Hi ssvv,
Thanks for posting!
A couple of ideas for you here:
Firstly - you could 'ping' a web service by using the Download tool and retrieving/parsing the Download Headers field?
Secondly - you could write a really simple batch file that pings the services you're interested in (e.g. ping localhost/gallery) and then pipe the results to a text file which can be ingested back into Alteryx (attaching a really simple example to this post). All of this can be done using the Run Command tool.
I have a Ping_Batch_Command.bat file that contains a single line:
ping localhost
Let me know how you get on?
Cheers,
Nick
