Installation guide

5 In the Syslog.Local.DatastorePath text box, enter the datastore path for the file to which syslog will log
messages.
The datastore path should be of the form [<datastorename>] </path/to/file>, where the path is relative to the
root of the volume backing the datastore. For example, the datastore path [storage1] var/log/messages
would map to the path /vmfs/volumes/storage1/var/log/messages.
If no path is specified, the default path is /var/log/messages.
6 In the Syslog.Remote.Hostname text box, enter the name of the remote host to which syslog data will be
forwarded.
If no value is specified, no data is forwarded.
7 In the Syslog.Remote.Port text box, enter the port on the remote host to which syslog data will be
forwarded.
By default, this option is set to 514, which is the default UDP port used by syslog. Changes to this option
take effect only if Syslog.Remote.Hostname is configured.
8 Click OK.
Changes to the syslog options take effect immediately.
Export Diagnostic Data
You can export all or part of your log file data.
When you export log file data, the vm-support script creates a file of the selected data and stores it in a location
you specify. The default file type is .txt if no other extension is specified. The file contains Type, Time, and
Description.
Procedure
