Sorting Windows events by UserID: Part II (Building a Module)

I am a bit late to some v2.0 functionality.  I made my first attempt at creating a module, in this case a six function script that queries general information from an event log. I ran into at least two problems:

• (a) get-winevent is slow for high volume queries
• (b) modules so encapsulate their variables in functions that I could not find how to call all functions globally from an internal or external script.                                                                                                                                                                                                                                                                                                                                                                                           

Sorting Windows events by UserID

Sorting Windows events by UserID is a critical piece of auditing. In the code and examples below, I concentrate on:


$Logs="System","Application","Microsoft-Windows-GroupPolicy/Operational"


purposefully leaving out the Security log. We can create a simple function that allows us to check all events logs on any machine sorted by file size:

function CheckEventLogsBySize
{
get-winevent -listlog * | Sort -desc FileSize |
ft -auto LogName,@{Label="FileLogSize(MB)"; Expression={$_.FileSize/1MB}},@{Label="MaxLogSize(MB)"; Expression={$_.MaximumSizeINBytes/1MB}},LastWriteTime,IsLogFull 
}
