InfluxDB, Grafana, Cronitor

This is the docker-compose stack I use for my home network's monitoring. It contains the following containers:

• NGINX SSL termination for InfluxDB and Grafana traffic outside of Docker containers.
• InfluxDB to store all of the metrics (the central piece of the setup).
• Grafana to show pretty graphs and email me alerts.
• Cronitor for external monitoring of my Docker host and home network.
• NMC to include my UPS load, remaining runtime, and bedroom/living room temperatures in my Grafana graphs.

I also use the following services:

• SparkPost free tier for sending alerts emails.

Documentation

Visit the documentation for instructions on how to use this repository for your own metrics/graphing setup at home. I've documented everything I need to get up and running on my server in case I ever need to replace it from scratch.

Quick Start

Clone this repo locally (or fork it and clone that repo) to your Docker host (I put mine in /opt/influxdb). Also prepare your secrets by creating empty files with the right permissions:

sudo mkdir /opt/influxdb; cd $_
sudo git clone https://github.com/Robpol86/influxdb.git .
sudo mkdir -m0750 .secrets
for f in cronitor grafana.ini nmc; do
    sudo touch .secrets/$f; sudo chmod 0600 $_
done

Next you'll want to glance over the various configuration files in this repo. They work for me but you may have a different setup. Start with docker-compose.yml and look at other configuration files in this repository.

Once everything in docker-compose.yml looks good go ahead and start the containers:

cd /opt/influxdb; sudo docker-compose up -d
sudo firewall-cmd --permanent --add-port=8086/tcp
sudo firewall-cmd --permanent --add-port=3000/tcp
sudo systemctl restart firewalld.service

Verify everything works by running sudo docker ps. You should see "influxdb" and "grafana" in the NAMES column.
