A Prometheus & Grafana demo
Here's a quick start using only docker and docker-compose to start-up a Prometheus demo on your local machine containing Prometheus, Grafana, cadvisor and node-exporter to monitor your Docker infrastructure and machine.
Installation & Configuration
Clone the project locally to your machine.
If you would like to change which targets should be monitored or make configuration changes edit the
The targets section is where you define what should be monitored by Prometheus. The names defined in this file are 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
This project contains sane defaults meaning that you can just go ahead and start it up by running the foloowing command:
$ docker-compose up -d
See what containers was started by running
$ docker ps
Grafana is now accessible via:
username - admin password - foobar (Password is stored in the `config.monitoring` env file)
Now we need to create the Prometheus Datasource in order to connect Grafana to Prometheus
- Click the
GrafanaMenu at the top left corner (looks like a fireball)
- Click the green button
Add Data Source.
Alerting has been added to the stack with Slack integration. 2 Alerts have been added and are managed:
Slack configuration -
The Slack configuration requires to build a custom integration.
- Open your slack team in your browser
- Click build in the upper right corner
- Choose Incoming Web Hooks link under Send Messages
- Click on the "incoming webhook integration" link
- Select which channel
- Click on Add Incoming WebHooks integration
- Copy the Webhook URL into the
- Fill in Slack username and channel
View Prometheus alerts
View Alert Manager
A quick test for your alerts is to stop a service. Stop the node_exporter container and you should notice shortly the alert arrive in Slack. Also check the alerts in both the Alert Manager and Prometheus Alerts just to understand how they flow through the system.
High load test alert -
docker run --rm -it busybox sh -c "while true; do :; done"
Let this run for a few minutes and you will notice the load alert appear. Then Ctrl+C to stop this container.
There are Dashboard templates included in this demo within the
dashboard folder, simply import them into grafana.
The dashboards are intended to help you get started with monitoring using Prometheus.
Docker Dashboard based on cadvisor data -
Alerting Dashboard -
Prometheus 2 Dashboard -
System monitoring Dashboard based on node exporter -
This project is intended to be a quick-start to get up and running with Docker and Prometheus. Security has not been implemented in this project. It is the users responsability to implement sensible security practices.
It appears some people have reported no data appearing in Grafana. If this is happening to you be sure to check the time range being queried within Grafana to ensure it is using Today's date with current time.
The node-exporter does not run the same as Mac and Linux. Node-Exporter is not designed to run on Mac and in fact cannot collect metrics from the Mac OS due to the differences between Mac and Linux OS's. I recommend you comment out the node-exporter section in the
docker-compose.yml file and instead just use the cAdvisor.
