I'd like to be able to query the license server before attempting to start a job. Many times I go to start a job via a build and it fails due to a lack of a license, I'd like to be able to query for ...
I like this idea as well and have run into this problem many times.
It would be great if Smartbear added an interface to TC scripting to query this properly.
However, a workaround is to directly access the license manager page e.g.
http://localhost:1947/_int_/sessions.html
Suck it in through TC and check how many sessions are active. It is a little tricky as if you have TC with Platform, Web and Desktop it will show an entry for each, but it should be easy to extrapolate from this.
