Visual Network Troubleshooting

A map-driven approach to solving complex network issues

No matter how skilled the troubleshooter, quick access to key network information is critical. In order to properly diagnose a network problem, engineers usually look for answers to three critical questions:

  • 1
    How's the network configured?
  • 2
    How’s the network performing?
  • 3
    What changed to cause the problem?

Today, most engineering teams lack up-to-date and reliable documentation and rely primarily on the command line interface (CLI) to access this information. This approach forces engineers to collect data one command at a time - for a single device or interface.

As critical as the network is, troubleshooting is a largely manual and time-consuming process.

Diagnose Network Issues Visually with NetBrain

NetBrain is a map-driven network automation tool. A diagram of the network, rather than a telnet window, serves as the primary troubleshooting interface. Through the map, engineers have access to rich design information, live performance metrics, and a comprehensive baseline of historical network changes. This information supports an effective and automated troubleshooting methodology:

Deep Network Discovery Instantly Map the Problem Area

NetBrain offers an on-demand approach to network diagramming. Rather than fumbling around for the right diagram, engineers can generate diagrams in real-time, tailored to the task at-hand. In the event an engineer is troubleshooting a slow application, a map of the application flow can be built in seconds. These ‘dynamic diagrams’ are embedded with rich design data, accessible by simply zooming into the map.

Dynamic Network Mapping Automate Performance Analysis

NetBrain’s live monitoring capability allows engineers to visually analyze key performance parameters through a ‘HeatMap’ view of the network. This view overlays unique network data, such as interface errors or routing statistics over the topology diagram, depending on the monitoring profile selected. Several monitoring profiles are built-in to diagnose congestion, interface issues, VoIP traffic, and much more. The performance data collected is automatically embedded within the dynamic map and is saved there for later review.

Visual Monitoring Automate Historical Analysis

Studies show that nearly half of all network outages are caused by a network change. Tracking down what’s changed can take hours of guesswork without the right tool. NetBrain leverages historical network data, collected through recurring benchmarks, to highlight changes automatically. Engineers can instantly compare the current baseline to a previous baseline and find changes in configuration, routing, spanning-tree tables, and more. By expediting their ability to spot changes, engineers are better equipped to target the root cause of an issue.

Automation Procedures Drill-Down with Automation Procedures

NetBrain includes hundreds of built-in diagnoses to troubleshoot issues ranging from spanning-tree to multicasting. If those aren’t enough, engineers can leverage NetBrain’s visual programming environment to customize their own repeatable troubleshooting logic. NetBrain’s Automation Procedures don’t require any scripting; engineers can define executable logic through flow-charts and sample CLI data. Automation Procedures are launched directly from the map to diagnose an entire network segment instantly, rather than one device or interface at a time.
