MSSQL/WMI/PowerShell结合篇（二）创建WMI监控

文中所介绍的监控类型的WMI消费者主要为CommandLineEventConsumer、LogFileEventConsumer

详细介绍参阅以下链接：

CommandLineEventConsumer

LogFileEventConsumer

下面以PowerShell脚本为例，介绍如何创建WMI事件监控

一、LogFileEventConsumer示例

1、创建EventFilter，对需要监控的事件进行过滤

${EventNamespace} = "the event namespace which is to be monitored"

${QueryLanguage} = 'WQL'

${Namespace}="root\subscription"

${ComputerName}="."

${Query}= "WQL Query Statement";

${Name}="EventFilter Name"

${NewFilter} = ([wmiclass]"\\${ComputerName}\${Namespace}:__EventFilter").CreateInstance()

${NewFilter}.{QueryLanguage} = ${QueryLanguage}

${NewFilter}.{Query} = ${Query}

${NewFilter}.{EventNamespace} = ${EventNamespace}

${NewFilter}.{Name} = ${Name}

$result = $NewFilter.Put()

2、创建Consumer，触发相应的动作

${Text} ='the text which is to be logged'

${FileName}="FileName"

${IsUnicode}="true"

${ComputerName}="."

${Name}="EventConsumer Name";

${NewConsumer} = ([wmiclass]"\\${ComputerName}\root\subscription:LogFileEventConsumer").CreateInstance()

${NewConsumer}.{Name} = ${Name}

${NewConsumer}.{FileName} = ${FileName}

${NewConsumer}.{IsUnicode} = ${IsUnicode}

${NewConsumer}.{Text} = ${Text}

$NewConsumer.Put()

3、创建Binding，绑定EventFilter、Cousumer，使得事件被捕获时立即触发动作

${Namespace}="root\subscription"

${ComputerName}="."

${NewBinding} = ([wmiclass]"\\${ComputerName}\${Namespace}:__FilterToConsumerBinding").CreateInstance()

${NewBinding}.Filter = "\\${ComputerName}\ROOT\Subscription:__EventFilter.Name=`"EventFilter Name`""

${NewBinding}.{Consumer} ="\\${ComputerName}\ROOT\Subscription:LogFileEventConsumer.Name=`"EventConsumer Name`""

${NewBinding}.{MaintainSecurityContext} = ${FALSE}

${NewBinding}.{SlowDownProviders} = ${FALSE}

$NewBinding.Put()

二、CommandLineEventConsumer示例

1、创建EventFilter，对需要监控的事件进行过滤

${EventNamespace} = "the event namespace which is to be monitored"

${QueryLanguage} = 'WQL'

${Namespace}="root\subscription"

${ComputerName}="."

${Query}= "WQL Query Statement";

${Name}="EventFilter Name"

${NewFilter} = ([wmiclass]"\\${ComputerName}\${Namespace}:__EventFilter").CreateInstance()

${NewFilter}.{QueryLanguage} = ${QueryLanguage}

${NewFilter}.{Query} = ${Query}

${NewFilter}.{EventNamespace} = ${EventNamespace}

${NewFilter}.{Name} = ${Name}

$result = $NewFilter.Put()

2、创建Consumer，触发相应的动作(以执行PowerShell命令行为例)

${Namespace}="root\subscription"

${ComputerName}="."

${Name}="EventConsumer Name";

$ExecutablePath="c:\xxx\xxx\powershell.exe"

$CommandLineTemplate="powershell.exe -File D:\xxx\xxx.ps1"

${NewConsumer} = ([wmiclass]"\\${ComputerName}\${Namespace}:CommandLineEventConsumer").CreateInstance()

${NewConsumer}.{CommandLineTemplate} = ${CommandLineTemplate}

${NewConsumer}.{ExecutablePath} = ${ExecutablePath}

${NewConsumer}.{name}=${Name}

$NewConsumer.Put()

3、创建Binding，绑定EventFilter、Cousumer，使得事件被捕获时立即触发动作

${Namespace}="root\subscription"

${ComputerName}="."

${NewBinding} = ([wmiclass]"\\${ComputerName}\${Namespace}:__FilterToConsumerBinding").CreateInstance()

${NewBinding}.Filter = "\\${ComputerName}\ROOT\Subscription:__EventFilter.Name=`"EventFilter Name`""

${NewBinding}.{Consumer} ="\\${ComputerName}\ROOT\Subscription:CommandLineEventConsumer.Name=`"EventConsumer Name`""

${NewBinding}.{MaintainSecurityContext} = ${FALSE}

${NewBinding}.{SlowDownProviders} = ${FALSE}

$NewBinding.Put()
