ESXi 5.1 syslogs and QRadar

I'm trying to have one of my hosts send syslogs to QRadar, however the instructions I find online are slightly different and seem to be for ESXi 4.1.

That said it seems the settings I need to change are:

SYSLOG.GLOBAL.LOGDIR - which I've entered: []/scratch/log/messages

and

SYSLOG.GLOBAL.LOGHOST - which I've entered the IP address of QRadar with and without :514 added to the end.

But I can't seem to get the logs sent to QRadar. Anyone have any experience with both ESXi 5.1 and QRadar and can provide assistance would be appreciated.
