The Summary tab of the ESXi 5.0 host reports the warning: System logging not Configured on host hostname

VMware KB: The Summary tab of the ESXi 5.0 host reports the warning: System logging not Configured on host hostname

• After upgrading from ESXi 4.x to 5.0, the Summary tab of the host reports the warning:
  
  System logging not Configured on host <hostname>

Resolution

To resolve this issue, configure the default logging location in the ESXi host.

To configure the default logging location in the ESXi host:

1. Navigate to Configuration > Software > Advanced Settings > Syslog > Global. 
2. Set the type of the Syslog.global.logDir parameter to []/scratch/log. In this case, the logs reside on the local disk.
   
   Note: If you want to send the logs to a different datastore, set the type of the Syslog.global.logDir parameter to the complete path where you want to store the log files. For example, [Datastore1]/logs. The location of the datastore should be unique to each ESXi host. Do not specify the same log directory to multiple hosts, doing so may result in a crash or kernel panic.
