In your Site24x7 web client (Server > Kubernetes > Pods > select the Pod monitor > click Performance), you might get No Data for metrics such as CPU Limit and Requests, Memory Limit and Requests, CPU Utilization, and Memory Utilization (%) as shown below:
How do we calculate CPU Utilization and Memory Utilization?
CPU Utilization is calculated as below:
CPU Utilization = (CPU Usage/CPU Limit) * 100
Memory Utilization is calculated as below:
Memory Utilization (%) = (Memory Usage/Memory Limit) * 100
Since the CPU and Memory Utilization metrics depend on their respective configuration data limit, they will be shown as No Data.
