Thank you @Julien and @Stuart.
By default the Docker daemon is running on the socket, and can only
retrieve the metrics from the current Docker daemon.
On the other Docker Swarm manager node, setup the Daemon docker using
http/https and it should solve the problem.
[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H fd:// -H tcp://<ip_address_of_the_node>:2376
Make sure the port is available!
That was using the solution, defining a new job in the prometheus.yml
configuration file:
- job_name: 'test-nodes-clusterB'
dockerswarm_sd_configs:
- host: tcp://<ip_address>:2376
role: nodes
relabel_configs:
# Fetch metrics on port 9323.
- source_labels: [__meta_dockerswarm_node_address]
target_label: __address__
replacement: $1:9323
# Set hostname as instance label
- source_labels: [__meta_dockerswarm_node_hostname]
target_label: instance
