300 responses could indicate page caching on the client browsers. Alternatively 300 responses could also indicate redirection of requests. A sudden change in this value could indicate a problem condition. |
| 400_errors |
The number of HTTP requests with response code between 400-499 |
Number
|
A high value indicates a number of missing/errored pages. |
| 500_errors |
The number of HTTP requests with response code between 500-599 in the last measurement period |
Number
|
Since responses with a status code of 500-600 indicate server side processing errors, a high value reflects an error condition. |

The number of HTTP requests with the response code 404 in the last measurement period |
Number
|
The 404 or Not Found error message is an HTTP standard response code indicating that the client was able to communicate with the server but either the server could not find what was requested, or it was configured not to fulfill the request and not reveal the reason why. A 404 error is often returned when pages have been moved or deleted. |
