Thanks for both of suggestion.
Unfortunately we will not get sign off on installing the SDK - due to change control.
I was aware of the "Administration > Front-End Servers" - I guess I was looking for something lil more automated.
Especially as we are multi tenanted environment .
Once again I like the DBA idea means logging 10s of DBA boxes would not be the easiest way to do this.
As I have a list of all the Outsystems front end nodes - I was hoping I do a while loop through a file containing all the hosts , then I would be able to grep or cat a particular file to find out if it were dev/test/prod.
In the end I was able to get the networking team to grep for dev/test/prod on the VIP name of the front end nodes.
Not perfect but it has worked for now :-)
