Determing why a server becomes unresponsive

We run all RHL 7.2 servers. Every now and then, we server becomes unresponsive to http, ftp and telnet. We can ping/tracert the machine and get normal response times.

My guess is is "something" is consuming the resources...

My question is, how can you determine what that "something" is? Is there a useful log file that may say something. I try the messages log file, and nothing real useful is in there.

Or better yet, how to monitor the server and prevent/notify that this "something" is causing issues....

Get's real anonying getting waken up at 4:00 AM to resolve a down server issue Determing why a server becomes unresponsive Why don't they ever go down at 4:00 PM when a person is up and awak Determing why a server becomes unresponsive
