Why monitor from the users perspective?
Even if each component and infrastructure level that make up a complex transactional Web site operates correctly on its own, it is possible that the performance of the overall, integrated system will be less than optimal. The most effective way to measure the overall performance of your website is to monitor the ability of end users to perform the specific activities that the site supports. If the intended user of the system is able to perform such activities, the site has fulfilled its purpose. On the other hand, if a significant portion of end users (or their attempts) fail, the system’s performance is inadequate. Vertain monitors your site by exactly duplicating the activities of end users through a standard Web browser that measures how well the server responds. As a result, the data we collect accurately reflect the quality of the experience of the users.
