Statistics
The Statistics administrative page shows performance-related data for your XperienCentral deployment. The real-time data is updated every ten seconds. Click [Dump] to export the statistics from the last 2 hours to a comma separated values (CSV) file which you can examine in more detail. For each statistical graph, you can click [Load History] to display the data for the last number of hours selected.

Deployment Overview
In the Overview section, the following information is shown for your XperienCentral deployment:
Item | Description |
|---|---|
XperienCentral Version | The version of XperienCentral that is currently running. |
Java Version | The version of Java that the deployment is currently running. |
System Version | The version of the operating system on which XperienCentral is currently running. |
Available CPUs | The number of CPUs that are currently available to the XperienCentral deployment. |
XperienCentral Uptime | The number of days, hours, and minutes that the current XperienCentral process has been running. |
Current Date | The current date and time (day, month, date, HH:MM:SS) expressed in the local time zone. |
Requests per Second
This chart shows the number of requests processed by the XperienCentral application each second (averaged over 10 seconds). Using the mouse wheel, you can zoom in and out of the data to see more or less detail, from a maximum of fifteen minute intervals to a minimum of 1 millisecond.

Cumulative Request Profile(s)
This statistic shows the sum of time that XperienCentral spent processing requests in a number of categories during the last 2 hours. This provides insight into the time spent in several XperienCentral components. Since real time is measured instead of system time, the total time spent may be higher than the actual time that has elapsed on systems with a high load . For each request arriving to XperienCentral, the time spent in several categories is logged. Time logging for each request is started at the broadest category, namely "Request handling". This includes all aspects of dealing with requests that are not part of a more specialized category. This includes, for example, sending data to the client, handling SSI includes and signing forms. More specific aspects of handling requests are logged in their own category: The categories are:
Category | Description |
|---|---|
REST API | Processing requests that access the XperienCentral REST API (typically from the user interface). |
Personalization | The processing of personalized requests, or parts thereof, involving an XSL transformation. |
Request Handling | The processing of regular requests. |
Media queries | The retrieving of content for dynamic content overviews. |
Regular rendering | The rendering of content that could not be retrieved from the cache. |
Cache access | The loading of data from the physical disk cache, the memory cache or the timestamp database. |
Friendly URL resolving | The resolving of friendly URLs. |
System Load
This statistic shows the load on the system as reported by the Operating System; This is not available when the system is running a Windows operating system.

Memory Usage
This statistic shows the amount of available memory and the amount of memory that is currently being used by the JVM in megabytes. Using the mouse wheel, you can zoom in and out of the data to see more or less detail, from a maximum of fifteen minute intervals to a minimum of 1 millisecond.

Request Profile
This statistic shows the sum of time that XperienCentral spent processing requests. Because this statistic measures real time instead of system time, the total time spent may be higher than the actual time that has elapsed. The following categories are measured:
Category | Description |
|---|---|
REST API | Processing requests that access the XperienCentral REST API (typically from the user interface). |
Personalization | The processing of personalized requests, or parts thereof, involving an XSL transformation. |
Request Handling | The processing of regular requests. |
Media queries | The retrieving of content for dynamic content overviews. |
Regular rendering | The rendering of content that could not be retrieved from the cache. |
Cache access | The loading of data from the physical disk cache, the memory cache or the timestamp database. |
Friendly URL resolving | The resolving of friendly URLs. |
Requests per Second vs Request Duration
This statistic plots the average duration of a request against the number of requests per second.
