The Kubernetes widgets 'performance indicator', 'overall performance', and 'network performance' does not load any data in Aria Operations

Products

• VMware Aria Suite

Issue/Introduction

• Kubernetes integration is functional in Aria Operations, and data collection is active
  
  
  
  
  
• Although other Kubernetes widgets displayed data, these 3 specific widgets 'key performance indicator, overall performance, and network performance' are empty
  
  

Environment

VMware Aria Operations 8.x
Kubernetes management pack 2.1.x

Cause

Prometheus is required for these widgets with Kubernetes management pack 2.1.x and 'Kubelet' must be selected from collector service options.

Resolution

• To use these widgets in the Kubernetes management pack 2.1.x, you must have a correctly set up Prometheus instance and choose 'Kubelet' from the collector service options. Prometheus is an open-source systems monitoring and alerting toolkit. For more information about Prometheus, see the Prometheus Overview .
  
  Note: The 'Kubelet' option is not available in Kubernetes management pack versions prior to 2.2 when Prometheus is not setup.
  
  1. Edit the Kubernetes adapter from integrations.
  2. Select 'Kubelet' from Collector Service drop-down and save the settings.
  
  
  
  
  
• To enable these widgets without Prometheus, update the Kubernetes management pack to version 2.2.0 or higher, and then choose 'Kubelet' from the collector service options.
