FreeSWITCH Exporter for Prometheus

Getting Started

Pre-built static binaries are available in releases.

To run it:

./freeswitch_exporter [flags]

Help on flags:

./freeswitch_exporter --help
usage: freeswitch_exporter [<flags>]

Flags:
      --help                   Show context-sensitive help.
  -l, --web.listen-address=":9282"
                               Address to listen on for web interface and telemetry.
      --web.telemetry-path="/metrics"
                               Path under which to expose metrics.
  -u, --freeswitch.scrape-uri="tcp://localhost:8021"
                               URI on which to scrape freeswitch. E.g.
                               "tcp://localhost:8021"
  -t, --freeswitch.timeout=5s  Timeout for trying to get stats from freeswitch.
  -P, --freeswitch.password="ClueCon"
                               Password for freeswitch event socket.
      --web.config=""          [EXPERIMENTAL] Path to config yaml file that can
                               enable TLS or authentication.
      --version                Show application version.

Usage

Make sure mod_event_socket is enabled on your FreeSWITCH instance. The default mod_event_socket configuration binds to :: (i.e., to listen to connections from any host), which will work on IPv4 or IPv6.

You can specify the scrape URI with the --freeswitch.scrape-uri flag. Example:

./freeswitch_exporter -u "tcp://localhost:8021" Also, you need to make sure that the exporter will be allowed by the ACL (if any), and that the password matches.

basic auth

build password

htpasswd -n BC 12 '' |tr -d ':\n'

Creating config.yml Let's create a config.yml file (documentation), with the following content:

basic_auth_users:
    prometheus: $2a$12$rcRim06GJMX3WUOTDXa.AOwvpWdy.Mrq2nR0Dgo53Zt0bSLpP.byy

confg.yaml file password is prometheus

You can validate that file with promtool check web-config config.yml

$ promtool check web-config config.yml
config.yml SUCCESS

You can add multiple users to the file.

TLS

Metrics

The exporter will try to fetch values from the following commands:

api show calls count: Calls count api uptime s: Uptime api strepoch: Time synced with system status sofia xmlstatus gateway: fetch all gateway module: usage module.conf.xml fetch all module status api show endpoint all used endpoint api show codec all used codec List of exposed metrics:
