What tool do you use to monitor your servers?
I want to monitor around 30-50 servers. This includes:
- Is MySQL running?
- Is Apache2 running?
- How high is the ping?
If any of the Services fail (not pingable, MySQL down, ...) i want to receive an email with a detailed status report.
I'd love to see a nice web interface, too :)
Further: I want the system to try to reboot the server (at the moment, when a server fails i have to reboot it manually).
Is this possible, if yes, how?
