monitoring tool for open source applications, but when it comes to monitoring containerized workloads, Prometheus play very well, because it's backed up by open source community.</p> <p><strong>Challenge</strong>, when it comes to enterprises, especially using it inside Azure Kubernetes service, 🙋‍♂️🤔 question often asked is how to manage each Prometheus without getting escalation email from security team ⚠️☠️.</p> <p><strong>Solution</strong>, Implement Prometheus as a feature inside Azure monitor, and add extensions like Azure Monitor container insights and Azure Managed Grafana into it, hope other teams in Azure will create extensions for their services too.</p> <blockquote> <p>Prometheus is not free service, <a
