Of which Munin is my favourite, very easy to install and start using. It comes loaded with all you want to know about your Linux system. But....
The only thing "wrong" with all of these products seems to be that it is YOU who needs to know WHAT is wrong.
I had a problem with a server and we were unable to find out why the server was performing slow. Once someone told me that a specific value needed not just to be "close to zero (0.01)" but "very close to zero (<0.001)" I was able to find out where the problem was.
I would have liked a product that would have warned me about that specific value instead of just showing a nice graph with lots of lines near zero. :-(
