Docker Engine Monitoring

What Is Docker Engine?

Docker Engine is the core component of the Docker platform, responsible for managing containers on your infrastructure. It provides a scalable and efficient framework for running and managing containers, thereby making application deployment more simplified and consistent across environments. For more information, visit the official Docker Engine documentation.

Understanding Docker Engine Performance Metrics

Container Actions

  • docker_engine.engine_daemon_container_actions: Tracks the actions performed on containers, such as create, delete, and start.

Containers In Various States

  • docker_engine.engine_daemon_container_states_containers: Shows the number of containers in ‘running’, ‘paused’, and ‘stopped’ states.

Builder Builds Fails By Reason

  • docker_engine.builder_builds_failed_total: Captures the reasons for failed builds, aiding in pinpointing errors in build processes.

Health Checks

  • docker_engine.engine_daemon_health_checks_failed_total: Monitors the failure rate of health checks, which are vital for maintaining container health.

Swarm Manager Metrics

  • docker_engine.swarm_manager_leader: Determines if the node is the current swarm manager leader.
  • docker_engine.swarm_manager_object_store: Keeps track of objects in the swarm manager, like nodes, services, and tasks.
  • docker_engine.swarm_manager_nodes_per_state: Represents nodes in different states such as ‘ready’ and ‘disconnected’.
  • docker_engine.swarm_manager_tasks_per_state: Provides insights into task states within the swarm, like ‘running’ and ‘shutdown’.
