info needed on syslog server

Hi All,

I have two questions that I am unable to understand ---

First >>>> I followed article http://medkorp.com/DoTheJob/how-to-install-and-configure-vmware-syslog-collector-5-1/ and configured syslog server on the Virtual center Server.

I am able to see a file called syslog for my hosts. Which type of logs this file has ???

Second >>>>> I want to redirect log files from the ESXi host to a datastore. All the log files which are in /var/log in an esxi host to a datastore --- how can I do this?

thanks

Vaibhav
