The Big Picture (Powershell log-spanning event script)
4/23/2018: This is a quick 1-liner script aimed at pulling all eventlog events over a specific time span, across multiple logs. Gives you the 'high-view' timeline of the sequence of events, when you're trying to correlate that odd issue to a root cause.
Sure you can check each constituent log - System, Application, and a Crimson/App-log one by one, and mentally compare the time sequence across the logs.
But the handy bit to this chunk of code is that it quickly & neatly pulls all of the events together into one csv, sorted into time sequence, ready for quick review: Pop the Csv open, and you can directly see the events that occurred just ahead of your app's issues - possibly spot the OS/System-level item that actually was the actual root of the problem. :)
Usage:
Note: The underlying Get-WinEvent cmdlet requires Powershell v2+.
Set the $tlogs variable to an array of the logs you want collected (System, Application & 'Lync Server' log in the example).
Set the $fltEvt hash's StartTime & EndTime to the time interval you want to examine (e.g. just before your app symptom appeared, and just after it ended).
If you want to run the command remotely (rather than collecting logs from the local box), update $tSrvr to specify the name of the remote server you want checked.
The script will aggregqate the spec'd log events together, sort them on 'TimeCreated', and output them to a csv file with the name pattern:
