For free

The miServer App lets you configure up to 5 single checks for free which will be processed in a 15 minute interval each.

This allows you to monitor at least one typical internet-presence. You can check DNS, Mail and Web for one domains - and still have 2 checks left that can be used for an additional URL or a ping-test.

You may increase the number of checks and their frequency by purchasing a subscription from within the App.
