It is the users responsability to implement Firewall/IpTables and SSL. Security has not been implemented in this project. This project is intended to be a quick-start to get up and running with Docker and Prometheus. Click the green button Add Data Source.Įnsure the Datasource name Prometheusis using uppercase P.Click the Grafana Menu at the top left corner (looks like a fireball).Now we need to create the Prometheus Datasource in order to connect Grafana to Prometheus Let this run for a few minutes and you will notice the load alert appear. High load test alert - docker run -rm -it busybox sh -c "while true do : done" Also check the alerts in both the Alert Manager and Prometheus Alerts just to understand how they flow through the system. Stop the node_exporter container and you should notice shortly the alert arrive in Slack. View Prometheus alerts View Alert Manager Test AlertsĪ quick test for your alerts is to stop a service. Copy the Webhook URL into the alertmanager/config.yml URL section.Click on Add Incoming WebHooks integration.Click on the "incoming webhook integration" link. Choose Incoming Web Hooks link under Send Messages.The Slack configuration requires to build a custom integration. Slack configuration - alertmanager/config.yml Grafana Dashboard - dashboards/Grafana_Dashboard.jsonĪlerting has been added to the stack with Slack integration. If you have any changes you would like to see in the Dashboard let me know so I can update Grafana site as well. This dashboard is intended to help you get started with monitoring. Simply select Import from the Grafana menu -> Dashboards -> Import and provide the Dashboard ID #179 I created a Dashboard template which is available on Grafana Docker Dashboard. If you would like to automate the installation of additional dashboards just copy the Dashboard JSON file to /grafana/provisioning/dashboards and it will be provisioned next time you stop and start Grafana. These directories contain YAML files which allow us to specify which datasource or dashboards should be installed. The /grafana/provisioning/ directory contains the datasources and dashboards directories. This allows us to automate the process of adding Datasources & Dashboards. Grafana version 5.0.0 has introduced the concept of provisioning. From the /prometheus project directory run the following command: Once configurations are done let's start it up. If you wish to change names of the services you can add the "container_name" parameter in the docker-compose.yml file. The names defined in this file are actually sourced from the service name in the docker-compose file. The targets section is where you define what should be monitored by Prometheus. If you would like to change which targets should be monitored or make configuration changes edit the /prometheus/prometheus.yml file. Installation & ConfigurationĬlone the project locally to your Docker host. Docker Swarm is installed automatically when using Docker for Mac or Docker for Windows. Ensure you install the latest version of docker and docker swarm on your Docker host machine. This will allow you to quickly test the stack to see if it meets your needs.īefore we get started installing the Prometheus stack. The Try in PWD below allows you to quickly deploy the entire Prometheus stack with a click of the button. Here's a quick start using Play-With-Docker (PWD) to start-up a Prometheus stack containing Prometheus, Grafana and Node scraper to monitor your Docker infrastructure. Interesting Projects that use this RepoĪ Prometheus & Grafana docker-compose stack.I read the documentation but cannot find a way to investigate further. It works fine, with other source_labels, but as soon as I use 'node_id' or 'node_name', 'instance' is not changed. I have configured the prometheus.yml like that:īut this does not work. My idea was to use the relabelling functionnality to replace the 'instance' label, or to add a new label to all metrics. This image exposes a metric 'node_meta" containing these labels, exemple: I use a fork of the node exporter (stefanprodan/swarmprom-node-exporter) which gets the node hostname by sharing the node host file: This value changes after each service restart. The way I configured it does not allow me to get the hostname in the instance label, but rather the ip of the node-exporter container. I am trying to monitor nodes of a swarm cluster. I am a newby with Prometheus, I am not very confortable so far.
