send events as syslog without an additional agent

Based on the searching I have done so far, I may be asking for the impossible...but it's worth a shot:

I have a ton of Windows based servers in my environment (primarily Server 2008 R2 and Server 2012 R2). The bulk of them are virtual machines (hosted on VMware esxi). All of them have Microsoft System Center agents installed on them.

I have been tasked with trying to send all Windows event log entries to a SIEM (specifically Sagan from Quadrant) in a syslog format, without using an additional agent on each guest OS.

I would like to hear from anyone that has a creative solution to meet that need. It could include somehow using the existing vmtools or System Center agents to collect the logs and send them off. Honestly, it could also include sending the event logs to Sagan without being in the syslog format, as long as Sagan will support it. Effectively, if you can get event entries from a Windows OS to Sagan with no agent; you'll get points.

Thanks in advance for any help!

Though I am not into Sagan but other SIEMS typically will need some sort of logger agent otherwise the remote query either via WMI or even having the powershell (like Get-Eventlog and Send-MailMessage ) in windows to send out via email or csv for further analysis ...the agent is normally recommended...Splunk suggested
There are two main ways to proceed:
• Set up forwarders locally on each Windows machine from which you want data. These forwarders can send the Windows data to the non-Windows receiving instance of Splunk.
• Set up a forwarder on a separate Windows machine. The forwarder can use WMI to collect data from all the Windows machines in the environment and then forward the combined data to a non-Windows receiving instance of Splunk.
... and if Windows even subscription via "wevtutil" ( or "winrm" which the functionality depends on the Windows Remote Management (WinRM) service and the Windows Event Collector (Wecsvc) service. (

Pardon me but overall do not see much traction for "agentless" in most environment ... the below sum up otherwise but probably (and since this is a VM environment) VMware Insight can be explored

Repeat after me:
Windows does not support syslog

Which means that you need one or other kind of agent to convert windows logs.
