# Borg exporter
|
||||
|
||||
Export borg information to prometheus. Extended to export information about a list of borg repositories (discovered via `find`), and also to export details about today's backups.
|
||||
Export borg information to prometheus.
|
||||
|
||||
## Dependencies
|
||||
|
||||
* [Dateutils](http://www.fresse.org/dateutils/) `sudo apt-get install dateutils`
|
||||
* [Dateutils](http://www.fresse.org/dateutils/)
|
||||
* Prometheus (obviously)
|
||||
* Node Exporter with textfile collector
|
||||
* [Borg](https://github.com/borgbackup/borg)
|
||||
* binutils (sed, grep, wc, etc)
|
||||
|
||||
## Install
|
||||
|
||||
### Manually
|
||||
Copy `borg_exporter.sh` to `/usr/local/bin`.
|
||||
|
||||
Copy `borg_exporter.rc` to `/etc/` and configure it (see the configuration section below).
|
||||
Copy `borg.env` to `/etc/borg` and replace your repokey and repository in it.
|
||||
|
||||
Copy the systemd unit and timer to `/etc/systemd/system`:
|
||||
```
|
||||
sudo cp prometheus-borg-exporter.* /etc/systemd/system
|
||||
```
|
||||
and run
|
||||
Copy the systemd unit to `/etc/systemd/system` and run
|
||||
|
||||
```
|
||||
sudo systemctl enable prometheus-borg-exporter.timer
|
||||
sudo systemctl start prometheus-borg-exporter.timer
|
||||
systemctl enable prometheus-borg-exporter.timer
|
||||
systemctl start prometheus-borg-exporter.timer
|
||||
```
|
||||
|
||||
Alternative: Use `ExecStartPost` in your borg backup timer itself to write our the metrics.

Alternative: Use `ExecStartPost` in your borg backupt timer itself to write our the metrics.
|
||||
|
||||
### Config file
|
||||
The config file has a few options:
|
||||
```
|
||||
BORG_PASSPHRASE="mysecret"
|
||||
REPOSITORY="/path/to/repository"
|
||||
PUSHGATEWAY_URL=http://pushgateway.clems4ever.com
|
||||
BASEREPODIR="/backup"
|
||||
NODE_EXPORTER_DIR="/path/to/node/exporter/textfile/collector/dir"
|
||||
```
|
||||
|
||||
* If you leave `BORG_PASSPHRASE=""` empty, no password will be used to access your backups
|
||||
* `REPOSITORY` should either point to a valid repository (if you're running this on each server you are backing-up) or should be left empty in case you set `BASEREPODIR`
|
||||
* `PUSHGATEWAY_URL` should be a valid URL for push gateway. If you're not using it, leave it blank (`PUSHGATEWAY_URL=""`) and data will be exported via node_exporter textfile collector
|
||||
* `BASEREPODIR` should point to a directory on disk from where you want to search for all the repos. This makes sense when you run this exporter on the backup server, so you can access all the backups in one place. It's only taken into consideration when `REPOSITORY=""`
|
||||
* `NODE_EXPORTER_DIR` should point to your node_exporter textfile collector directory (where it writes .prom files). It's used only if `PUSHGATEWAY_URL=""`
|
||||
|
||||
|
||||
### Caveats
|
||||
* The repository names shouldn't contain spaces
|
||||
* The archive names shouldn't contain spaces
|
||||
* The hostnames from the machines that do the export shouldn't contain spaces
|
||||
|
||||
### Troubleshooting
|
||||
You can manually run the script with `bash -x` to get the output of intermediary commands
