Check jitsi-videobridge-stats

Overview

Checks the number of participants on a Jitsi Videobridge (v2.1+) and returns a bunch of performance data using the REST version of the COLIBRI protocol.

The statistics are available through the /colibri/stats endpoint on the private REST interface that must be activated first.

The check does not convert the total values into discrete values. Instead, all totals are reported as „continous counters“, otherwise the duration of the conferences will not be displayed nicely on the timeline, for example.

For a discussion on how many users Jitsi support see here1, here2 and here3

Checks the number of participants on a Jitsi Videobridge and reports a bunch
of performance data.

optional arguments:
  -h, --help            show this help message and exit
  -V, --version         show program's version number and exit
  --always-ok           Always returns OK.
  -c CRIT, --critical CRIT
                        Set the CRIT threshold for the number of participants.
                        Default: >= 100
  -p PASSWORD, --password PASSWORD
                        Jitsi API password.
  --test TEST           For unit tests. Needs "path-to-stdout-file,path-to-
