Viavi Observer and Apex are monitoring and packet capture solutions designed to tell you how well applications are being delivered across your network. The main complaint from users is that “things are running slow” which means you need to measure response times to understand this.

Using their proprietary metrics Apex from Viavi can monitor the timings for each of key elements (network, server, application) and establish which one is at the route cause of your problem. The Observer software can be used on a laptop to gain more detailed insight into packet captures, looking at the different layers and TCP issues to get a more thorough understanding of what your packets are trying to tell you.
