## Intro ## Intro
A Prometheus exporter for [WireGuard](https://www.wireguard.com), written in Rust. This tool exports the `wg show all dump` results in a format that [Prometheus](https://prometheus.io/) can understand. The exporter is very light on your server resources, both in terms of memory and CPU usage. A Prometheus exporter for [WireGuard](https://www.wireguard.com), written in Rust. This tool exports the `wg show all dump` results in a format that [Prometheus](https://prometheus.io/) can understand. The exporter is very light on your server resources, both in terms of memory and CPU usage.
Starting from release [2.0.2](https://github.com/MindFlavor/prometheus_wireguard_exporter/releases/tag/2.0.2) this exporter supports IPv6 addressess too (thanks to [Maximilian Bosch](https://github.com/Ma27)'s PR [#5](https://github.com/MindFlavor/prometheus_wireguard_exporter/pull/5)). Starting from release [2.0.2](https://github.com/MindFlavor/prometheus_wireguard_exporter/releases/tag/2.0.2) this exporter supports IPv6 addressess too (thanks to [Maximilian Bosch](https://github.com/Ma27)'s PR [#5](https://github.com/MindFlavor/prometheus_wireguard_exporter/pull/5)).
From release [3.0.0](https://github.com/MindFlavor/prometheus_wireguard_exporter/releases/tag/3.0.0) the exporter allows two label modes: one is to dump every allowed ip in a single label (called `allowed_ips`) along with their subnets. The second one is to create a pair of labels for each allowed ip/subnet pair (called `allowed_ip_0`/`allowed_subnet_0`, `allowed_ip_1`/`allowed_subnet_1` and so on for every allowed ip). The default if the single label mode but you can enable the second mode by specifying the `-s` switch at startup. Thank you [Toon Schoenmakers](https://github.com/schoentoon) for this solution (see [https://github.com/MindFlavor/prometheus_wireguard_exporter/issues/8](https://github.com/MindFlavor/prometheus_wireguard_exporter/issues/8)).

In order for this to work, you need to add comments to your wireguard configuration file (below the `[Peer]` definition). The comment will be interpreted as `friendly_name` and added to the entry exported to Prometheus. Note that this is not a standard but, since it's a comment, will not interfere with WireGuard in any way. For example this is how you edit your WireGuard configuration file: In order for this to work, you need to add comments to your wireguard configuration file (below the `[Peer]` definition). The comment will be interpreted as `friendly_name` and added to the entry exported to Prometheus. Note that this is not a standard but, since it's a comment, will not interfere with WireGuard in any way. For example this is how you edit your WireGuard configuration file:

As you can see, all you need to do is to add the friendly name as comment (and enable the flag since this feature is opt-in). As you can see, all you need to do is to add the friendly name as comment (and enable the flag since this feature is opt-in).
