VMware Horizon creates log files that record the installation and operation of its components.

Note: VMware Horizon log files are intended for use by VMware Support. In VMware Horizon 8 deployments, VMware recommends that you configure and use the event database to monitor VMware Horizon. For more information, see the Horizon Installation and Upgrade and Horizon Administration documents.
