Hi @Balasubramanian KN the "Alerts" feature is not available in function app with Linux OS under consumption plan.

However, you can still monitor your Function App for HTTP server errors using Azure Monitor.
Azure Monitor can collect metrics and logs from your Function App and provide insights into its performance and health. You can also set up alerts based on specific metrics or log search queries to notify you when issues occur.

• click on "Metrics" on overview page.
• In the "Metrics" blade, select "Function App" as the resource type and select the appropriate metric namespace and metric name for HTTP server errors.
• you see a create an alert rule on top to configure alerts.
  or
• Under the "Monitoring" section, click on "Logs".
• In the "Logs" blade, create an alert based on a query you write. for example, the following query to search for HTTP server errors:

requests
| where resultCode >= 500

This query searches for requests that have a result code of 500 or higher.
