Counter definitions


Web application counters

Web application counter definitions. This table displays properties for web application counters.

Name Key Description Granularity Type Level Overhead
LoadedServletCount webAppModule.numLoadedServlets The number of loaded servlets. Per web application CountStatistic All Low
ReloadCount webAppModule.numReloads The number of reloaded servlets. Per web application CountStatistic All Low


Servlet counters

Servlet counter definitions. This table displays properties for Servlet counters.

Name Key ID Description Granularity Type Level Overhead
RequestCount webAppModule.servlets.totalRequests 11 The total number of requests that a servlet processed. Per servlet CountStatistic Basic Low
ConcurrentRequests webAppModule.servlets.concurrentRequests 12 The number of requests that are concurrently processed. Per servlet RangeStatistic Extended High
ServiceTime webAppModule.servlets.responseTime 13 The response time, in milliseconds, of a servlet request. Per servlet TimeStatistic Basic Medium
ErrorCount webAppModule.servlets.numErrors 14 Total number of errors in a servlet or JavaServer Page (JSP). Per servlet CountStatistic Extended Low
ResponseTime webAppModule.servlets.asyncContextResponseTime 18 The response time (in milliseconds) for an AsyncContext associated with a servlet to complete. Per servlet TimeStatistic Extended Medium


URL counters

URL counter definitions. This table displays properties for URL counters.

Name Key ID Description Granularity Type Level Overhead
RequestCount webAppModule.url.totalRequests 15 The total number of requests processed for an URI associated with a servlet. Per URI CountStatistic Basic Low
ConcurrentRequests webAppModule.url.concurrentRequests 16 The number of requests processing concurrently for a URI associated with a servlet. Per URI RangeStatistic Extended High
ServiceTime webAppModule.url.responseTime 17 The average service response time, in milliseconds, for an URI associated with a servlet. Per URI TimeStatistic Basic Medium
ResponseTime webAppModule.url.asyncContextResponseTime 19 The response time (in milliseconds) for an AsyncContext associated with a URI to complete. Per URI TimeStatistic Medium All


Asynchronous request dispatcher counter

Asynchronous request dispatcher counter definitions. This table displays properties for Asynchronous request dispatcher counters.

Name Key ID Description Granularity Type Level Overhead
ServiceTime ard.averageResponseTime 1 The average response time, in milliseconds, in which an asynchronous request dispatcher (ARD) request is completed.

This metric also processes asynchronous servlet and JSP requests that are cached by the dynamic cache service.
