Docker monitoring with Prometheus and cAdvisor with node and service selection

This is a dashboard for monitoring Docker container metrics collected by cAdvisor and stored in Prometheus TSDB.

Inspired by 193 and 8321

Features:

Depend on only cAdvisor metrics.
Select Jobs, Nodes and Services. Multi-value and Select-all are supported.
Use the new Time series panel. Faster
Merge network transmit and receive into one longer panel.
Merge Disk read and write into one longer panel.

This dashboard use the following metrics and their corresponding cadvisor model:

container_cpu_user_seconds_total : cpu
container_memory_usage_bytes : memory
container_network_receive_bytes_total : network
container_network_transmit_bytes_total : network
container_fs_reads_bytes_total : diskIO
container_fs_writes_bytes_total : diskIO

This dashboard expects the following labels on the metrics:

job
service
node
container

You may assign container_label_com_docker_swarm_service_name to service, and name to container using Prometheus’ metric_relabel_configs. Here is an example of the scrape rules.

metric_relabel_configs:
      - source_labels: ['container_label_com_docker_swarm_service_name']
        target_label: 'service'
      - source_labels: ['name']
        target_label: 'container'

You can add container_label_com_docker_swarm_service_name to the container by setting allowlisted_container_labels: ['com.docker.swarm.service.name'] for the cadvisor.
