Response time monitoring for AJAX and Javascript

[Updated 10/31, 7:50pm central] John Newsom, VP of our APM (Application Performance Monitoring) team has had a great overview of the issues and challenges around Web 2.0 monitoring published in The DataCenter Journal. He discusses the three main issues

• Inadequate code-level analysis
• Incorrect page response times
• Insufficient context

and the key ways you can address application monitoring, including 1. Capturing functional issues and establishing context; 2.Capturing and troubleshooting JavaScript errors; 3. Looking for detailed insight into page load times; and finally, 4. Isolating problems to individual page elements.

Overall its a great read and served as a great refresher for a couple of issues I’m currently looking at in one of my projects. CTR (Computer Technology Review) has a good fly-by of the Foglight APM.
