Warnning on Esxi Server "System logs are stored on non-persistent storage"

To verify the location:

1. In vSphere Client, select the host in the inventory panel.
   
2. Click the Configuration tab, then click Advanced Settings under Software.
   
3. Ensure that Syslog.global.logDir points to a persistent location.
   
4. The directory should be specified as [datastorename] path_to_file where the path is relative to the datastore. For example, [datastore1] /systemlogs.
   
   
5. If the Syslog.global.logDir field is empty or explicitly points to a scratch partition, make sure that the field ScratchConfig.CurrentScratchLocation shows a location on persistent storage.
