I am a developer that also has to monitor several things on different servers.
1) Did all of the MS SQL databases backup last night? 2) Did all of the MySQL databases backup last night? 3) Were the database dumps actually copied to the right folder? 4) How much free space is left on each server's hard drives? 5) How big are folders "abc", "def", "etc" getting? 6) Send emails/alerts when thresholds are reached
Just basically something to help me NOT forget such important things. I thought about writing something myself but didn't want to waste the effort if something is already out there.
I would also prefer one application instead of many if I could.
EDIT Forgot to mention the operating system. These run on Windows Server 2003 and/or 2008. In fact, what would be cool is a program that supports multiple servers from one machine. Something that can log into those servers.
