Grafana Prometheus Node-Exporter cAdvisor Loki - Docker Monitoring Stack

Get your monitoring stack up and running with one command using a Docker Compose stack featuring:

• Grafana : Dashboarding.
• Prometheus : Timeseries database for metrics.
• Node-Exporter : Node metrics.
• cAdvisor : Container metrics.
• Alertmanager : Alerting system.
• Uncomplicated Alert Receiver : UI with Received Alerts.
• Loki : Logs (including explore-logs).

Note: Due to docker-compose and the compose plugin, you might have one of the two installed. I have a Makefile that will detect which on you have installed.

You can list the targets using make.

Boot the stack with docker compose (or make up):

docker-compose up -d

Ensure all containers are running:

docker-compose ps

The output should looke like this:

 Name Command State Ports 
-----------------------------------------------------------------------------------------------------
cadvisor /usr/bin/cadvisor -logtostderr Up (healthy) 8080/tcp 
grafana /run.sh Up 0.0.0.0:3000->3000/tcp

promtail /usr/bin/promtail ... Up
uncomplicated-alert-receiver /app/uar Up 0.0.0.0:9094->8080/tcp

Access grafana on Grafana Home (or make open) and you should see the three dashboards that was provisioned:

Once you select the Node Metrics dashboard, it should look something like this:

When you select "Alerting" and "Alert rules" you will find the recording and alerting rules:

We can expand the alerting rules:

And then we can view more detail on a alert rule:

When we see one of our alerts are in an alert state:

We will see them be displayed in Uncomplicated Alert Receiver:

And for our container metrics we can access the Container Metrics dashboard:

Then for our last dashboard, the Container Log Search, by default the metric panel will be collapsed, but to expand it for visibility it will look like this:

And we can also view our Container Logs in the explore section:

For discovering the Logs we can navigate to the Explore / Logs view:

The following endpoints are available:

To remove the containers using docker compose (or make clean):

docker-compose down
