Hi @Anonymous
Thank you for asking this question on the **Microsoft Q&A Platform. **
First, add a log analytics workspace to your Function App
Then you must create an alert role with the signal "Custom log search"
If you have this message
is because you might not already configure the log analytics or still you don't have data on it.
Here you must create a query that gives the result that you require.
After creating the query, you can configure the parameter of your alert.
Hope this helps!
