IndicatorDescription
Debugging optionsSpecifies the status of the XperienCentral debug options. If any debug option is enabled, the status is red.
Log levelSpecifies the level of logging that is currently set for XperienCentral. Logging can be enabled for the following system functionality:
  • XperienCentral
  • Jackrabbit
  • Spring framework
  • Quartz
What you log for each and how many of these functionalities you enable logging for can directly affect XperienCentral performance.

Page Response Time Indicators

The Page response tab shows a list of the slowest page response times in milliseconds for pages requested from the website. The page response tab lists two different types of pages:

  • The slowest pages requested by website visitors that were not retrieved from the cache but had to be generated by the Page Generator
  • The overall slowest pages requested by website visitors, both those returned from the cache as well as those generated by the Page Generator

If caching is enabled, when a page is requested, XperienCentral determines whether the page can be returned from the cache (see 1 in the figure below) and returns it; if the page cannot be returned from the cache, it is generated by the Page Generator and returned (see 2 in the figure below):

To enable monitoring for web pages and/or pages generated by the Page Generator pages, select "Monitoring enabled".

 

Note

Notes:

  • These options are not persisted - Monitoring is enabled for the current session only. If the Tomcat server is restarted, these checkboxes are cleared.
  • Enabling page response time monitoring can affect XperienCentral performance. Monitoring should not be constantly enabled.


When these monitoring settings are enabled, the pages returned by the Page Generator that took the longest to generate as well as the pages that took the longest time to load are listed. The pages that appear in the list are those that have been read since monitoring was enabled or since the last time that the list was cleared using the [Clear list] button.

Slowest Pages from the Page Generator

The pages listed in the "Slowest Pages from the Page Generator" list are pages requested from the website that were generated by the Page Generator and not taken from the cache. The pages in this list are a subset of the pages in the "Slowest pages" list and will always appear in the "Slowest Pages" list as well. See the section Lowering Page Response Times for troubleshooting information.

Slowest Pages

The pages listed in the "Slowest Pages" list are the pages requested from the website that took the longest time to load from the cache and/or be generated by the Page Generator. The pages that took the longest time to be generated by the Page Generator are also listed separately in the "Slowest Pages Page Generator" list. See the section Lowering Page Response Times for troubleshooting information.

To view the contents of a page in the list in a separate window, click its URL in the list. This makes it easy for you to quickly view the contents of the slowest pages. The page will display in a separate window.

Note: Not all pages in the list are viewable due to context-related factors. If the page cannot be displayed, a JavaScript error will be returned.

To refresh the list, click [Refresh this page]. To clear the list, click [Clear list]. For information about steps you can take to improve the performance of slow pages, see the section Lowering page response times.
