In the network monitor the worker hosts are listed, however, the names may, as in our case, be defined by the IT dep and as such cannot easily be deciphered. When a host is logged in, there should be a username connected to the host, so I would suggest the option at least of adding a column in the Worker status list that also shows the user. It is then easier to go to that user and ask them to maybe release a paused task or temporarily add more available cores to a long render session.
Thanks
