Jicofo stats - conference/participant = 1 when no conference is started

[pandel]

Hi!

My Jicofo version: 1.0-832-1 (Octo enabled, two bridges)

When no conference is running, the REST stats endpoint reports wrong counts for conferences and participants

root@aee438f1cacc:/# curl localhost:8888/stats
{"xmpp_service":{"total_recv":99650,"total_sent":61301},"jibri_detector":{"count":0,"available":0},"largest_conference":1,"conference_sizes":[0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],"total_conferences_created":17,"threads":225,"xmpp":{"total_recv":99650,"total_sent":61301},"jingle":{"received":{"source-add":1,"transport-info":45,"session-accept":36},"sent":{"session-initiate":36,"source-add":60,"session-terminate":2}},"bridge_failures":{"participants_moved":0,"bridges_removed":0},"avg_allocate_channels_req_time_nanos":0.0,"total_participants":42,"participant_notifications":{"ice_failed":0,"request_restart":0},"queues":{"jibri-iq-queue":{"added_packets":0,"removed_packets":0,"dropped_packets":0,"queue_size_at_remove":{"average_queue_size_at_remove":null,"max_queue_size_at_remove":0,"total_value":0,"total_count":0,"buckets":{"<= 0":0,"<= 1":0,"<= 4":0,"<= 16":0,"<= 64":0,"<= 256":0,"<= 1024":0,"<= 4096":0,"<= 16384":0,"> 16384":0,"p99<=":-1,"p999<=":-1}}}},"jigasi":{},"bridge_selector":{"total_least_loaded_in_region":0,"total_split_due_to_load":0,"lost_bridges":2,"total_not_loaded_in_region_in_conference":0,"in_shutdown_bridge_count":0,"total_least_loaded_in_region_in_conference":0,"total_not_loaded_in_region":0,"total_split_due_to_region":0,"bridge_count":2,"operational_bridge_count":2,"total_least_loaded_in_conference":0,"total_least_loaded":0},"jibri":{"total_sip_call_failures":0,"live_streaming_pending":0,"recording_pending":0,"live_streaming_active":0,"total_recording_failures":0,"sip_call_pending":0,"sip_call_active":0,"total_live_streaming_failures":0,"recording_active":0},"conferences":1,"participants":1,"slow_health_check":0}

That seems as a bug to me, but I am not able to analyze the code to understand what is going on here.

This is expected if you have a tab open with a single participant (there's no conference running, but jicofo has a conference object with one participant).

I did not have any tab opened at that time and after I restarted Jicofo everything seemed to be correct.

Is there any way to find out more about this single conference/participant? I tried to find some information via the log, but there is simply too much data inside the log and I don't really know how to filter it to narrow it down.

[bgrozev]

Since version 840 you can query /debug and /debug/conference/<CONFERENCE_ID> to get more info.

It could have been a conference that wasn't cleaned yet (the timeout is 20 seconds), or some sort of leak. If you share some logs I can take a look (you can remove personal info and/or email support at jitsi dot org)

Many thanks for the info! I am on 832 (stable Debian 11) right now. If I get to 840, I'll give it a try!
