Troubleshoot Path Changes via Runbook Automation

You can verify application paths in a runbook and run Qapps, CLI command, or other automation to troubleshoot upon path changes.

Note: The steps below assume you have basic knowledge of the NetBrain Runbook function.

1. On a map, open a runbook and add a Verify Application node to the runbook.
   

   Note: The applications are ordered by weight from high to low.

2. Click the Verify Application node and add the application paths.
3. Click Run to calculate and verify the paths.
   
4. Right-click a verified path with changes and draw the path on a map.
5. Add Qapps or other actions you want to run for the application paths.
   

Application Weight

When you select paths to add them to the Verify Application node of a runbook, the applications will be listed and sorted by weight from high to low.

The weight of an application is the sum of device weight and path weight.

• Device Weight: The device weight of an application is the sum of the weights of all devices involved in the application. When assigning devices to an application, you can manually assign a weight to each device.
  
• Path Weight: The path weight of an application is the sum of the weights of all the paths contained in the application. For example, APP1 has two paths, and the weight of Path1 is 3, the weight of Path2 is 5, then the path weight of the App1 is 8.

The weight of a path depends on how many devices the path crosses have appeared on a map, and one device weighs 1. For example, if a path crosses 5 devices, only 3 of 5 appear on the map, and the path weight is 3.
