I was wondering how Cacti relates to Nagios. Do the both do the same job or compliment one-another?
In four words the post you're complaining about answered that question nicely.
I am a longtime user of cacti, and dealt with MRTG before then. Nagios is designed for simple on-off monitoring. It does this very well. If you need pager rotation schedules, nagios is prolly your best bet. I like wowing the executives with pretty color graphs, and that is a job for Cacti. You can visually see the impact on the system of jobs running on your MySQL servers. You can see when script kiddies attack your Apache hosts and then get blocked by your scripts. And it looks great printed full-page on the new color laser printer you should be taking advantage of. Unless you need something expressly wacky, or a difinitive pager rotation, cacti and related modules (thold) can monitor your whole computing environment, and page you when there are problems. I've had trouble handling cloud management, mostly due to new machines spawning, and old machines dying. I'm sure others have had similar issues. It is a pain to run scripts to add new hosts, and manage removing hosts that have been terminated.
