Hi, for this purpose exist videobridge stats exposed as private REST API.
You can read docs here REST API and videobridge statistics

Hi,

I looked at thoses docs, and tried this :

apt-get install videobridge

edit /etc/jitsi/videobridge/sip-communicator.properties and added the lines :
org.jitsi.videobridge.rest.private.jetty.port=8080
org.jitsi.videobridge.STATISTICS_TRANSPORT=colibri
org.jitsi.videobridge.STATISTICS_INTERVAL=1000

service jitsi-videobridge restart

And still nothing on port 8080

nmap localhost
PORT STATE SERVICE
22/tcp open ssh
80/tcp open http
443/tcp open https
4444/tcp open krb524
4445/tcp open upnotifyp
5222/tcp open xmpp-client
5269/tcp open xmpp-server
5280/tcp open xmpp-bosh
8888/tcp open sun-answerbook

No 8080 !

What am i missing ?

Hello,

For activate the monitoring api in jvb =>
In jvb file “config” check this option :

JVB_OPTS="–apis=rest,xmpp"

balestra · April 1, 2020, 1:36pm

Hello,

I change the line JVB_OPTS in /etc/jitsi/videobridge/config and restarted jvb and videobridge service

Regards.

Re,

If Onpremise setup :
Check file /etc/jitsi/videobridge/config

If Docker Setup is more complexe but is not impossible :
Show Config in Container

docker exec -it [Contener JVB Name] cat /etc/jitsi/videobridge/config

balestra · April 1, 2020, 1:53pm

Hello,

I change the line JVB_OPTS in /etc/jitsi/videobridge/config and restarted jvb and videobridge service.

No response on port 8080 still

Regards.

Esteban135 · April 1, 2020, 1:56pm

In your /etc/jitsi/videobridge/sip-communicator.properties
Remove

org.jitsi.videobridge.rest.private.jetty.port=8080

Add

org.jitsi.videobridge.ENABLE_STATISTICS=true

balestra · April 1, 2020, 2:01pm

Done.

Was already in file.

Restarted jvb and videobridge service.

No response on port 8080 still.

THANKS FOR YOUR HELP !

Regards.

Please check yours configuration with one provided into REST documentation: https://github.com/jitsi/jitsi-videobridge/blob/master/doc/rest.md

Esteban135 · April 1, 2020, 2:05pm

You can publish your config file and log please ?

balestra · April 1, 2020, 2:24pm

OK. There was a typo in config.

Now port 8080 is open

But when i try to access from network, i get
Échec de la connexion sécurisée
Une erreur est survenue pendant une connexion à jitsi.i3s.unice.fr:8080. SSL a reçu un enregistrement qui dépasse la longueur maximale autorisée. Code d’erreur : SSL_ERROR_RX_RECORD_TOO_LONG

I didn’t configure private interface whith ssl
org.jitsi.videobridge.rest.private.jetty.tls.port=-1

Why does it want to do https and not http ?

Regards.

Hi,

Sorry for hijacking this thread, I wrote a netdata plugin specially for grabbing and displaying these jitsi statistics which might be interesting to you.

It is currently a work in progress but I plan to get it merged upstream in netdata later on.

Hi Francois,

I finaly succed with REST setup.

Thanks for your proposition, but the REST statistics are good for me.

Regards.

ronquilstr · April 3, 2020, 5:35pm

Hi @balestra
Can you tell us what was wrong in your config, and what finally solved the issue ?
It might help other people who fall in the same traps and find this topic using their favorite search engine.

balestra · April 6, 2020, 6:15am

HI,

I installed the jitsi-videobridge packet on ubuntu. It crached the original installation with jitsi-videobridge2 packet.

I rolled back to previous snapshot and the configuration described in this thread worked fine.

Regards.

haidlir · April 15, 2020, 4:39am

We already composed the TIG stack on top of docker for jitsi video bridge monitoring. Hopefully, it will be useful. Enjoy…

/usr/libexec/netdata/python.d/ don’t exist in Ubuntu 18.04.4 …

directory to use?

rkdeelip · May 18, 2020, 5:12am

You have to first install the netdata agent from https://app.netdata.cloud/
