Nagios on 64MB RAM?


#1

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:

Can Nagios be run with under 64mb ram? How would you recommend I do this? Thanks for any help :slight_smile:
