Python Azure Functions alert if timeout greater than 10 minutes

I have an Azure Functions app that is running on a timer trigger that I don't expect to exceed the 10 minute timeout limit, but I would like to receive an alert in the unlikely event that the application runs longer than 10 minutes. Is this possible to do in Application Insights? I didn't see an alert trigger for this use case. In Application Insights there is a "Long dependency duration" in the Smart Detection settings where I can add an email and there's also a "Failure Anomalies" alert rule already set up. Will either of these alert me if a function is running longer than 10 minutes?

I'd also like an alert if an individual function instance encounters any type of exception. I can set this up myself in the Python code by wrapping my code in a try except block and emailing if an exception is caught, but it would be easier if this was possible in Application Insights.

You can go to your host.json of your function app,

and change it like this:

{
  "version": "2.0",
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[1.*, 2.0.0)"
  },
  "functionTimeout": "00:10:00"
}

Then, if your instance is running more than 10 minutes, it will throw out an error.

So you can go to the Application Insight of your function and and select like below:

You can set the action type as Email/EMS and give it your email address, then you will receive an email when the timetrigger is timeout.
