Log File Configuration

Horizon Client generates log files in the ~/Library/Logs/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.omnissa.horizon.plist file on the Mac client.

plist Keys for Log File Collection

KeyDescription
MaxDebugLogsMaximum number of log files. The maximum value is 100.
MaxDaysToKeepLogsMaximum number of days to keep log files. This value has no limit.

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

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