Kubernetes and k8s apps monitoring for free

For those interested in Kubernetes monitoring and monitoring the applications in Kubernetes, Signoz is an open-source solution you can use for free.

There is also a cloud version to get a SaaS app without the maintenance and administration burden.

I tried Signoz on Azure Kubernetes (AKS). Installation takes minutes, and you have much better observability for your k8s cluster and applications.
