Niksun netvcr 2005 manual

In a production environment, use of a full-duplex tap is recommended. The interface is driven via a Java applet and is a good blend of function and style without being too cluttered. That said, there are a lot of functions available, and initial navigation through the interface is slightly daunting. As data comes across the wire, the NetVCR catalogs and organizes the packets into the internal database.

This database is proprietary to Niksun and uses as much of the available space on the appliance as possible. NetVCR sees data sets within the Web interface as interfaces, whether physical interfaces or time segments of captured data. This convention allows for easy data mining within the appliance and is simple to manage. After I had the appliance up and running for an extended length of time, I began configuring automated reports.

In approximately 15 minutes, I set up the NetVCR to e-mail me nightly network traffic reports, with graphs and data on everything from the top protocols in use and the top host interactions, to the busiest and slowest servers measured by average response time. Reporting data choices are extensive, but the interface to configure reporting options suffers slightly due to the vast amount of available report elements.

I chose a PDF report, which was well laid out and provided quick, direct links from the table of contents to the relevant data.

Below the graph is the raw data, showing each server by IP and DNS name, as well as each protocol and the number of connections seen. This capability comes in very handy, as it allows an administrator to create custom reports that first focus on potentially problematic network segments or hosts and then show only the data relevant to that specific entity. When trying to determine the cause of intermittent network problems, this is a powerful tool.

Because the NetVCR captures and stores all the packets seen on the wire, you get easy, complete access to historical data. Plus, Niksun takes the NetVCR beyond protocol analysis by implementing options packages as simple add-ons. In this manner, you can gather specific data on network applications such as VoIP. The scope of the reporting and analysis engines within the UI is broad, and the data it collects is quite useful.

If you need to know everything about your network, take a good look at the NetVCR.
