Hello, Interestingly, http://localhost:4040/metrics/json/ gives some numbers, but only a few which never seem to change during the application’s lifetime.
Either the web UI has some very strange limitations, or there are some URLs yet to be discovered that do something interesting.

They only exist for cluster master and worker. - Wonha On Wed, Sep 3, 2014 at 12:58 PM, Ruebenacker, Oliver A <oliver.ruebenac...@altisource.com<mailto:oliver.ruebenac...@altisource.com>> wrote: Hello, Thanks for the help! But I tried starting with “–master local[4]” and when I load http://localhost:4040/json I just get forwarded to http://localhost:4040/stages/, and it’s all human-readable HTML, no JSON.
