Network Physics' NetSensory Enterprise Architecture 5.0

With the new Insight view components, Enterprise Architecture 5.0 promises to ease drilling into network management. But does it live up to its claims?

Application Scanning

As soon as I plugged the appliances into the network, the NetSensory architecture scanned for applications. It identified well-known ports, searched for server applications requiring a range of ports, and sought out user-defined applications that use ports, servers and URLs in combination.

Once the network is defined and the applications are identified, the NP-2000s collect network- , server- and application-performance data much like an RMON probe does. This method requires no agent and uses little overhead.

The NP-Director server aggregates the data and presents it on the Java interface. Trouble is, with so many drill-down options, you'd have to be a network engineer to know where to begin. For this reason, Network Physics has added five predefined, customizable NetSensory Insights views--Audit, Baseline, Optimize, Troubleshoot and Security--to organize the performance data for you.

Good

• Built-in network engineering smarts• Customizable Insight template views• Data remains close to the source

Bad

• Upgrading requires too much hands-on time• Client-screen updates must be asked for

Added Insights

Audit Insight displayed a performance view of applications, servers and clients. The discovery parsed packets on the wire and found all traffic going to and from the Syracuse labs, as well as critical servers and a mess of clients.Next, I examined Baseline Insight, which breaks out trends monthly, weekly or daily, depending on how you configure it. It showed me performance statistics for nodes with the highest bandwidth usage, the most latency and the greatest packet losses.

Optimize Insight displays chatty applications. It lets you compare their performance before and after a change by selecting key statistics, such as payload and packet rates.

Troubleshoot Insight identifies bandwidth hogs and slow servers. Security Insight uses traffic patterns to look for worms.

Sharing With Others

This version of NetSensory has a read-only option for Insights, letting service desk and management folks log in to check out designated performance data. All NetSensory screens can be e-mailed outside the company.Overall, Insights improve NetSensory by making it easier to combine and compare information. But for network diagnostics, you'll still need someone smart running the show.
