Fix Recommendation

From the vSphere Client, go to Hosts and Clusters.

Select the ESXi Host >> Configure >> System >> Advanced System Settings.

Click "Edit". Select the "Syslog.global.logDir" value and set it to a known persistent location.

An example is shown below, where 51dda02d-fade5016-8a08-005056171889 is the UUID of the target datastore:

/vmfs/volumes/51dda02d-fade5016-8a08-005056171889

or

From a PowerCLI command prompt while connected to the ESXi host, run the following command:

Get-VMHost | Get-AdvancedSetting -Name Syslog.global.logDir | Set-AdvancedSetting -Value "New Log Location"

Check Contents

From the vSphere Client, go to Hosts and Clusters.

Select the ESXi Host >> Configure >> System >> Advanced System Settings.

Select the "Syslog.global.logDir" value and verify it is set to a persistent location.

If the value of the setting is "[] /scratch/logs", verify the advanced setting "ScratchConfig.CurrentScratchLocation" is not set to "/tmp/scratch". This is a nonpersistent location.

If "Syslog.global.logDir" is not configured to a persistent location, this is a finding.

or

From a PowerCLI command prompt while connected to the ESXi host, run the following commands:

$esxcli = Get-EsxCli -v2
$esxcli.system.syslog.config.get.Invoke() | Select LocalLogOutput,LocalLogOutputIsPersistent

If the "LocalLogOutputIsPersistent" value is not true, this is a finding.
