Purpose

This article provides the locations of various VMware Horizon log files, found in different components within the environment.

Note: This is an informational KB for on-site troubleshooting. When engaging VMware Support, we request full diagnostic bundles to allow a comprehensive review of the issue at hand.

To collect Horizon log bundles, see Collecting VMware Horizon View log bundles.

To upload Horizon logs to a VMware Support Request, see Uploading diagnostic information for VMware.

Resolution

Please Reference Product Documentation for detailed information on Horizon 8
Collecting Diagnostic Information for VMware Horizon

Note: This article references shell folders and shell folder variables. If you have performed a custom installation, your installation may differ and your log files may not be available in the path mentioned in this article.

When you install the Windows-based components, the installation log is created at %TEMP%\vminst.log_date_timestamp.
In addition, an MSI installation log is created at %TEMP%\vmmsi.log_date_timestamp.

Horizon Connection Server and Replica Server

The Connection Server and Replica Server logs reside on the servers themselves.

In the Horizon Connection Server or Security Server host, you can find the log files in one of these locations:

DriveLetter:ProgramData\VMware\VDM\logs

Horizon Connection Server events report Connection Server-related information, such as desktop and application sessions, user authentication failures, and provisioning errors. For more information see Horizon Connection Server Events.

VMware Logon Monitor logs

Logon Monitor logs are located under

Driveletter:\ProgramData\VMware\VMware Logon Monitor\Logs.

Connection Server Backups

You can find the Connection Server backups at one of these locations in the Horizon Connection Server:

DriveLetter:ProgramData\VMware\VDM\backups

Note: By default, the Horizon Connection Server LDAP backups are encrypted.

Unified Access Gateway

For UAG log collection see Collecting Logs from the Unified Access Gateway Appliance.

Horizon Agent logs for Windows

The location of Horizon Agent log files depends on the version of the Windows operating system used.

Horizon Agent log files are found in:

Windows 10 and the previous version:
