Alright, back to the task at hand. When I first started working here, about a year ago, the server performance was abysmal at best. That led me to start looking at what was dragging the server down, besides being a Windows box that is. One of many, many, findings was the Event log files were not set to be rotated out, ever! With my background in Linux administration I was completely baffled as to why this would not be a standard on any server.. Bueller?
So, I went about looking into this and found many solutions. There were two options that stuck out as viable alternatives one was an .adm template and the other was simple bash script... I mean batch script (:
I wanted a quick solution that I could possibly modify for other uses on the fly with minimal fuss, that obviously left out an adm template. So, off to work on a batch script I went. After shaking off the rust of batch scripting, it was an easy solution.
I utilized Sysinternals Psloglist.exe in the below example. A later addition also adds 7zip by Igor Pavlov into the mix so the weeks log files can be zipped and stored for later viewing if necessary.
Below is the code that I used to accomplish this task, please feel free to adjust this code to fit your systems if you are in a similar situation.
