Number of references to test
This configuration parameter defines the maximum number of references that will be tested in a HTTP Full-page test. For example if the monitored page contains references to a 100 external components like images, styles, links to different pages etc and this value is set to 50, only the first 50 components will be tested.
At the advanced configuration page you can specify which components should be tested. For example if you want to monitor only the time needed to load the complete page you might choose not to test external links. If you want only to check for dead links without monitoring the time needed to download every object you should select the "Check availability" option for all component types.
