# Prometheus Borg(Backup) exporter

Simple [Prometheus](https://prometheus.io/) exporter for [BorgBackup](https://www.borgbackup.org/).

Rewritten in go from https://code.recycled.cloud/RecycledCloud/prometheus-borgbackup-exporter.  
It has been rewritten mainly to enable building a static binary but also to support ipv6.
Additional features have also been added like `last_archive_time`.

## Building

To build, you'll need at least the [go toolchain](https://go.dev/doc/install) installed.
On Ubuntu you can generally have the latest version by running:

```sh
snap install go --classic
```

Then run:

```sh
go build
```

Note this executable is dynamically linked and not stripped.

### Static executable

To build a static executable, you'll need `make` installed. You can then simply run:

```sh
make
```
