# A Docker Stack which Monitors your GitHub Repos
Here's a quick start to stand-up a Docker [Prometheus](http://prometheus.io/) stack containing Prometheus, Grafana and [github-exporter](https://github.com/infinityworksltd/github-exporter) to collect and graph GitHub statistics.
# A Docker Stack which Monitors your home network
Here's a quick start to stand-up a Docker [Prometheus](http://prometheus.io/) stack containing Prometheus, Grafana with [blackbox-exporter](https://github.com/prometheus/blackbox_exporter) and [speedtest-exporter](https://github.com/stefanwalther/speedtest-exporter) to collect and graph home network connections and speed.
## Pre-requisites
Before we get started installing the Prometheus stack. Ensure you install the latest version of docker and [docker-compose](https://docs.docker.com/compose/install/) on your Docker host machine. This has also been tested with Docker for Mac and it works well.

## Installation
Clone the project to your Docker host.
If you would like to change which targets should be monitored or make configuration changes edit the [/prometheus/prometheus.yml](https://github.com/vegasbrianc/prometheus/blob/version-2/prometheus/prometheus.yml) file. The targets section is where you define what should be monitored by Prometheus. The names defined in this file are actually sourced from the service name in the docker-compose file. If you wish to change names of the services you can add the "container_name" parameter in the `docker-compose.yml` file.

The targets section is where you define what should be monitored by Prometheus. The names defined in this file are actually sourced from the service name in the docker-compose file. If you wish to change names of the services you can add the "container_name" parameter in the `docker-compose.yml` file.
## Configuration
In order to pull GitHub stats consistently it is recommended you create a personal access token inside of GitHub. This token will allow you to query the GitHub API more frequently than a public user. [Create GitHub Token](https://github.com/settings/tokens). It is only necessary to give the repo scope to the token permission.
To change what hosts you ping you change the `targets` section under `blackbox` in [/prometheus/prometheus.yml](./prometheus/prometheus.yml) file.

Copy the GitHub Token you created and paste into the bottom of the [docker-compose.yml](https://github.com/vegasbrianc/github-monitoring/blob/master/docker-compose.yml) file under the metrics service section replacing the `GITHUB_TOKEN` with your newly created token.
The REPOS variable can also be updated to point to the Repos that you wish to monitor. In my example I monitor freeCodeCamp and Docker.
metrics:
tty: true
stdin_open: true
expose:
- 9171
image: infinityworks/github-exporter:latest
environment:
- REPOS=freeCodeCamp/freeCodeCamp, docker/docker
- GITHUB_TOKEN=<GitHub API Token see README>
networks:
- back-tier
For speedtest the only relevant configuration is how often you want the check to happen. It is at 5 minutes by default which might be too much if you have limit on downloads. This is changed by editing `scrape_interval` under `speedtest` in [/prometheus/prometheus.yml](./prometheus/prometheus.yml).
Once configurations are done let's start it up. From the /prometheus project directory run the following command:
$ docker-compose up -d
That's it. docker-compose builds the entire Grafana and Prometheus stack automagically.
The Grafana Dashboard is now accessible via: `http://<Host IP Address>:3000` for example http://192.168.10.1:3000

The DataSource and Dashboard for Grafana are automatically provisioned. You can still install the dashboard manually if you choose below.
