Description
Without establishing what types of events occurred, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack. Satisfies: SRG-OS-000037-VMM-000150, SRG-OS-000063-VMM-000310

ℹ️ Check
From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Advanced System Settings. Select the "Config.HostAgent.log.level" value and verify it is set to "info". or From a PowerCLI command prompt while connected to the ESXi host, run the following command: Get-VMHost \| Get-AdvancedSetting -Name Config.HostAgent.log.level If the "Config.HostAgent.log.level" setting is not set to "info", this is a finding. Note: Verbose logging level is acceptable for troubleshooting purposes.
