The Z-Ray History page is used for postmortem review of all requests made to the Web server, including non-browser based requests, such as: APIs, Web services, PHP-CLI and mobile requests.
All the information recorded by Zend Server and displayed in Z-Ray, such as request execution time, events, exceptions, errors, database queries, functions, and more, can be viewed in one centralized location.
Tracking for these requests is commenced as soon as the page loads, and kept in a database for later review.
Z-Ray functionality on this page depends on the set Z-Ray access mode.
In Enabled Mode - all requests made to the Web server are collected.
In Secured Mode, only requests using an access token are collected.
In Disabled Mode - all request information is not collected.
For more information on Z-Ray access modes, see Enabling/Disabling Z-Ray.
