How to interpret my Request Metrics?

General Information

For general information on monitoring, please refer to the dedicated article (How do I monitor my platforms performance?).

Getting Started

Request metrics provide meaningful information about HTTP(S) requests leading to your application.

Available Metrics

HTTP Response Codes

The number of HTTP response codes generated by all the web servers and aggregated by response code:

  • 2xx successful – the request was successfully received, understood, and accepted
  • 3xx redirection – further action needs to be taken in order to complete the request
  • 4xx client error – the request contains bad syntax or cannot be fulfilled
  • 5xx server error – the web server failed to fulfil an apparently valid request

Web Response Time (ms)

The total time elapsed, in seconds, from the time the load balancer sent the request to the web server until the web server started to send the response headers.

Web Requests Traffic

  • Success Requests
    The number of requests processed over IPv4 and IPv6 aggregated across all web servers. This count includes only the requests with a response generated by a target of the load balancer.
  • Failed Requests
    The number of connections that were not successfully established between the load balancer and the web servers. Because the load balancer retries the connection when there are errors, this count can exceed the request rate.
