URL Insight
Zend Server helps you get an accurate picture on how your application and server are performing by allowing you to view detailed reports on critical requests for PHP pages located on your Web server. Monitor the most time consuming and most frequently visited URLs on your Web server, or view those requests with the slowest response time.
In addition you can use periodically taken snapshots of Z-Ray to drill down further into a request. See the queries made to the database, profile functions or see if there were any errors or events triggered by the request at that specific point in time.
Note:
To ensure optimized performance, Zend Server only takes Z-Ray snapshots of URLs tracked by URL Insight. URLs not included in any of the reports are ignored.
