[SuSE Linux] Linux and the CPU
Using the K desktop. After my SuSE has been up and running for a while on this Micron 166 (32mb ram) I get bogged down with memory usage. The HDD light remains on and the mouse gets choppy. I looked in with Xosview and can see my CPU running at 100teadily. A glance with top and I see something called "find" claiming 930f my CPU usage, so I kill it. Then "mandb" runs up to 78%. Kill that. Now things are good again. What was happening? I have only used Terminal, KMail and Netscape this morning on a fresh boot. I have a screensaver active, is that it? I just can't see the CPU remaining under a load after the screensaver stops. -- Steve Mills steve@millsphoto.com <A HREF="http://www.millsphoto.com"><A HREF="http://www.millsphoto.com</A">http://www.millsphoto.com</A</A>> Great wallpapers live here. - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e

Have you been working early today, say around 6:53 am? Then you have experienced the cron.daily cron job. This is a set of shell scripts, that do some background system maintenance, like removing old core files, rotating log files and updating the manual page index cache. Nothing to worry about.

That's exactly it. Thanks. Can I reschedule that job to allow my typical early morning browsing? I haven't dug that deep yet other than to know that cron is in here. And given that I have a rather minimal system on that Micron, the word "background" is hardly appropriate. :) -- Steve Mills steve@millsphoto.com <A HREF="http://www.millsphoto.com"><A HREF="http://www.millsphoto.com</A">http://www.millsphoto.com</A</A>> Great Wallpapers Live Here. - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e

have a look at /etc/crontab. I sheduled mine to 7:53 pm, cause that's the time the thing is on. # min hour 53 19 * * * root $HOME/bin/cron.daily have a look at the man-pages. there are a few examples in there.

I made a time change there (2:53 am) and now it waits until I have started using the machine, usually about 5 am. This is apparently due to having APM in place, thus it can't do any maintenance while the machine is in sleep mode. Is there a workaround for this?

I understand how to do that. I was hoping I could find a setting (similar to the one in....what's that thing called...oh yea..Windows) that would allow me to have the file servicing start during idle times of the computer, even during rest. I really don't want to give up power management. I'm sure it's something that a driver could be created for. I'm equally sure that's out of my league. :) Thanks, zens.

If it is an IDE HDD, then it is possible that there is a BIOS setting which puts the drive into standby/suspend mode. See if your BIOS allows to turn this feature OFF. Just a thought. Also, refer to hdparm. Some netizen from the comp.os.linux.* groups suggested to look into hdparm settings (search dejanews.com). I don't recall the exact details off hand. -- Arun Khan - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e

Just go into Yast and tell it NOT to start CRON at bootup, I never miss it on my personal system, and the system is running better. zentara - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e

Sounds like it's the whatis database builder. It should only take a few minutes to run. The database itself it somewhat important (it's used for the man -k, apropos, and whatis commands). -- Steve Philp sphilp@ameritech.net "The Internet is like crack for smart people" --Arsenio Hall - To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e
A good program to see what's running and using the most CPU time is "top". Also, there is a daily cron job that runs around 06:53 local time that does varies house keeping chores like removing core files, and rotating system log files. I didn't realize there was a daily cron job running until I noticed one morning when I walked into my den that my server's hard drive was thrashing away when no one was logged into the box doing anything.

What was happening? I have only used Terminal, KMail and Netscape this morning on a fresh boot. I have a screensaver active, is that it? I just can't see the CPU remaining under a load after the screensaver stops.

There really isn't a substitute for top, but a nice alternative to top for x is qps. It's on the S.u.S.E. discs. Tony Schlemmer wrote:

If you are using x try ktop (designed for kde but will run under any wm). It is like top, but with mouse support for all functions. Got an errant process? Just <click> and it's dead. It also has a process child thread tree. That is very usefull as well.
