i have a problem on one of my servers running ispconfig + debian etch.
suddenly it becomes very loaded:
top - 12:07:39 up 2 days, 13:59, 2 users, load average: 42.99, 44.59, 33.68
and the top processes are many many apaches and mysql.
my problem is that i can not figure out which site is causing the load. in the /var/log/apache2/access.log there is nothing important shown, because everything goes to /var/www/*/log/web.log, but its barely impossible to go trough every log because there are 400+ sites on the server
Any suggestion how i can figure out which site is causing the high load? tools, tips or tricks? Its very urgent and important
