Simplomon could run a web server that expected periodic calls to certain url(s) and if they didn't happen periodically, an alert would be generated.
Then a server could be configured to run a curl command periodically, doing an HTTP GET for a certain url, and simplomon could throw an alert if this request wasn't seen within for instance 3x the configured expected periodic call times, indicating that the client was no longer able to perform these periodic call-ins.
Useful for devices that are behind a firewall and no direct connectivity can be achieved to the device from simplomon.
