Sonus Exporter for Prometheus

The Sonus Exporter is a Golang-based project that implements the multi-target exporter pattern and exposes metrics for a Ribbon SBC (Session Border Controller) in a format that can be scraped by Prometheus.

This version works with SBC v11.1+ utilizing the new RESTCONF API

Features

• Multi-target exporter pattern: Can scrape metrics from multiple SBC instances.
• Exposes metrics in Prometheus format for easy ingestion by Prometheus.
• Can be easily integrated into a Prometheus-based monitoring system.

Requirements

• Golang 1.16 or higher
• Ribbon SBC

Scaling

A single instance of sonus_exporter can be run for thousands of devices.

Usage

Installation

Binaries can be downloaded from the Github releases page and need no special installation.

We also provide a sample systemd unit file.

Running

Start sonus_exporter as a daemon or from CLI:

./sonus_exporter

Visit http://localhost:9700/probe?target=1.2.3.4 where 1.2.3.4 is the IP or FQDN of the sonus device from which to get metrics.

Configuration

The default configuration file name is sonus.yml (currently unused).

The username/password used to connect to the SBCs is configured via the SONUS_USER and SONUS_PASSWORD environment variables. The same username/password combination is used for all target SBCs.

Prometheus Configuration

target can be passed as a parameter through relabelling.

Example config:

scrape_configs:
  - job_name: 'sonus'
    static_configs:
      - targets:
        - 192.168.1.2  # sonus device.
        - sbc.local # sonus device.
    metrics_path: /probe
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 127.0.0.1:9700  # The sonus exporter's real hostname:port.

Similarly to blackbox_exporter, sonus_exporter is meant to run on a few central machines and can be thought of like a "Prometheus proxy".

TLS and basic authentication

The sonus Exporter supports TLS and basic authentication. This enables better control of the various HTTP endpoints.

To use TLS and/or basic authentication, you need to pass a configuration file using the --web.config.file parameter. The format of the file is described in the exporter-toolkit repository.

Note that the TLS and basic authentication settings affect all HTTP endpoints: /metrics for scraping, /sonus for scraping sonus devices, and the web UI.
