Grafana Cloud's Kubernetes Monitoring app now provisions alerts using Grafana-managed alerting instead of data source-managed alerts, which can cause notification routing issues after reinstallations because the two systems use separate contact points, policies, and Alertmanagers. Users should upgrade via the app's Update button, reconfigure notifications in Grafana's built-in alerting system after reinstalls, and migrate custom alert rules out of the integrations-kubernetes namespace to avoid losing them during upgrades.
