Monitor perfromance
Hi,
I've launched a free service and would need to monitor the performance of my server so that I know when it is full.
Any good ideas?
When using top, what would be OK/HEAVY/BAD values of CPU? I only got a couple of hundred mb RAM left but I guess the rest is taken by idle apache daemons.

As I said, Fedora Cora 3. But please what I'm interested in is meassuring the performance.
Is there for example a way to see how many apache sessions that is alive and actually consuming RAM?
I'll be happy to discuss upgradding and patchnig afterwords.www.jinity.com - Start an internet community website for free

I believe Nagios (http://www.nagios.org) can be used to monitor the load on remote servers, and alert you to events such as low disk space, bad ping times, etc.
