In Horizon Client 3.1 and later, Horizon Client generates log files in the ~/Library/Logs/VMware Horizon Client directory on the Mac client. Administrators can configure the maximum number of log files and the maximum number of days to keep log files by setting keys in the /Library/Preferences/com.vmware.horizon.plist file on a Mac client.

Maximum number of log files. The maximum value is 100.


Maximum number of days to keep log files. This value has no limit.

Files that do not match these criteria are deleted when you launch Horizon Client.

If the MaxDebugLogs or MaxDaysToKeepLogs keys are not set in the com.vmware.horizon.plist file, the default number of log files is 5 and the default number of days to keep log files is 7.
