A thing has been exercising my nocturnal wakefulnesses.
I have strong monitoring systems on the datacentre servers.
I get all the usual goodnesses:
- 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.
