The Orion platform produces a *LOT* of logs. Like an absolute crap-ton of them. Sometimes you want to dig through them to find a string, but you don't want to have to scroll through and manually open each log file.
PowerShell to the rescue!
Get-ChildItem -Path c:\programdata\solarwinds\logs\* -include *.log -recurse | ? {$_.LastWriteTime -gt (Get-Date).AddDays(-1)} | Select-String -pattern "appzone"
This command will grab the list of files from the last 1 day and then return all of the lines with the value "appzone"
Hopefully this little tidbit helps you dig through your logs. May I recommend searching for [ERROR] on a regular basis?
