ESXI-67-000004 - Remote logging for ESXi hosts must be configured.
Remote logging to a central log host provides a secure, centralized store for ESXi logs. By gathering host log files onto a central host, it can more easily monitor all hosts with a single tool. It can also do aggregate analysis and searching to look for such things as coordinated attacks on multiple hosts. Logging to a secure, centralized log server also helps prevent log tampering and also provides a long-term audit record. Satisfies: SRG-OS-000032-VMM-000130, SRG-OS-000342-VMM-001230, SRG-OS-000479-VMM-001990
From the vSphere Client, select the ESXi host and go to Configure >> System >> Advanced System Settings. Click 'Edit', select the 'Syslog.global.logHost' value, and configure it to a site-specific syslog server. or From a PowerCLI command prompt while connected to the ESXi host, run the following commands: Get-VMHost | Get-AdvancedSetting -Name Syslog.global.logHost | Set-AdvancedSetting -Value '<syslog server hostname>'
