How to check and wait for available render nodes

[johnodd28]

Is there a command line way to check for "available" and "in use" render nodes?

I currently connect my nodes using: setvrlservice -server=MyLicesnseServerIP -port=30304
which connect fine but doesn't tell me how many render node licenses are available.
I then start my renders using: vray -sceneFile=... -frames=... etc
And some of them fails with: 31merror: Could not obtain a license (1002): All the licenses for this product are currently engaged.
because I'm obviously trying to start more jobs than the number of render node licenses available.

Is there a way to check before I call the vray command and to wait until a license becomes available?

Thanks!

You can monitor the status of your licenses on a machine, where V-Ray license server is installed and you open the web browser and type "localhost:30304". Typically this is the machine, where dongle or online based license is activated. All of the workstations and render slave machines pointing to this machine with its client license settings. If you are using only online based license, you can monitor the same web interface on any machine, because the online based licenses is updated immediatelly.

Thanks Stefan, I'm aware of the browser solution but that's not what I'm looking for. I'm scripting a fully automated pipeline. I have a Python script that spawn hundreds jobs at once and I'm looking for a batch command to query the status of my 10 render node licenses before rendering. I'm not the only person using the licenses so I don't always have the same number available. I want to queue my jobs while waiting for licenses to be released but I don't find any batch command to get a count on the available licenses.

Edit: Should I parse the webpage with a batch command? Or is there a better way?
