Linux based monitoring solutions
Let's assume you are given a Windows network to monitor. Exchange, SQL, File, Web, etc.
You want to monitor event logs, system status, available disk space, security, etc, etc. Preferably with filters, e-mail/pager alerts, reports etc etc.since you won't have time to go read logs.
You want to spend $0 but you don't want to have to spend all your free time learning how to reinvent the wheel.
Which products would you use, running on which distro?
