Promfana is how I'm experimenting with Prometheus and Grafana. I'm using pushgateway to get metrics into Prometheus, because it's easier to do than have prometheus scrape, but I could easily configure prometheus and have it start scraping things if I wanted.
You will need Docker and docker-compose.
Setup persistent storage. I put this at /data, and the mount points in docker-compose expect these to be there:
mkdir -p /data/grafana /data/prometheus
To configure Prometheus, modify prometheus.yml. Similarly, to configure
grafana edit grafana.ini.
Then run make to build docker images.
You can make run to run things, or you can add a service to your machine that
starts docker-compose on boot. Example Systemd and Upstart units are included.
The first time you use Grafana you will have to configure the Prometheus back-end. I tried to make it so that you didn't have to, but I couldn't find documentation on that. If you know how to do that, please let me know.
You can see how to setup a Prometheus backend here.
