docker stats in Swarm mode?

Im trying to setup docker in swarm mode and monitor the resource utilization of all the services/containers running in the swarm.

Docker stats on the manager node doesnt seem to show the resource utilization on the worker nodes.

Is there any way I can do this?

Thanks.

Solution

  • There's no direct way to retrieve all container stats of a given service in a Swarm. You'll probably have to use more steps to discover all tasks of a service, all node addresses, and each container id. The engine api docs should help you getting started. If you need some inspiration, I'd suggest you to peek into such overview dashboards like the https://github.com/charypar/swarm-dashboard or the https://github.com/dockersamples/docker-swarm-visualizer.
