Each ESXi host runs a syslog service that is used to log VMkernel messages, as well as messages from other system components, to a set of log files.
Syslog settings may be modified using the vSphere Web Client.
To do so:
- Using the vSphere Web Client, navigate to an ESXi host in the inventory.
- Go to the Manage tab and select the Settings button.
- Choose Advanced System Settings underneath the System section.
- Search
syslogin the query section, as demonstrated in the following screenshot:
- The following syslog values may be changed:
Syslog.global.defaultRotate: This setting specifies the maximum number of logs to keep.Syslog.global.defaultSize: This setting specifies the default size of a log, in KB, before a log is rotated by the system.Syslog.global.LogDir: This setting specifies the directory in which logs are stored. This can be an NFS or VMFS datastore.Syslog.global.logDirUnique: This setting creates a unique subdirectory with the name of the ESXi host.Syslog.global.LogHost: This setting specifies the remote host and port where syslog messages are forwarded.
- To modify a syslog value, select the Name in the list and click on the Modify (pencil) button.
- The following screenshot demonstrates modifying the
Syslog.global.defaultRotateoption.
- Once the value has been modified as desired, click on OK.
- Repeat steps 5-8 as needed.
