Please note that this is not an exhaustive list and there may be additional test scenarios.
The purpose of these tests is to verify the functionality and compatibility of features such as metric collection, real-time metric querying, log querying for various resources (Pods, Services, StatefulSets, Deployments, NPD), and log filtering. The tests have been conducted on Kubernetes versions 1.26, 1.23.0 to 1.23.13, 1.24.0 to 1.24.7, 1.25.0 to 1.25.3, 1.22, 1.21, 1.20, 1.19, and 1.18.
