Placed in the upper left section of the console, the Network Overview pane shows the network, which in the demo consisted of two Cisco 2951 routers, two Ubuntu Linux machines, and several small applications. The center panes, meanwhile, display server and router CPU use, while the charts on the right show average receive and transmit traffic flow for all interfaces configured on the two connected routers.

Whateley simulated the shutdown of Router 1. In the Network Overview pane, both the router and its connection to the computer went red to indicate the problem, as did the connection to Router 2 when it failed as well.

"All networking tools can do that," Whateley said, but explained that what surprised the audience at Cisco Live was "the speed with which we could react to that behavior, which we can do because we're using the onePK interface and monitoring the actual interfaces on the device," allowing the software to provide an immediate notification when an interface goes down.

Whateley then called my attention back to the Network Overview pane to demonstrate the simplicity of app monitoring in the software. DemoApp1's icon was yellow, indicating an issue.

He brought up the app's log file, through which administrators can perform both simple and complex interactions with the app, and resolved the issue, restoring the app to its blue, normal state.

To demonstrate the effects of a jump in traffic, such as what the network might experience if someone performed a large backup over a network link, Whateley sent a flood of 200,000 10K packets out from the DemoApp1 client. The app's data consumption spiked, as the lower left pane of the console showed. Server and router CPU load spiked as well, changing in real time as the traffic flowed. Interestingly, the software revealed a CPU spike about twice as high on Router 1 as on Router 2. "We think it's because they have different versions of the OS on them," he explained, pointing out that with this view, "you can isolate and tell exactly where your problem is right away."

The software offers myriad additional options to dive deeper into the information and analytics flowing from various interfaces, offering a granular as well as a broad view of the network. And what it all adds up to is the ability to enable greater responsiveness to issues on the network.

"There are a lot of monitoring tools that will look at network interfaces and tell you things like, 'This is the most congested interface.' But is that the most business-relevant thing to ask? Just telling you it's congested isn't business-relevant," Whateley said.
