I know this is not really a Cisco specific question but it is definitely in support of Cisco hardware.
How do most of you folks prove that "the problem" is not the network? We utilize CA Spectrum and eHealth for availability and statistical analysis but in some instances that does not cut it. We don't typically have much trouble proving that a T1 is serving up 1.5 meg of bandwidth. Customers complain that their access is slow, we show that they are using all available bandwidth and eventually sell them more bandwidth and the problem is resolved. The more difficult effort is when there is plenty of available bandwidth and a particular application is slow (Outlook in the case I am involved in now). This is a very high level political official and we must come to a resolution. All tools we have available to us today indicate that there is not a problem with the network. Typical utilization on the T1 is about 500 to 600K peak during the day. Certain management continues to point the finger at the network. We have used Internet based speed tests that at times show less than 1.5Meg download speeds, I explain the variables in the Internet and the particular tool in use as well as local contention for the bandwidth etc to no avail, once they see less than 1.5 meg speed the finger points to the network. I still must somehow "prove" that the network is not the issue. I am interested in an Internet speed test like tool to install at the core of our network that would provide a sustained upload or download test that would run for longer periods of time than a regular speed test. I would like to fill the pipe while graphing in Ehealth or as part of the selected tool to prove that the contracted bandwidth is available in both directions. Any recommendations for products would be appreciated. We are currently looking at SolarWinds WAN Killer and a traffic generator from Omnicore LanTraffic V2. I am also open to different "types" of solutions to point to where the problem is actually located.
