I have add my ESXi hosts into OBS, using SNMP which works.

I have then tried to add OBS as the remote syslog server with udp://osserver:514 as the link in the Syslog.global.logHost option in Advanced System Settings for each of my ESXi hosts...  The host names and IP  are defined in OBS.  (and I have other syslog hosts reporting, so I know it works for other hosts)...  but I get nothing from the ESXi servers... I have tried to trigger different things, but I get nothing... 

Also I have tried to add the OBS server in the syslog option on the vCenter Appliance Server...  I can do a test which vCenter tells me is send OK, yet I get nothing on OBS.. This might be because the vCenter Appliance is virtual and is not added to OBS as a host (not sure if you even can, because it does not support SNMP...) ?  But it would be great to It was possible to add it... 

I know this is two problems, yet it is related and maybe someone has tried to set this up?
