Flexible server monitoring


The feature I really need - unless I'm just missing it? - is a way to model dependencies. The biggest case is that I don't want to get alerts for web sites I monitor when my home internet connection has a problem. In nagios I make external services dependent on my router ping, dns server ping, and check and I'd like to be able to do the same thing in Simon.

Re: Dependencies

Simon handles local internet outages automatically. Before each check, it checks that it can access one of two popular domains ( and, if I recall correctly), and if not, goes into an offline mode until the connection is restored.

You can disable this feature on a per-test basis via the checkbox to allow checking when offline (e.g. for local-only tests, or if you want to be alerted when your local internet is down).
