The Docker swarm cluster has many monitoring options, and the Cadvisor+influxdb+grafana solution is powerful and flexible. The most important thing is that this program is open source, free, easy to use, is an inexpensive version of the monitoring program. Reference Document: https://botleg.com/stories/monitoring-
