Kubernetes Alerts

Sumo Logic monitors provide you with out-of-box alerts that help determine if your Kubernetes cluster is available and performing well. The alerts, listed on this page, are installed by default when you set up data collection using Helm or YAML. They are built based on metrics datasets and have preset thresholds.
