The Cluster Agent Dashboard metrics are derived from the Kubernetes API, and they report information for the clusters and pods. The Cluster Agent reports events on these Kubernetes and hardware resources for any defined set of namespaces.

AppDynamics monitors cluster health and Kubernetes objects for:

Hardware Resources|Cluster|Pods With Missing Dependencies (Pod Metrics for Inventory Tab)
Pods with No Limits

Number of pods with no limits (on CPU/memory) set. If you specified limits on any pod that you are starting, this metric indicates how many pods do not have a limit defined (Displays in the Inventory tab, under Pod Metrics).

Inventory > Pods > No LimitsHardware Resources|Cluster|Pods With No Limits
Pods With No Liveness ProbeNumber of pods with no liveness probe. If you configured a probe in Kubernetes to monitor liveness, the values display in the Inventory tab, under Pod Metrics.Inventory > Pods > No Probes -LivenessHardware Resources|Cluster|Pods With No Liveness Probe
