Configure Syslog on ESXi Hosts
You can use the vSphere Web Client or the esxcli system syslog vCLI command to configure the
syslog service.
For information about using the esxcli system syslog command and other vCLI commands, see
Getting Started with vSphere Command-Line Interfaces.
Procedure
1 In the vSphere Web Client inventory, select the host.
2 Click Configure.
3 Under System, click Advanced System Settings.
4 Filter for syslog.
5 To set up logging globally, select the setting to change and click Edit.
Option Description
Syslog.global.defaultRotate Maximum number of archives to keep. You can set this number globally and for
individual subloggers.
Syslog.global.defaultSize Default size of the log, in KB, before the system rotates logs. You can set this
number globally and for individual subloggers.
Syslog.global.LogDir Directory where logs are stored. The directory can be located on mounted NFS or
VMFS volumes. Only the /scratch directory on the local file system is persistent
across reboots. Specify the directory as [datastorename] path_to_file, where the
path is relative to the root of the volume backing the datastore. For example, the
path [storage1] /systemlogs maps to the
path /vmfs/volumes/storage1/systemlogs.
