Enable DEBUG logs on VMWare Horizon Agent

Typically, when working with the EUC/VDI solutions, the EUC admins and support professionals will have to troubleshoot agent connectivity and performance-related issues. To troubleshoot such scenarios, you will need the DEBUG logs. By default, DEBUG logging level is not enabled, so will have to enable DEBUG logging on the Horizon agent. Will see how we can enable that. 

  • First, browse the VMware Horizon Agent installation utilities directory (DCT)

C:\ProgramFiles\VMware\HorizonAgents\DCT>

  • Then, run the command support.bat loglevels to see the available logging levels

C:\ProgramFiles\VMware\HorizonAgents\DCT> support.bat loglevels

  • You will be presented with the available log levels

  • After reviewing, please select the desired log level (DEBUG) – option 2

  • Finally, to generate the log bundle run the batch file. So that it will generate a ZIP file on the Windows Desktop system. 

Configuration rollback on Cisco Nexus devices

Configuration rollback is a crucial factor when planning Change Requests (CR/CCR). Cisco devices have a mature approach to this. We already discussed configuration rollback on IOS and IOS XE How to properly rollback configuration changes on Cisco devices Today, we are going to look at Nexus configuration rollback. 

Nexus devices use a feature called “checkpoint“. This feature allows us to take system state snapshots. Will see how we can create a snapshot and then perform a change, after that, we can roll back the configuration. 

  • Creating the checkpoint with a description (checkpoint name and the description are the same [before_change]).

checkpoint before_change description before_change

  • Then, list the checkpoints and verify whether the newly created checkpoint is active with the command show checkpoint all

If you wish to remove the checkpoints, you may use the command clear checkpoint database
