You can search for Kubernetes entities details in vRealize Network Insight.

Common Queries

  • Search Flows : flows where Kubernetes Object = Object name

    Example: flows where Kubernetes Cluster = 'Production'

  • View the service scale: kubernetes pods group by Kubernetes Services

  • View the node load: kubernetes Pods group by Kubernetes Node
  • View the node health: MemoryPressure and PIDPressure and DiskPressure and Ready of Kubernetes Node
  • View flow compliance: flows from Kubernetes Object name of the object to Kubernetes Object name of the object

    Example: flows from Kubernetes Namespace'PCI' to Kubernetes Namespace'Non-PCI'

  • View the Path topology:

    • Kubernetes service service name to Kubernetes service service name
    • Kubernetes service service name to Kubernetes pod pod name
    • Kubernetes pod pod name to Kubernetes pod pod name
