Number of clients currently streaming from MythTV

[nwuser]

Hi there,

My MythTV backend is running on a NUC and I want to shut it down in the case when there is no video being streamed out. I cant seem to figure the way to do it! I also need my SSH connections to not be trampled upon for which a "who" seems to help but I cant find a way out to determine if there are any clients currently streaming video from MythTV. Can someone suggest a way out? Thanks!
