this topic is not new but currently relevant. All related threads I’ve found refer to the muc_size module. IMHO, this module cannot be recommended. In particular, the module depends on obsolete ssl dev libraries. Additionally, the module cannot be used in an environment where users have to login to jitsi/prosody.
Alternatively, there are threads where the jitsi log data are used to obtain the mentioned statistic data. I’ve also gone this way. But in the current version, the jitsi logging has changed. The current log format does not allow obtaining room statistics from the logfile.
In particular, if a single user opens a room, the event can be found. But when this user leaves the room, the closing of the room cannot be determined.
Therefore, I want to ask for 2 things:
Is it possible to implement the room/participants statistics function directly in jitsi/prosody?
Use a log format where the room creation, joining/leaving of members and the room destroy can be found decidedly? (like in older versions of jitsi)
