是的。我们正在生产中这样做。我们有一个 PowerShell 脚本...（是的，在 Windows 上运行...）

[datetime]$killDate = $(Get-Date).AddDays(-1)
[string]$dbPath = $(Get-Content "C:\Program Files\MongoDB\Server\3.2\bin\Primary_Dev.cfg" | sls dbPath:)
[string]$dbPathNoWhitespace = $dbPath.Trim(' ')
[string]$dbPathValue = $dbPathNoWhitespace.Split(' ')[1]
if (-not Test-Path $dbPathValue) { throw "finding logs path didn't work in kill-MongoWiredTigerLogsWithFire.ps1" }

cd $dbPathValue

$(gci WiredTigerStat* | where LastWriteTime -lt $killDate).FullName | % {
  rm $_ -force
}
