edgerouter-exporter

A Prometheus exporter for EdgeRouter BGP, DDNS, Load Balancers, and PPPoE sessions

Requirements

For development, the following dependencies are required:

In order to build the artifact, use cross build. To find on which architecture your model is running, refer to EdgeRouter - Hardware Offloading.

MediaTek-based devices

$ cross build --release --target=mipsel-unknown-linux-gnu

Cavium-based devices

$ cross build --release --target=mips-unknown-linux-gnu

Installation

Download the latest version of edgerouter-exporter and move it to the directory where it persists after the EdgeOS upgrades. Note that the root permission is required because it internally calls ubnt_vtysh.

To find on which architecture your model is running, refer to EdgeRouter - Hardware Offloading.

MediaTek-based devices

$ curl -fLO https://github.com/chitoku-k/edgerouter-exporter/releases/latest/download/prometheus-edgerouter-exporter_mipsel.deb
$ sudo mkdir -p /config/data/firstboot/install-packages
$ sudo mv prometheus-edgerouter-exporter_mipsel.deb /config/data/firstboot/install-packages
$ sudo dpkg -i /config/data/firstboot/install-packages/prometheus-edgerouter-exporter_mipsel.deb

Cavium-based devices

$ curl -fLO https://github.com/chitoku-k/edgerouter-exporter/releases/latest/download/prometheus-edgerouter-exporter_mips.deb
$ sudo mkdir -p /config/data/firstboot/install-packages
$ sudo mv prometheus-edgerouter-exporter_mips.deb /config/data/firstboot/install-packages
$ sudo dpkg -i /config/data/firstboot/install-packages/prometheus-edgerouter-exporter_mips.deb

Configuration

Environment variables

Configure by creating /config/user-data/edgerouter-exporter.env.

# Log level (optional; one of trace, debug, info, warn, and error)
#LOG_LEVEL=info

# Port number (required)
PORT=8080

# TLS certificate and private key (optional; if not specified, exporter is served over HTTP)
#TLS_CERT=/path/to/tls/cert
#TLS_KEY=/path/to/tls/key

# Path to Unix socket for VICI (optional)
#VICI_PATH=/run/charon.vici

# Op command (optional)
#IP_COMMAND=/bin/ip
#OP_COMMAND=/opt/vyatta/bin/vyatta-op-cmd-wrapper
#OP_DDNS_COMMAND=/opt/vyatta/bin/sudo-users/vyatta-op-dynamic-dns.pl
#VTYSH_COMMAND=/opt/vyatta/sbin/ubnt_vtysh

Command-line options

The command-line options that are equivalent to the environment variables above can be specified by lowercasing option and replacing underscores (_) with hyphens (-). For instance, LOG_LEVEL is equivalent to --log-level.

Usage

$ sudo systemctl enable --now prometheus-edgerouter-exporter.service
