Prometheus Docker daemon metrics exporter
### Docker Engine
Create or edit /etc/systemd/system/docker.service.d/docker.conf,
enable the experimental feature and set the metrics address to 0.0.0.0:
```
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H fd:// \
--storage-driver=overlay2 \
--dns 8.8.4.4 --dns 8.8.8.8 \
--log-driver json-file \
--log-opt max-size=50m --log-opt max-file=10 \
--experimental=true \
--metrics-addr 0.0.0.0:9323
```
Check if the docker_gwbridge ip address is `172.18.0.1`:
```bash
docker run --rm --net host alpine ip -o addr show docker_gwbridge
```
### Docker Swarm
Create an overlay network:
```sh
docker network create \
--driver overlay \
netmon
```
Create dockerd-exporter global service (replace 172.18.0.1 with your docker_gwbridge address):
```sh
docker service create -d \
--mode global \
--name dockerd-exporter \
--network netmon \
-e IN="172.18.0.1:9323" \
-e OUT="9323" \
stefanprodan/dockerd-exporter:latest
```
Configure Prometheus to scrape the dockerd-exporter instances:
```
scrape_configs:
- job_name: 'dockerd-exporter'
dns_sd_configs:
- names:
- 'tasks.dockerd-exporter'
type: 'A'
port: 9323
```
Run Prometheus on the same overlay network as dockerd-exporter.
