Hi. I have tried to look through all your articles re the REST API but my understanding is that this can only be used if I write an EXE to connect to PRTG to access monitoring information.
What I want is vice-versa. I'm a .NET developer and I would like to build a Web Service that returns something. To keep the example simple let's say I want to create a web service that returns a True or False depending on some business logic during the day. I would like PRTG to connect and communicates with this web service and if it receives a FALSE it will display that as an "ERROR". Hence, during the day the PRTG server would poll my application at different intervals and if it receives an error it will raise the alert.
The example above is quite trivial, but on more complex scenarios I could return a list of error codes or numbers or a percentage. The more flexible the better!
