As an independent troubleshooter, I am always interested in tools that are portable and provide instant information.
Many times when I am looking at a customer’s problem, I cannot assume that they will graciously give me their SNMP strings or access to their network management system. That being the case, RMON and any other flavor of Flow would also be out of the question as well. Honestly, I hope a customer wouldn’t willingly give out that kind of information or access to anyone.
Since my background is protocol analysis, I tend to gravitate to those tools that work from the packet level. Of course I know this isn’t always possible, but I’ll take whatever I can get. And as the old saying goes, “Packets don’t lie”.
In this article I am showing you a quick peek at Colasoft’s (www.colasoft.com) nChronos product which basically captures packets and uses a slick GUI to control how you report on what it just captured.
