Published date: March 17, 2023
On 14 March 2026, we will retire Container insights recommended alerts (custom metrics) (preview). Before that date, you’ll need to migrate to Prometheus recommended alert rules (preview).
Prometheus recommended alert rules (preview) provides all the functionality of Container insights recommended alerts (custom metrics) (preview) plus new features, including:
- Cost efficiency – Prometheus metrics are more cost efficient than custom metrics.
Prometheus metrics are cloud-native and open-source.
To avoid or minimize disruption to your monitoring workflows setup using the custom metric alert (preview) feature, please refer to migration guidance and take the recommended actions before 14 March 2026. You will not be able to onboard additional monitored Kubernetes clusters to this feature using Azure Portal.
