	# path_prefix = "/bigbluebutton"

	## Required BigBlueButton secret key
	secret_key = ""

	## Gather metrics by metadata
	# Using this option, gathering data will also insert metrics grouped by metadata configuration
	# gather_by_metadata = []

Metrics

• bigbluebutton:
  • fields:
    • meetings
    • participants
    • listener_participants
    • voice_participants
    • video_participants
    • active_recordings
    • recordings
    • published_recordings
    • online

Using the gather_by_metadata, plugin will add meetings and recordings metrics grouped by meetings provided metadata like the following:

tenant active_recordings=0i,listener_participants=0i,participants=0i,video_participants=0i,voice_participants=0i,meetings=1i 0

For example, using the following configuration:

## Gather metrics by metadata
# Using this option, gathering data will also insert metrics grouped by metadata configuration
gather_by_metadata = ["tenant"]

With a meeting:

<meeting>
	<meetingName>Meeting 2</meetingName>
	<meetingID>b0a78452-2266-4a0a-abae-8a016db8fccd</meetingID>
	<internalMeetingID>6e2f5787a62c9c3e13ee557c847decded4a53d59-1613138647914</internalMeetingID>
	<createTime>1613138647914</createTime>
	<createDate>Fri Feb 12 15:04:07 CET 2021</createDate>
	<voiceBridge>75042</voiceBridge>
	<dialNumber>613-555-1234</dialNumber>
	<attendeePW>e313fc20-2247-48dd-884a-b1cb48c7919c</attendeePW>
	<moderatorPW>be89c431-00d9-4e38-a2f9-c9a54c9873a3</moderatorPW>
	<running>true</running>
	<duration>0</duration>
	<hasUserJoined>true</hasUserJoined>
	<recording>false</recording>
	<hasBeenForciblyEnded>false</hasBeenForciblyEnded>
	<startTime>1613138647937</startTime>
	<endTime>0</endTime>
	<participantCount>5</participantCount>
	<listenerCount>3</listenerCount>
	<voiceParticipantCount>3</voiceParticipantCount>
	<videoCount>1</videoCount>
	<maxUsers>0</maxUsers>
	<moderatorCount>1</moderatorCount>
	<attendees>
	</attendees>
	<metadata>
		<tenant>localhost</tenant>
	</metadata>
	<isBreakout>false</isBreakout>
</meeting>

will generate the following metric:

tenant active_recordings=0i,listener_participants=3i,participants=5i,video_participants=1i,voice_participants=3i,meetings=1i,tenant=localhost 1617611008787972024

Example output

bigbluebutton meetings=0i,voice_participants=0i,recordings=0i,active_recordings=0i,participants=0i,listener_participants=0i,published_recordings=0i,online=1i,video_participants=0i 1673991941312623800
tenant voice_participants=0i,video_participants=0i,online=1i,meetings=1i,participants=0i,active_recordings=0i,listener_participants=0i,published_recordings=0i,recordings=0i,tenant=locahost 1673992041293464800
