c# - 在应用程序和设置日志下的子目录中创建事件日志

Question

我一直在寻找一种方法来在 Applications and Services Logs 的子目录下创建多个单独的事件日志。 , 以同样的方式有一个子目录 Microsoft然后它有一个子目录Windows然后使用应用程序登录的各种其他目录。

应用程序和服务\Microsoft\Windows\All-User-Install-Agents

应用程序和服务\Microsoft\Windows\AppHost

...

我想创建如下内容

应用程序和服务\我的公司\应用程序 1

应用程序和服务\我的公司\应用程序 2

应用程序和服务\我的公司\应用程序 3

我遇到的所有样本都只允许你直接在 Applications and Services下创建日志目录而不是创建子目录。
谢谢

Answer 1

如果仍然需要，我为我找到了一个很好的工作解决方案，尽管它使用的是 Powershell 而不是 C#。
你需要2个步骤:

创建日志本身

创建(如果需要)事件源

这是我用于创建位于 Custom EventLog 的子文件夹的代码:

function New-WindowsCustomLog
{
    <#
    .SYNOPSIS
        Create a custom Eventlog

    .DESCRIPTION
        This function will create a new eventlog located under 'Application and Serviceprotocolls' using a company subfolder and if needed additional functional subfolder.

    .PARAMETER PrimaryKey
        Mostly used for the company name.

    .PARAMETER ApplicationName
        Application name.

    .PARAMETER ApplicationFunction
        Optional: If you need to create another subfolder for functions.

    .PARAMETER LogName
        The name of the Log itself.

    .PARAMETER ProviderGUID
        Provider/Publisher GUID, if you don't have one, create by using New-GUID enter without {} around.

    .EXAMPLE
                New-WindowsCustomLog -PrimaryKey 'My Company' -ApplicationName 'My Cool Tool' -LogName 'Operational' -ProviderGUID '{49ab7419-7113-40d1-8910-8be1c3f96d21}'

    .EXAMPLE
                New-WindowsCustomLog -PrimaryKey 'My Company' -ApplicationName 'My Cool Tool' -ApplicationFunction 'Incoming' -LogName 'Requests' -ProviderGUID '{49ab7419-7113-40d1-8910-8be1c3f96d21}'
                New-WindowsCustomLog -PrimaryKey 'My Company' -ApplicationName 'My Cool Tool' -ApplicationFunction 'Outgoing' -LogName 'Requests' -ProviderGUID '{49ab7419-7113-40d1-8910-8be1c3f96d21}'

    param
    (
        [Parameter(Mandatory = $true,
                   Position = 0)]
        [string]$PrimaryKey,
        [Parameter(Mandatory = $true,
                   Position = 1)]
        [string]$ApplicationName,
        [Parameter(Position = 2)]
        [string]$ApplicationFunction,
        [Parameter(Mandatory = $true,
                   Position = 3)]
        [string]$LogName,
        [Parameter(Mandatory = $true,
                   Position = 4)]
        [String]$ProviderGUID
    )
    $publisherGuid = "{$($ProviderGUID)}"
    $primaryLocation = 'HKLM:\Software\Microsoft\Windows\CurrentVersion\WINEVT\Channels'
    $secondaryLocation = 'HKLM:\SYSTEM\CurrentControlSet\Services\EventLog\Application'
    #$thirdLocation = 'HKLM:\SYSTEM\CurrentControlSet\Services\EventLog\System' # needed for driver purposes
    $publisher = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\WINEVT\Publishers'

    if (-not ([string]::IsNullOrEmpty($ApplicationFunction)))
    {
        $primaryLogName = $PrimaryKey + '-' + $ApplicationName + '-' + $ApplicationFunction + '§' + $LogName
        $secondaryLogName = $PrimaryKey + '-' + $ApplicationName + '-' + $ApplicationFunction
    }
    else
    {
        $primaryLogName = $PrimaryKey + '-' + $ApplicationName + '-' + '§' + $LogName
        $primaryLogNameSlash = $primaryLogName.Replace("§", "/")
        $secondaryLogName = $PrimaryKey + '-' + $ApplicationName
    }
    $evtxFilePath = "%SystemRoot%\System32\Winevt\Logs\$($secondaryLogName)%4$($LogName).evtx"
    $primaryEventRoot = Join-Path -Path $primaryLocation -ChildPath $primaryLogName
    $secondaryEventRoot = Join-Path -Path $secondaryLocation -ChildPath $secondaryLogName
    #$thirdEventRoot = Join-Path -Path $thirdLocation -ChildPath $secondaryLogName # needed for driver purposes
    $publisherEventRoot = Join-Path -Path $publisher -ChildPath $publisherGuid
    if (-not (Test-Path $primaryLogNameSlash)) #$primaryEventRoot.Replace("§", "/")))
    {
        &reg add $primaryLogNameSlash.Replace(":", "") # used because I wasn't able to write a real / to registry key name by CMDLET
        New-ItemProperty -Path $primaryLogNameSlash -Name 'Enabled' -PropertyType DWord -Value 1
        New-ItemProperty -Path $primaryLogNameSlash -Name 'Type' -PropertyType DWord -Value 1
        New-ItemProperty -Path $primaryLogNameSlash -Name 'Isolation' -PropertyType DWord -Value 0
        New-ItemProperty -Path $primaryLogNameSlash -Name 'RestrictGuestAccess' -PropertyType String -Value "1"
        New-ItemProperty -Path $primaryLogNameSlash -Name 'OwningPublisher' -PropertyType String -Value $publisherGuid
    }
    if (-not (Test-Path $secondaryEventRoot))
    {
        New-Item -Path $secondaryEventRoot
        New-ItemProperty -Path $secondaryEventRoot -Name 'ProviderGuid' -PropertyType String -Value $publisherGuid
        New-ItemProperty -Path $secondaryEventRoot -Name 'File' -PropertyType ExpandString -Value $evtxFilePath
    }
    <# needed for driver purposes
    if (-not (Test-Path $thirdEventRoot))
    {
        New-Item -Path $thirdEventRoot
        New-ItemProperty -Path $thirdEventRoot -Name 'ProviderGuid' -PropertyType String -Value $publisherGuid
        #New-ItemProperty -Path $thirdEventRoot -Name 'EventMessageFile' -PropertyType ExpandString -Value $evtMessageFile
    }
    #>
    if (-not (Test-Path $publisherEventRoot))
    {
        New-Item -Path $publisherEventRoot -Value $secondaryLogName
        New-ItemProperty -Path $publisherEventRoot -Name 'Enabled' -PropertyType DWord -Value 1
        $channelReference = Join-Path -Path $publisherEventRoot -ChildPath "ChannelReference"
        New-Item -Path $channelReference
        New-ItemProperty -Path $channelReference -Name 'Count' -PropertyType DWord -Value 1
        $reference0 = Join-Path -Path $channelReference -ChildPath "0"
        New-Item -Path $reference0 -Value $primaryLogName.Replace("§", "/")
        New-ItemProperty -Path $reference0 -Name 'Flags' -PropertyType DWord -Value 0
        New-ItemProperty -Path $reference0 -Name 'Id' -PropertyType DWord -Value 16
    }
    return $primaryLogNameSlash
}

接下来是创建事件源的简单函数(如果日志可用且源尚未注册):

function New-WindowsEventSource
{
    [CmdletBinding()]
    param
    (
        [Parameter(Mandatory = $true,
                   Position = 0)]
        [ValidateScript({ [System.Diagnostics.EventLog]::Exists($_) })]
        [string]$EventLogName,
        [Parameter(Mandatory = $true,
                   Position = 1)]
        [ValidateScript({ (-not ([System.Diagnostics.EventLog]::SourceExists($_))) })]
        [string]$EventSourceName
    )
    [System.Diagnostics.EventLog]::CreateEventSource($EventSourceName, $EventLogName)
}

这是创建源/填充 EventLog 的方法:

New-WindowsEventSource -EventLogName "My Company-My Cool Tool-Incoming/Requests" -EventSourceName "webbrowser"

Write-EventLog -LogName "My Company-My Cool Tool-Incoming/Requests" -Source "webbrowser" -EntryType Information -EventId 100 -Message "New request received."
