I have just started using the vSphere 5 Syslog Collector and I have pointed all my ESX hosts at it. After about a day, I applied some Windows patches to the server running the syslog collector and rebooted it. After that the ESX hosts stopped logging to it.
I created a powercli script to reload the syslog daemon on all the ESX hosts, and most of them started to log to the syslog collector again. There are still some that aren't logging to it.
Does anyone use the vSphere Syslog Collector and know of any issues with it. Or if there's something that needs to be done on it or the ESX hosts to ensure they continue to send log information to the syslog collector.
All my hosts are running vSphere 5.0, but the Syslog Collector is vSphere 5 Update 1
Any help / thoughts would be greatly appreciated.
