Smallest VPS to run Nagios?

How much RAM would I need to run a Nagios box that would check 4 hosts with about 3-5 checks per host?

I already have a setup in LA, but would like to add another node in the Midwest for redundancy. I did t want to pay too much, my LA node runs more than just Nagios so it has more RAM.

  • A 128MB might do fine if not 256MB.

    If you already have one set up and want another one, you can just do free -m on the existing one.

  • Nagios works fine on my 128MB box.

  • My Nagios runs just fine on a 128MB. I wouldn't recommend using Apache, but you should be able to get away with it.

  • I run mine on a 64m vps:
    root@mickey:~# free -m
    total used free shared buffers cached
    Mem: 64 44 19 0 0 32
    -/+ buffers/cache: 11 52
    Swap: 64 11 52

    That vps is running munin and nagios with nginx as the web server

  • 19mb spare @Holoshed -- Enough for a good MySQL setup, is it not? :)

    It all goes to show you do not always need as much ram for stuff as you think if you use the right alternatives like nginx instead of apache.

    I could use it for mysql but no need as I have plenty of other servers for that though.

  • I'm going to try for 64mb VPS if not 128 should be it. Thanks guys.

  • 128MB is fine if Xen, OpenVZ VPS with 256MB RAM should do the trick too. Also switch Apache to MPM Worker - using less RAM.
