Graceful cancellation period on function timeout about azure-functions-dotnet-worker HOT 4 CLOSED

If the issue is with AppInsights ingestion then I think we can track these issues in your other GH issue and close this one?

Hi @dmytro-gokun, a cancellation token should be getting signaled on function timeout, I believe there a graceful shutdown period of a couple seconds but is not configurable.

Can you share more details about the issue you're seeing? If you're able to share a region, timestamp and invocation ID I should be able to investigate further. Thanks!

@liliankasem I did some testing and I think you are right about CancellationToken and 2 second timeout. The reason i thought cancellation token was not signaled is that i have code like this:

    public class Function
    {
        [Function("Function")]
        public async Task Run(
            [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post")] 
            HttpRequestData request,
            CancellationToken cancellationToken)
        {
            try
            {
                await DoWork(cancellationToken);
            }
            catch (OperationCanceledException)
            {
                Log.LogInformation("Canceled");
            }
        }
    }

with logs being set to Application Insights. So, that "Canceled" log does not end up in AI. I think the reason for that is that the worker gets restarted after the function timeout and some AI logs are lost. Not 100% sure about this though...
