Adding alert checkers:

• http://docs.observium.org/alerting_examples/
• http://www.maartenmoerman.nl/?p=612
• https://github.com/mgmoerman/docs/blob/master/observium-alert-checkers.md
• http://demo.observium.org/

Things to REMEMBER:

• Association, like in “device.device_id in” not something we can edit manually but gets generated when we do:
  • Alert Checker > device_down > Associations > Device in > Select all
  • ^^ We need to do this regularly to account for new or gone devices!
• In order to edit the “Entity Association Ruleset” access observium via managment address. If you access via public address, the menu appears empty!
