K8s Operating System Metrics
For each application deployed in Rancher, two dashboards are implemented and provided to the application owners to facilitate monitoring and management. The first dashboard delivers detailed OS-level metrics for the workloads, offering insights into resource utilization such as CPU, memory, and disk usage at the operating system level. The second dashboard focuses on pods, presenting metrics such as resource limits, requests, and performance data. These dashboards empower application owners with the visibility needed to optimize performance and ensure operational stability.
