Web-Specific Measures

Describes the measures that are specific for the Web.
Measure Description
HTTP request retries The number of times a client is forced to retry a request. This may happen when the server closes a persistent connection (available with Keep-Alive or HTTP/1.1) because of a timeout occurring while the client tries to send a request. This counter is used only by low-level web functions.
HTTP redirections The number of HTTP redirections performed due to a Web server response with status code 3xx. This measure is incremented only by Web functions.
HTTP re-authentications The number of re-authentications necessary because of a status code 401 or 407 returned by the Web server. This counter is used only by Web functions that perform basic authentication.
HTTP hits The number of HTTP requests that arrive at the Web server. This measure is incremented only by Web functions.
Hits failed The number of failed HTTP requests. This measure is incremented only by Web functions.
HTTP 1xx responses The number of HTTP responses containing status codes indicating that their content has the status informational. This measure is incremented by Web functions.
HTTP 2xx responses The number of HTTP responses containing status codes indicating successful requests. This measure is incremented by Web functions.
HTTP 3xx responses The number of HTTP responses containing status codes indicating redirected requests. This measure is incremented by Web functions.
HTTP 4xx responses The number of HTTP responses containing status codes indicating client errors. This measure is incremented by Web functions.
HTTP 5xx responses The number of HTTP responses containing status codes indicating server errors. This measure is incremented by Web functions.
HTTP cache conditional reloads The number of requests sent to the server to download an item if its content has changed since it was last placed in the cache.
HTTP cache hits The number of times requests that are fulfilled from the cache.
HTTP cookies sent The number of cookies sent by low-level web functions. If the header line of an HTTP cookie request contains multiple cookies, each cookie in the header is counted.
HTTP cookies received The number of cookies received by low-level web functions. If the HTTP response includes multiple cookie header lines, each cookie of these header lines is counted.
HTTP pages The number of HTML pages requested by the page-level Web API.
