## What breaks

Azure Monitor deprecates the sidecar for remote-write of Prometheus metrics to Azure Monitor Workspace on 31 Mar 2027. Microsoft recommends that self-hosted Prometheus or Prometheus Operator setups remote-write directly to Azure Monitor Workspace instead of using the sidecar. Microsoft encourages a transition to direct Prometheus remote-write to ensure uninterrupted service.

## What to do

1. Configure self-hosted Prometheus or Prometheus Operator to remote-write directly to Azure Monitor Workspace.
2. Follow the configuration guidance in [the official documentation](https://learn.microsoft.com/azure/azure-monitor/metrics/prometheus-remote-write?tabs=system-managed-identity). All authentication methods are supported in the Prometheus remote-write configuration.
3. Direct remote-write removes the need for the sidecar.

## Replacement

Direct Prometheus remote-write to Azure Monitor Workspace
