Client are effective immediately. However, most settings you define by using ESXCLI require an
additional command to take effect. For more details, see ESXi Syslog Options.
ESXi Syslog Options
You can define the behavior of ESXi syslog files and transmissions by using a set of syslog options.
Apart from the base settings, such as Syslog.global.logHost, starting from ESXi 7.0 Update 1,
a list of advanced options is available for customizations, and NIAP compliance.
Note All audit record settings, beginning with Syslog.global.auditRecord, take effect
immediately. However, for other settings that you define by using ESXCLI, make sure to run the
esxcli system syslog reload command to enable the changes.
