You can monitor 28 different performance statistics in WebSphere Process Server.
Three performance statistics are available from earlier versions WebSphere® Process Server, which you can use to monitor performance for certain process server events. Additionally, you can now monitor 25 additional performance statistics in WebSphere Process Server version 6.0.2. These new statistics differ from the process server statistics in that they measure the performance of Service Component Architecture (SCA) processes. The SCA is the layer where your applications are actually processed, which differs from the process server events that are handled by the Common Event Infrastructure. The SCA-specific statistics are calculated from service invocations of an application, which may be comprised of one or more service components. You can use the SCA-specific statistics to assess a variety of performance measurements of the processing of your applications.
All performance measurements are either counters (a cumulative number of the firings of a given event point), or timers (the duration, measured in milliseconds, between the firings of two event points).
Statistic name | Type | Description |
---|---|---|
BadRequests | Counter | Number of failed invocations of the event. |
GoodRequests | Counter | Number of successful invocations of the event. |
ResponseTime | Timer | Elapsed time for event completion. |
Statistic name | Type | Description |
---|---|---|
GoodRequests | Counter | Number of server invocations not raising exceptions. |
BadRequests | Counter | Number of server invocations raising exceptions. |
ResponseTime | Timer | Duration measured on the server side between the reception of a request and computing the result. |
TotalResponseTime | Timer | Duration measured on the caller side, from the time a caller requests a service to the time when the result is available for the caller. Does not include the processing of the result by the caller. |
RequestDeliveryTime | Timer | Duration measured on the caller side, from the time a caller requests a service to the time when the request is handed over to the implementation on the server side. In a distributed environment the quality of this measurement depends on the quality of synchronization of system clocks. |
ResponseDeliveryTime | Timer | The time required to make the result available to the client. In the case of deferred response this time doesn’t include the result retrieve time. In a distributed environment the quality of this measurement depends on the quality of synchronization of system clocks. |
Statistic name | Type | Description |
---|---|---|
GoodRefRequests | Counter | Number of caller invocations to the SCA layer that do not raise exceptions. |
BadRefRequests | Counter | Number of caller invocations to the SCA layer that do raise exceptions. |
RefResponseTime | Timer | Duration measured on the caller side, from the time the caller makes a request to the SCA layer and the time when the results of that call are returned to the caller. |
BadRetrieveResult | Counter | Number of caller invocations to a datasource that do raise exceptions. |
GoodRetrieveResult | Counter | Number of caller invocations to a datasource that do not raise exceptions. |
RetrieveResultResponseTime | Timer | Duration measured on the caller side, from the time the caller makes a request to the datasource and the time when the datasource response is returned to the caller. |
RetrieveResultWaitTime | Timer |

GoodTargetSubmit | Counter | Number of SCA invocations to the service that do not raise exceptions. |
BadTargetSubmit | Counter | Number of SCA invocations to the service that do raise exceptions. |
TargetSubmitTime | Timer | Duration measured on the server side, from the time the SCA makes a request to the service and the time when the results of that call are returned to the SCA. |
GoodResultSubmit | Counter | Number of service invocations to the datasource that do not raise exceptions. |
BadResultSubmit | Counter | Number of service invocations to the datasource that do raise exceptions. |
ResultSubmitTime | Timer | Duration measured on the server side, from the time the service makes a request to the datasource and the time when the results of are returned to the service. |
Statistic name | Type | Description |
---|---|---|
GoodCB | Counter | Number of SCA invocations to the callback that do not raise exceptions. |
BadCB | Counter | Number of SCA invocations to the callback that do raise exceptions. |
CBTime | Timer | Duration from the time the SCA makes a request to the callback, and the time when the results from the callback are returned to the SCA. |
GoodCBSubmit | Counter | Number of invocations from the service to the SCA handling the callback that do not raise exceptions. |
BadCBSubmit | Counter | Number of invocations from the service to the SCA handling the callback that do raise exceptions. |
CBSubmitTime | Timer | Duration from the time the service makes a request to the SCA handling the callback, and the time when the results from the SCA to the service. |
