Windows Eventlogs to Syslog

Because central logging is so awesome and widely used in the Linux/Unix world, I want to show you a way how you can also gather Windows Event Logs through the good old Syslog Server.

  • On the server side, its quite simple: Use the plain vanilla Syslog or use something with Syslog capabilities (e.g. Rsyslog or even better Splunk).
  • On your Windows System, get eventlog-to-syslog (, put the two program files in C:\Windows\System32 and install it as a service as described below:
    C:\Users\administrator>evtsys -i -h <SYSLOGHOST>
    Checking ignore file...
    Aug 23 20:27:25 HOSTNAME Error opening file: evtsys.cfg: The system cannot find
    the file specified.
    Aug 23 20:27:25 HOSTNAME Creating file with filename: evtsys.cfg
    Command completed successfully
    C:\Users\administrator>net start evtsys
    The Eventlog to Syslog service is starting.
    The Eventlog to Syslog service was started successfully.

Here are the options for eventlog-to-syslog:
