按日期分类的事件日志

Question

我正在尝试从特定日期捕获日志文件，但无论返回多少天我都没有得到任何结果。

Get-EventLog -LogName Application -EntryType Warning -Source MicrosoftDynamicsNAVClientWebClient | Select Message -ExpandProperty Message | Where { ($_.Message -match 'Shutdown') -and ($_.TimeGenerated -gt [datetime]::Today.AddDays('-1')) }

这是日志文件列表

Answer 1

您的问题是您使用 Select cmdlet 来扩展 Message。因此，当您尝试过滤 TimeGenerated 时，属性不存在。如果您只想要消息，则过滤后 select。

Get-EventLog -LogName Application -EntryType Warning -Source MicrosoftDynamicsNAVClientWebClient | Where { ($_.Message -match 'Shutdown') -and ($_.TimeGenerated -gt [datetime]::Today.AddDays(-1)) } | Select -ExpandProperty Message
