Hello I am a newbie to Nagios and linux in general. I have a small Debian Etch VPS that I’m using as a secondary DNS server. I’d like to setup Nagios so I can monitor a couple of websites (mostly blogs) and alert me via email if they go down.
Here’s the output of top showing my current resource use:
