# Dockerd exporter



Prometheus exporter for Docker daemon metrics. Inspired by https://github.com/stefanprodan/swarmprom

Prometheus exporter for Docker daemon metrics. Inspired by <https://github.com/stefanprodan/swarmprom>



## Requirements



You must enable Docker `metrics-addr` in all Swarm nodes.



When you are using a Docker version prior to v20.10.0, `experimental` flags must be enabled too.

Edit `/etc/docker/daemon.json` to add `"metrics-addr": "0.0.0.0:9323"` property:



Edit `/etc/docker/daemon.json` to add these properties:



```json

{

	...

	"experimental": true, #don't set this when Docker version >= 20.10.0

	"metrics-addr": "0.0.0.0:9323"

}

```

> Note: if your nodes are using Docker with version `< v20.10`, you must add `experimental: true` property too.



Don't forget to restart Docker daemon with `systemctl restart docker` (do it for every Swarm node).
