Azure kubernetes - Prometheus 处理多个应用程序

Question

I am planning to deploy 15 different applications initially and would endup with 300+ applications on azure kubernetes and would be using Prometheus and Grafana for monitoring.

I have deployed both the Prometheus and Grafana on a separate namespace on the dedicated node.

How do I enable horizontal pod scaling for Prometheus and Grafana?

Answer 1

You can scale your applications based on custom metrics gathered by Prometheus and presented in the Grafana dashboard.

In order to do that you'll need the Prometheus Adapter to implement the custom metrics API, which enables the HorizontalPodAutoscaler controller to retrieve metrics using the custom.metrics.k8s.io API. You can define your own metrics through the adapter's configuration so the HPA would scale based on those stats.

Here you can find a short guide that would get you started.
