Prometheus Swarm

A sample image that can be used as a base for collecting Swarm mode metrics in Prometheus

How to use it

You can use the provided docker-stack.yml file as an example. You can deploy the full stack with the command:

Create overlay network

Before deploying, you need to create an overlay network for monitoring with prometheus

docker network create --driver overlay --attachable monitoring

Set label on a specific host

Prometheus uses internal TSDB which needs a persistent volume I set the constraint on Prometheus service therefore you should set the service=prometheus label

docker node update --label-add service=prometheus infa-swarm-t1003

Deploy prometheus stack

docker stack deploy -c docker-compose-stack.yml prometheus

You might need to apply this IPTables rule to work docker-exporter service This rule will allow the container to reach the host on it's own exposed port which is 4999 moby/moby#24370

iptables -I INPUT 1 -i docker_gwbridge -j ACCEPT

Deploy Grafana Dashboard

docker stack deploy -c grafana.yml grafana

Now you can access your Grafana dashboard via this URL

• http://:3000

Add a data source

Import Dashboards

You can find some predefined dashboard JSON files in the grafana directory

Import them to create essential dashboards
