Analyzing a network issue usually requires multi-stage troubleshooting procedures to narrow down the device scope, and finally locate the problematic device.

A Gapp connects two or more single Qapps together in a logic manner. Data and devices can be transferred and filtered between two Qapps. A downstream Qapp in a Gapp can be set to run on which devices based on the alerts of its upstream Qapp. You can run a Gapp to narrow down the device scope, and finally locate the problem device when troubleshooting network problems.

Example: Use a Gapp to troubleshoot OSPF Neighbor State.

This chapter introduces elements of a Gapp and how to create Gapps to automate your network task. The following topics are covered:

▪Creating a Gapp
