I would like to acquire in a VI each time we launch a webservice.
For that I would like to read the url method each time we execute on a webpage.
Probably the information is inside the labview web service request but I don't know how to extract it.
i honestly do not understand your request.
A webservice is started with the application. Counting the number of starts of the webservice is similar to the question how often you start the application.
I assume that you want to know how often a specific function (method) of a webservice is called. If so, you have to implement a counter inside this specific method to keep track.
