Grafana recently added support for Prometheus. Let's take a look at how to get it up and running.

Grafana Prometheus Dashboard

First let's setup a quick Prometheus server to scrape itself so we have some metrics to play with:

tar -xzf prometheus-2.0.0.linux-amd64.tar.gz
cd prometheus-*
cat <<'EOF' > prometheus.yml
 scrape_interval: 10s
 evaluation_interval: 10s
 - job_name: 'prometheus'
    - targets:
      - localhost:9090
./prometheus &

Next let's get Grafana up and running:

tar -xzf grafana-latest.linux-x64.tar.gz
cd grafana-*
./bin/grafana-server &
