How? By using - CPU Flame graph.
What is "CPU Flame graph"?
A CPU flame graph is a tool used to analyze CPU usage in a program. It helps pinpoint performance bottlenecks by showing you how time is spent within different functions of your code.
Basically, it shows 2 metrics:
- Time on CPU: How long a function executes.
- Stack Depth: Depth of the function call within stack.
How can this optimize Kubernetes Pod performance?
There is a popular Kubernetes plugin called "kubectl-flame" that simplifies CPU profiling. It will deploy a helper container inside the original pod. It uses eBPF (extended Berkeley Packet Filter) for efficient profiling without modifying the application.
From there, you can potentially optimize your application code for better performance. That's it for today then.

1 年Do you know any other kubernetes plugins that can help to optimize performance? Do share.
