Metrics with Grafana and Prometheus

In this tutorial, you will learn how to set up Grafana to display Quickwit metrics using Prometheus. Grafana will visualize the metrics collected from Quickwit, allowing you to monitor its performance effectively.

Step 1: Create a Docker Compose File​

First, create a docker-compose.yml file in your project directory. This file will configure and run Quickwit, Prometheus, and Grafana as Docker services.

Here’s the complete Docker Compose configuration:

services:
  quickwit:
    image: quickwit/quickwit:0.9.0
    ports:
      - 7280:7280
    command: ["run"]

  grafana:
    image: grafana/grafana-oss:13.0.2
    container_name: grafana
    ports:
      - "${MAP_HOST_GRAFANA:-127.0.0.1}:3000:3000"

  prometheus:
    image: prom/prometheus:v3.13.1
    container_name: prometheus
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml  # Ensure prometheus.yml exists in the same directory
    ports:
      - 9090:9090

Explanation of Services​

  • Quickwit: Runs the Quickwit service on port 7280.
  • Grafana: Queries and displays data from Prometheus.
  • Prometheus: Collects metrics from Quickwit using the /metrics endpoint.

Step 2: Configure Prometheus​

Prometheus needs a configuration file to define how it scrapes metrics from Quickwit. Create a file named prometheus.yml in the same directory as your Docker Compose file with the following content:

global:
  scrape_interval: 1s
  scrape_timeout: 1s

scrape_configs:
  - job_name: quickwit
    metrics_path: /metrics
    static_configs:
      - targets:
          - quickwit:7280

Step 3: Start the Services​

Run the following command in your terminal to start all services defined in the Docker Compose file:

docker compose up

This will launch Quickwit, Prometheus, and Grafana services.

Step 4: Configure Grafana to Use Prometheus​

  1. Open Grafana in your browser at http://localhost:3000 and sign in with the default credentials (admin / admin). Grafana will ask you to choose a new password.
  2. Navigate to Connections > Data sources.
  3. Click Add new data source, select Prometheus, and set the URL to http://prometheus:9090.
  4. Click Save & test to verify the connection.

Step 5: Create or Use Pre-Configured Dashboards​

Now that Grafana is set up with Prometheus as a data source, you can create custom dashboards or use Quickwit's pre-configured dashboards:

  1. Go to the Dashboards section in Grafana.
  2. Import or create a new dashboard to visualize metrics.
  3. Alternatively, use one of Quickwit’s pre-configured dashboards.
