These are quite different, and I’m not sure which ones you want at globally vs at the conference level. Let’s look at them one-by-one:
conference ID: A list of conference IDs used to be available in /colibri/conferences, it is currently available under /debug
jvb ID: You could get this elsewhere, or you can use relay-id from /colibri/stats
region: Available in /colibri/stats
number of participants: We have the global in /colibri/stats and /metrics. For the conference level you can get it from /debug. I think you used to be able to get it by analizing the /colibri/conferences output, but not directly.
duration: this was never available from /colibri/conferences, but you should be able to get it from /debug (as creationTime)
bitrate and bytes transferred: /colibri/stats has the globals. We don’t have them at the conference level, but you can get them at the endpoint level from /debug. This was never exposed in /colibri/conferences.
CPU and RAM: we don’t expose these, you should get them from the OS. We do have stress_level though.
