Hey guys,

I noticed that my websites were inaccessible (ssh and mysql were working) so I quickly login, try the first thing that comes up: restart apache, and everything works fine again. Anyway, I don't know how to monitor this or rather: how to find out what went wrong...

Can anyone give me some pointers?

In the apache error log when restarting it I got. But that still doesn't indicate on what went wrong before to my apache choke.

thanks!

Did you check into

server reached MaxClients setting, consider raising the MaxClients setting

??


For monitoring there are many ways to do this... on the server itself... but I normally use cheap monitoring service that can do protocol testing. HTTP for example to check to see if a website is responding. If not, it pages me.

I use monitis.com for example. Up to 20 hosts (I set up SMTP, FTP and HTTP testing) configured for minimal services for ~$10 a month.
