Jitsi Prometheus exporter

Exporter that grabs various metrics from Jitsi, especially form the video bridges, and publishes them as Prometheus metrics. The basic idea is to enter the jvbbrewery MUC room and listen to the presence broadcasts from the JVBs.

There is a documentation of the published statistics by the video bridges.

Run

There are multiple ways to run the exporter. Once it is running, it will publish the collected metrics on :8080/metrics.

Register user in prosody

You will have to create a XMPP user in Prosody, do this with:

prosodyctl --config <abs path to jitsi-meet.cfg.lua> register <user> <auth-domain> <password>

If you are creating this user on the default domain, make sure you add it to auth domain @auth.jitsi.meet and not @jitsi.meet. Since the domain @jitsi.meet defaults to anonymous auth, this addition will not be successful.

Binary

Copy the exporter directory into your $GOPATH/src/ directory. In the newly created exporter directroy run go get ./..., then go build ./..., then go install ./... which then creates the exporter binary in $GOPTAH/bin/. You can run this binary, it will still pull its configuration (see below) from the environment.

Docker container

There is an image available on docker hub karrieretutor/jitsi:prom-exporter-latest. Alternatively build it yourself with the provided dockerfile. The configuration is provided via environment (see below). By running it as a docker container you gain the advantage of choosing the port which is used for publishing the metrics, see docker cli reference.

env configuration

env	description	default value
XMPP_USER	xmpp user for authentication
XMPP_PW	xmpp password for authentication
XMPP_AUTH_DOMAIN	xmpp domain to authenticate against
XMPP_SERVER	xmpp server host name
XMPP_PORT	xmpp port to use	5222
JVB_BREWERY_MUC	name of jvbbrewery MUC room to join; it will join with prom-exporter as nickname -> JVB_BREWERY_MUC@INTERNAL_MUC_DOMAIN/prom-exporter	jvbbrewery
XMPP_INTERNAL_MUC_DOMAIN	internal muc domain (this is where the jvbbrewery muc resides)
JVB_METRIC_SUBSYSTEM	Allows you to customize the metric names: [<subsystem>_][<namespace>_]metricname; both are optional
JVB_METRIC_NAMESPACE	see JVB_METRIC_SUBSYSTEM

XMPP_USER and XMPP_AUTH_DOMAIN are used to construct the JID XMPP_USER@XMPP_AUTH_DOMAIN
