How to use

The commands ( allow you to set a remote syslog server for an ESXi 3.5 host. This command will not work on ESX 3.5 hosts. If you connect via a VirtualCenter host with the –server option, you must then specify the ESXi host with the -h/–vihost <host> option. Once the settings are configured, there is no need to start or stop the syslog agent.

To show current syslog configuration use this command. –server <server_name> -i or –server <server_name> –show

To set the port for the syslog server use this command. –server <server_name> -p <port> or –server <server_name> –setport <port>

To set the hostname or IP for the syslog server use this command. –server <server_name> -s <syslog server> or –server <server_name> –setserver <syslog server>

The below image displays some sample messages sent from an ESXi host and the amount of messages sent in a short time frame can be quite large.

It is possible to set the syslog server and port from within the VI client. With the VI client (but not the command) it is also possible to configure ESXi to write syslog messages to a text file on a VMFS datastore that the ESXi host has access to. This is shown in the below image. It is necessary to format Syslog.Local.DatastorePath value as [<datastore_name>]/<folder_name>/<file_name>. Folder_name is optional.
