Duplicati prometheus exporter

This is an simple exporter made for Duplicati backup.

How it works

On your Duplicati backup interface or cli, you can configure in advanced options parameters for "send-http", with this configuration, Duplicati will send an post request to this exporter; so then exporter will gather metrics receved and expose a /metrics for prometheus.

# Cli configuration example
--send-http-url=http://<duplicati-exporter-instance>:5000/
--send-http-result-output-format=Json
--send-http-any-operation=true

Setup demo

For this demo is needed to be installed docker in your machine. How demo is setting up duplicati prometheus exporter app, prometheus and grafana, besides that, there is a configuration container that configure grafana datasource and dashboard, after that, this container send an example post to duplicati example exporter, you can see the configuration on docker compose file.

• In repository root, run:

docker compose up --force-recreate --build --always-recreate-deps

• After ~15 seconds the address http://localhost:3000 should be ready. Go to Grafana in your localhost

http://localhost:3000/d/ddmio2e27ctmod/duplicati-backup-dashboard

~This dashboard can change while i'm developing and improving.

Prometheus scrap config example

global:
  scrape_interval: 60s
  evaluation_interval: 30s
scrape_configs:
- job_name: duplicati_backup
  honor_labels: true
  static_configs:
  - targets: ['duplicati-prometheus-exporter:5000'] # you can change to set your exporter instance

Run duplicati prometheus exporter using docker

Docker is the better way to execute this application. If you prefer, you can build your own container image based on my Dockerfile to change anythong you want and store your container artifact where you need; but you also can use my docker image that is on my dockerhub

• Running docker image

docker run -p 5000:5000 aleixolucas/duplicati-prometheus-exporter

• After container run successfully you can access http://127.0.0.1/metrics (Change localhost ip if necessary).

Running with python

For this you have to install python3.9 or higher. You can change service port by setting a environment variable DUPLICATI_EXPORTER_PORT=PORT, default is 5000.

• In repository root, create an python venv

python -m venv .venv

• Then activate this venv

source .venv/bin/activate # Linux

C:\ .venv\Scripts\activate.bat # Window

• Install python packages required

pip install -r requirements.txt

• Finally

python duplicat-prometheus-exporter

DEBUG

Debug can be done by using LOG_LEVEL environment variable, supported values: DEBUG, INFO, WARNING, ERROR, CRITICAL.
