Dependency Example

For example: IPCheck Server Monitor is running on a server that is connected to the Internet via a DSL line. It monitors three sensors on a webserver in a commercial hosting center across this DSL line.

It is recommended to set up a PING sensor for a hop en route to the server (e.g. the first after the DSL line) with an interval of 15 seconds and a timeout of 5 seconds. This will be your dependency sensor.

Now you can set up e.g. the three sensors for the remote server (e.g. SMTP, POP3 and HTTP) with 60 seconds interval and the PING sensor created above as the dependency.

As soon as the PING sensor goes into WARNING or DOWN state, the monitoring for the webserver will be paused and will later be resumed when the PING sensor returns to UP status.

This is only a sample, for your configuration other concepts can be useful. You can use any type of sensor as the dependency sensor!
