In this series, we are going to talk about Linux performance measurement, how to measure it right.
Other parts in this series include: Now when we speak about understanding the performance as related to those components, that does NOT mean that your CPU is a problem and you just need to go ahead and get more CPU.
But maybe that is not what you want to do, and you want to understand what’s actually causing the usage, and how you want to resolve it.
There are a number of ways you can use and consume that information, for example, there is a Cloudflare Exporter, where you can get that information to Prometheus for monitoring.
But it is important to understand for capacity planning, because if you know your application scales linearly with the workload, and you can see that your CPU usage is only five percent, you could probably guess you can get at least 20x the growth on your application.
