wgexporter

A very simple tool to expose information about specific Wireguard interfaces as Prometheus metrics.

Usage

wgexporter -i [ifname] -i [ifname]

Additionally, the following environment variables may be specified:

• METRICS_PORT - Expose Prometheus metrics on this port. Default: 9000.
• POLL_INTERVAL_MS - Poll interfaces for information every x milliseconds. Default: 1000.
• PING_TIMEOUT_MS - Timeout for tunnel/endpoint pings. Default: 1000.

You can run wgexporter in Docker or Kubernetes, but the container must either be run as --privileged or granted the NET_ADMIN capability, and must have access to the interface(s) you wish to monitor (e.g. by running on the host network).

For example:

docker run --cap-add NET_ADMIN --net=host ghcr.io/tehlordvortex/wgexporter -i wg0
