Nov 29, 2023 · Prometheus is a way to easily start open source monitoring for cloud native and Kubernetes instances, but it does require technical and developer resources to manage over time and has scalability limitations. Additionally, it can get complex for large scale enterprise environments that require data duplication or have spread-out infrastructure.
