- Container platform metrics
- Host infrastructure metrics
Docker EE 2.1 does not collect or expose application level metrics. The following are metrics Docker EE 2.1 collects, aggregates, and exposes:
- **Service state metrics**: These are metrics about the state of services running on the container platform. These types of metrics have very low cardinality, meaning the values are typically from a small fixed set of possibilities, commonly binary.
- Application health
- Convergence of K8s deployments and Swarm services
- Cluster load by number of services or containers or pods
- **Host infrastructure metrics**: These are metrics taken from te software & hardware infrastructure.
- CPU - Container-level CPU utilization, Node-level load average
- Memory - RSS, swap
- Network I/O - bandwidth, packets, drops
- Storage I/O - disk I/O, IOPs, capacity
- Operating System – file descriptors, open network connections, number of processes/threads
- **Container infrastructure system metrics**: These are application-level metrics derived from the container platform itself.
- Infrastructure Quorum Leader - Swarm RAFT, etcd, rethink
- UCP Component health - Healthy / Unhealthy
