Generating Horizon Event Log Messages in Syslog Format Using the ‑I Option

You can use the vdmadmin command with the -I option to record Horizon event messages in Syslog format in event log files. Many third-party analytics products require flat-file Syslog data as input for their analytics operations.

Syntax


vdmadmin -I -eventSyslog -disable

vdmadmin -I -eventSyslog -enable -localOnly

vdmadmin -I -eventSyslog -enable -path path

vdmadmin -I -eventSyslog -enable -path path 
 -user DomainName\username -password password  

Usage Notes

You can use the command to generate Horizon event log messages in Syslog format. In a Syslog file, Horizon event log messages are formatted in key-value pairs, which makes the logging data accessible to analytics software.

You can also use the vdmadmin command with the -I option to list the available reports and views and to display the contents of a specified report. See Listing and Displaying Reports of Horizon Operation Using the ‑I Option.

Options

You can disable or enable the eventSyslog option. You can direct the Syslog output to the local system only or to another location. See "Configure Event Logging for Syslog Servers" in the Horizon 8 Installation and Upgrade document.
