The VMware vCenter Server Appliance acts as a syslog server, receiving system logs from hosts provisioned with Auto Deploy. You can change the system and SSL ports on the VMware vCenter Server Appliance to which hosts provisioned with Auto Deploy send log files.
On the Services tab, click Syslog.
Type the Syslog collector server port and the Syslog collector server SSL port and click Save Settings.
Hosts provisioned with Auto Deploy send log files to the specified ports. Although the VMware vCenter Server Appliance acts as a syslog server, it does not appear as a syslog server in the vSphere Client.
You must restart ESXi services for these changes to take effect.
