是否有方法指定目标日志文件，以便microsoft monitoring agent监听并从代码中提取日志？

Question

我正在考虑使用Microsoft monitoring agent从系统上的日志文件中收集一些日志记录，并将它们发送到日志分析工作区。是否有一种方法指定目标文件（自定义日志文件），代理将监听并将日志直接流式传输到azure工作区。我知道可以通过azure portal在工作区中添加一个额外的数据源（由此链接https://docs.microsoft.com/en-us/azure/azure-monitor/platform/data-sources-custom-logs指定）来实现。我正在寻找一种从C#代码/PowerShell脚本配置这些数据源的方法。（可能是我不知道的api或sdk）。

若要添加自定义日志，请使用New-AzOperationalInsightScustomLogDataSource。

下面是其他powershell命令，它们可以方便地查询和创建LogAnalytics数据源。

get-azoperationalinsightsdatasource
New-AzOperationalInsightsApplicationInsightsDataSource 
New-AzOperationalInsightsAzureActivityLogDataSource
New-AzOperationalInsightsComputerGroup
New-AzOperationalInsightsCustomLogDataSource
New-AzOperationalInsightsLinuxPerformanceObjectDataSource
New-AzOperationalInsightsLinuxSyslogDataSource
New-AzOperationalInsightsSavedSearch
New-AzOperationalInsightsStorageInsight
New-AzOperationalInsightsWindowsEventDataSource
New-AzOperationalInsightsWindowsPerformanceCounterDataSource

• ARM模板

对于自定义日志的Arm模板格式如下所示。请参阅详细链接https://docs.microsoft.com/en-us/azure/azure-monitor/platform/template-workspace-configuration
