What are its limitations? Some network monitoring tools can generate traffic as part of the test process, but OmniPeek Enterprise is entirely passive -- it monitors only real traffic instead of traffic generated just for a test. In some cases, generating test traffic is an advantage because you can test unusual conditions such as heavy congestion at a certain time of day or from one particular department. Also, for multiple locations, network data is collated for multiple network segments, which can add some complexity for figuring out how to configure those segments.
What do customers say? "OmniPeek Enterprise allows all of us to pinpoint performance issues quickly in an automated fashion, eliminating a significant amount of time required with manual network-troubleshooting exercises," says Vince Humes, director of technology solutions for the Northwest Tri-County Intermediate Unit, an IT help desk that supports 19 school districts in Pennsylvania.
