Remote monitoring

A thing has been exercising my nocturnal wakefulnesses.

I have strong monitoring systems on the datacentre servers.

I get all the usual goodnesses:

  • Uptime
  • CPU Load/Utilisation
  • Real Memory Utilisation
  • Virtual Memory Utilisation
  • Local Disk Space Used/Free
  • Disk IO Reads/Writes
  • CPU IO Reads/Writes
  • Swap Space Free/Used

But despite these things, I’m looking for another tool for my monitoring armoury.

What I want is an email (or SMS) sent to me if certain conditions are encountered by an external monitoring server (a monitoring server outside of my WAN).

There are a number of paid monitoring services who will do this, but I don’t want to rely on anyone else (also, I don’t want to pay anyone for this, when I have it within my own infrastructure capacity).

I just need to figure out the best way to make it happen.
