Incoming HTTP Requests
The Incoming HTTP Requests event shows time intervals where your web application processes incoming HTTP requests. This includes the time between a server receiving a request and it sending a response. Outgoing HTTP requests are not shown.
Select the Incoming HTTP Requests event to analyze how your web app processes requests. For example, to process a request, a web application may communicate with a number of external resources via their APIs, access databases, process data, and so on. Performance flaws in any of these steps may result in overall slow response of your application. In such a case, you can use the Incoming HTTP Requests filter to determine the exact cause and find the methods that run slowly.
After you select the Incoming HTTP Requests event, you can fine-tune the result with the Incoming HTTP Requests: URL and Incoming HTTP Requests: Method sub-filters.
Incoming HTTP Requests: URL
The Incoming HTTP Requests: URL sub-filter shows distribution of incoming HTTP request times between requests to specific URLs. Use this sub-filter to determine how long a request to a particular URL takes.
URL.
Total time spent on a request to the URL summed up for all selected threads.
The percentage of time spent on a request to the URL relative to the total selected time.
To apply the 'Incoming HTTP Requests: URL' filter
Select the desired URL in the filter.
After you select a URL, other filters will show data only for the time intervals where the requests to the selected URL were processed.
