Dynamic diagrams are created on-demand, instantly. Because they are data-driven from the live network, they are always up-to-date. Through this approach, there’s no need to create and maintain a database of drawings.

Notes de l'éditeur
- Generation 0: Perl, Expect/TCL, and later python scripting used to automate Inventory collection and perform some basic health checks. Parsing the resulting data was often complex and performed by a programmer rather than a network engineer who spoke different languages. Generation 1: Change and configuration management resulted in more available historical data and easier deployment of changes to multiple devices in the network. Network inventory tracking was commoditized as was configuration comparison. Generation 2: The challenge is that manual scripting and change/configuration management are valuable, but limited to specific user who can do it, or use cases that were covered by what a vendor had released. CLI data-mining, network analysis, and troubleshooting are largely left to repetitive CLI executions, whiteboard drawings, or newer NMS tools that provide limited use to higher level engineers.
- Even with a smaller diagram, determining the actual path through the live network can be an onerous task, as can be troubleshooting the issue once the path is known: Start Confirm a device and interface that is next in the path on a static map. Login to the device Execute device health commands Run specific CLI commands Re-run the CLI commands, then stare and compare at the results until a change is detected or assumed non existent. Repeat NetBrain automates the path determination process, using live device data to visually map the path, leaving on relevant components and interfaces on the map. Then, using Qapps, a set of CLI commands can be run across the entire path, at once, with deltas automatically calculated and displayed on the map as appropriate. Further enhancing the operators efficiency, visual alarms and map annotations can be created by Qapps drawing attention to problem areas while maintaining the context of the map.
- 1st Generation: Static Visio diagrams were very long and tedious to complete. They required Visio experts and top level engineers to design. This resulted in network diagrams being built as a one-size-fits all. In the event that devices in question were in 2 separate sets of static documentation, an engineer would be required to “stitch” the connections between the maps manually. 2nd Generation with Auto-Discovery improved the speed at which the documentation was created, and lessened the need for experts to be fully engaged through the process. This resulted in more maps being created with an often “narrower” focus. Admins were leveraged since each map became more complex to build, and the scale of the tooling came into question. Even though a larger variety of diagrams could be built, the user was still limited to what was “on the rack”. Manual stitching of diagrams was still required. 3rd Generation Dynamic Maps: Using detailed device data to model the network on a map in real-time, virtually eliminates the need for static documentation altogether. It is extremely quick and in many cases, (eg. If 2 end-points are known), the entire relevant path can be mapped out in seconds. Traffic path and neighbor extension eliminate the need for manual stitching of multiple maps since, all relevant components along the path can be built easily. The “ease of use” opens diagrams to any operator at almost any level, and provides a “custom fit” option for whatever the user needs. IE. If its not on the rack already, build it in seconds based on current network state or a historical version. Dynamic maps also create true single pane of glass since each component on the map is a live element that can present operation and configuration data with alarms and thresholds.
- Whiteboards are a very common tool for discussions but there are 2 common problems. Artistic Capability. What an Engineer sees in their mind is not translated well to a whiteboard. Even if the drawing is drawn well, discussions across the meeting often leave the drawing in a state where no-one else who was not part of the discussion could interpret it. NetBrain uses common icons that are familiar and allows the user to annotate the map with text and various advanced protocol highlights that make the illustrations clean. Timelessness: Even those who attending the discussion session will find it very difficult to decipher a photo taken of the whiteboard drawing. NetBrain embeds map data, including notes, to improve the timelessness of the drawing. Because live and modelled data can be accessed via the Workstation Client, future discussions can benefit from map regeneration and historical comparison.
- The design reader offers an advanced method of viewing a device configuration file. Instead of executing show running-config and paging through the configuration to find interested information, NetBrain automatically parses the configuration into various configuration blocks. In many cases, associated configurations are shown together. For example, if an ACL is used in a distribute-list for EIGRP, the ACL is included as part of the configuration block so all information is in front of the operator.
- Searching relevant maps helps save time since another operator has already taken the time to extend neighbors and lay-out the map. This map might be exactly what the current operator is looking for. By zooming out on the map with minimal devices, NetBrain will automatically search all indexed Qmaps and Visio documents for maps that contain all or some of the devices on the current Qmap. Once a desired map is found, simply select it, and a new tab will be opened with the appropriate map.
- Picture: Provides a stock image for most devices. Clicking the setting wheel, allows the user to insert their own images and visio diagrams. Useful in support cases where an operator has never been to a location and needs to navigate a technician to a device. Floor plans, rack elevations, pictures of the front and back of the device, and cabinet can all be included. Performance: Check live device CPU/Memory and Interface statistics Design: Click Refresh on the Design card and only configuration items that are on the device will be displayed. Offers a quick way to get an overview of the device. Clicking on a configuration block, automatically launches the full Design Reader for the device

- With NetBrain’s Qmap, all troubleshooting activities remain in the context of the problem area on a map providing a True Single Pane of Glass. CLI results can be parsed and the appropriate information displayed directly on the map, and/or the user can view full historical raw data. Chart and Monitor data is easily customizable and again, displayed without leaving the context of the map. Work flow is focused and even previous monitor results can be displayed on the map during post-mortem type discussions.
