Customize Tanzu Observability Dashboard for VMware Tanzu for Kubernetes Operations
Tanzu Observability provides various out-of-the-box dashboards. You can customize the dashboards for your specific deployment. This document provides the steps to customize the dashboards to monitor the following Tanzu for Kubernetes Operations (informally known as TKO) components:
- Tanzu Kubernetes Grid Clusters
- VMware vSphere
- NSX Advanced Load Balancer
We will customize the following dashboards:
- Summary Dashboard
- Resource Utilization Dashboard
- Health Check Dashboard
- Network Dashboard
Prerequisites
Ensure that Tanzu Observability is fetching data from the following: Tanzu Kubernetes Grid Clusters, NSX Advanced Load Balancer, and VMware vSphere.
Summary Dashboard for Tanzu for Kubernetes Operations on vSphere
The summary dashboard for Tanzu for Kubernetes Operations on vSphere displays the charts and analytics data for Tanzu Kubernetes Grid clusters,NSX Advanced Load Balancer, and vSphere.
This dashboard is combination of the following out-of-the-box dashboards: Kubernetes Summary Dashboard, Avi Summary Dashboard, and VMware vSphere Dashboard.
