Upgrade Notices

Alloy Operator

Alloy v3 introduces the use of the Alloy Operator. Upgrades should be transparent for Big Bang users, and we don't expect any breaking changes. You can refer to the Alloy release notes for additional information here: https://github.com/grafana/k8s-monitoring-helm/tree/main/charts/k8s-monitoring#breaking-change-announcements

Service Monitors

Due to an inability to use post-renderers on resources managed by the new Alloy Operator, Service Monitors are now defined at the root level in chart/values.yaml and managed by the chart/templates/bigbang/servicemonitor.yaml template.
