Examples described herein include systems and methods for providing network insights on a graphical user interface (“GUI”). The GUI can visualize network errors to help administrative or information technology users more quickly identify issues with an enterprise application. The enterprise application can report network request information to a server. Then the GUI can present visual overlays that compare error metrics between different time cycles of the application. The visual overlay can graphically display these errors on top of one another for immediate relative visualization. Additionally, a grouped list of host destinations can be simultaneously provided. The destination addresses can be abbreviated, and errors grouped accordingly in a manner that provides advantageous error visualization.
