Used for my grafana instance (to get latency of my services)

Still in early development, but it's working for me.

I'm going to make it more generic and add more features.

Docker installation

First, you need to build the image. I'm going to make an automated build later.

git clone https://github.com/Farmeurimmo/GrafanaMonitoring.git && cd GrafanaMonitoring && sh build.sh

Then, you need to choose the method, for example if you don't have an influxdb instance with grafana, use the All-in-one method. If you already have an influxdb instance, use the Just the monitor method.

All-in-one

Here is my docker-compose.yml file for my monitoring stack. I'm using cloudflare tunnel to expose my services via the cloudflared network. Please change the INFLUXDB_TOKEN and GF_SECURITY_ADMIN_PASSWORD environment variables.

You will need to set up influxdb and create a bucket with an api token (for INFLUXDB_TOKEN env var).
