Re: CPU usage running mysql
Randy, I did not receive any replies so any suggestions would be useful!. We are using mysql with PHP and the problem may stem from PHP hogging the database, but I cannot be sure.

I wish it was! See my note below, the 7 box runs at about 0.5% but the 2.6 box runs at 99%!

Re: CPU usage running mysql
Hello again! Do you know if there is any way I can see what the mysqld is doing? If it is taking up 99% of the processor time, it is very busy doing something! I installed the binary version and consequently only have the tools available which came with that distribution.

Do you know if there is any way I can see what the mysqld is doing? If it is taking up 99% of the processor time, it is very busy doing something! I installed the binary version and consequently only have the tools available which came with that distribution. First of all, compare with supported tools such as vmstat or ps to ensure that top is correct. vmstat will not show the process itself but just total usertime, systemtime and idletime. You can also use Symbel ( www.setoolkit.com ), but I've experienced a bug in this too related to cpu/process info on Solaris 6, 7 and possible also 8. This is in all recent releases (3.0 - 3.2) and is present in toptool.se, aw.se and infotool.se. Tools in Symbel that will work and give you some info about mysqld is /opt/RICHPse/examples/pea.se this however tends to loop if you pipe the output to awk or another program. That's another bug ;-) For default debugging tools shipped with a standard Solaris go to /usr/proc/bin : # ls -al /usr/proc/bin total 30 drwxr-xr-x 2 root bin 512 Dec 31 20:25 . drwxr-xr-x 3 root bin 512 Dec 31 20:25 .. lrwxrwxrwx 1 root root 15 Dec 31 20:25 pcred - ../../bin/pcred lrwxrwxrwx 1 root root 16 Dec 31 20:25 pfiles - ../../bin/pfiles lrwxrwxrwx 1 root root 16 Dec 31 20:25 pflags - ../../bin/pflags lrwxrwxrwx 1 root root 14 Dec 31 20:25 pldd - ../../bin/pldd lrwxrwxrwx 1 root root 14 Dec 31 20:25 pmap - ../../bin/pmap lrwxrwxrwx 1 root root 14 Dec 31 20:25 prun - ../../bin/prun lrwxrwxrwx 1 root root 14 Dec 31 20:25 psig - ../../bin/psig lrwxrwxrwx 1 root root 16 Dec 31 20:25 pstack - ../../bin/pstack lrwxrwxrwx 1 root root 15 Dec 31 20:25 pstop - ../../bin/pstop lrwxrwxrwx 1 root root 15 Dec 31 20:25 ptime - ../../bin/ptime lrwxrwxrwx 1 root root 15 Dec 31 20:25 ptree - ../../bin/ptree lrwxrwxrwx 1 root root 15 Dec 31 20:25 pwait - ../../bin/pwait lrwxrwxrwx 1 root root 14 Dec 31 20:25 pwdx - ../../bin/pwdx There are man pages for all of them. They all give useful information about what a given process is doing. You can also use truss. ...ofcourse you can also get some info from MySQL itself with show processlist -- Un saludo / Venlig hilsen / Regards Jesper Frank Nemholt Unix System Manager Compaq Computer Corporation Phone : +34 699 419 171 E-Mail: [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?
