Kubernetes agent
Zenoss Cloud uses the data collected by the Zenoss agent for Kubernetes to create separate entities for each unique node, pod, container, and namespace in a cluster, and one entity for the cluster itself. To find a cluster in a dashboard scope query or Smart View query, enter the cluster name that you specified when you deployed the agent.
Entity relationships
The model data that the Zenoss agent for Kubernetes sends to Zenoss Cloud includes entity relationships. The following diagram illustrates the relationships:
The arrows show which objects affect other objects. The relationships are used to populate the related entities area in Smart View.
The following list replicates the diagram in text:
- Nodes affect pods and the cluster.
- The cluster affects namespaces.
- Namespaces and containers affect pods.
Metric data
All the metrics that the Zenoss agent for Kubernetes sends to Zenoss Cloud are gauges.
| Metric | Units |
|---|---|
| k8s.cluster.nodes.total | integer |
| k8s.cluster.pods.total | integer |
| k8s.cluster.containers.total | integer |
| k8s.cluster.cpu.ms† | millisecond |
| k8s.cluster.memory.bytes† | byte |
† The value is the sum of the same metrics for all containers in the cluster.
