apache error logs

[kilburn]

Quote:Today our apache stopped working for some reason. i restarted the services and now it works. where are the ordinary apache error log file? mine is empty under /var/log/apache2/error.log, has ispCP an error log of its own? or where can find what happened to apache?

/var/log/apache2/users/default-error.log

Quote:Also i need to know if there is some kind of program like Nagios or something better that can notice me if apache is down?

As everyone has it's own preferences regarding monitoring, this is left to the user.
