Here’s a sample view of a request from the Task Queue service. The log includes the name of the queue (in this case default), the task’s name (the long number starting with 1636460), and the instance that handled the request (the blue text on the bottom).
An important note: a quick and easy way to figure out if a request comes from the Task Queue is to look at the request’s IP address. All Task Queue requests come from the IP 0.1.0.2.
