A Prometheus exporter for EdgeRouter

edgerouter-exporter

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

Requirements

For development, the following dependencies are required:

• rustup (nightly toolchain is required for build-std)
• cross
• openssl (e.g. libssl-dev, openssl, or openssl-devel)

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.
