We had no way of identifying where the problem occurred. We didn't have very good information, and user experience and application performance were somewhat of a mystery to us.

In our case, we monitor both our internal and external traffic, and found that if we installed it on one of our internal network switches, we could monitor the traffic from both.

We wanted a tool that was not intrusive and was able to monitor the end-to-end experience.

We use it for monitoring individual applications, enabling us to improve problem resolution for users who are reporting problems and efficiently identify the root cause.
