote a perl script that does this (I'm playing with cricket ... see http://canaris.visionary.micromuse.com/cgi-bin/cricket/grapher.cgi?target=%2Fservers I'll make the script source available if someone wants it ... I use a db file to store the readings from each run for use in the next run. My loadavg figures come from /proc/loadavg ... I wasn't interested in any heavy lifting :) Now for the mem stats ... -- Nathan Norman - Staff Engineer | A good plan today is better Micromuse Ltd. | than a perfect plan tomorrow. mailto:[EMAIL PROTECTED] | -- Patton PGP signature
Re: Starving Student Needs Help
Hey, Try out 3webXS. You can register for it at http://www.get3web.com. I used to be a free 3web user and then I upgraded to XS. It's so much better. The ads are gone and so are the busy tones. I get on without a problem and never get booted off. When I upgraded, I spoke with an agent who assured me that the service was just as good as Sprint or Bell. I haven't been disappointed so far! I love it. Try it out, I am sure that you'd like it too! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
