Config file setting for Multi appenders(file and app insight) with different log level

问题

我有记录到文件和应用洞察的不同日志级别的要求。我有以下配置文件设置，它在文件和应用洞察中都以DEBUG级别记录日志。

  1. <?xml version="1.0" encoding="utf-8" ?>
  2. <configuration>
  3.   <configSections>
  4.     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  5.   </configSections>
  6.   <log4net>
  7.     <root>
  8.       <level value="DEBUG"/>
  9.       <appender-ref ref="ConsoleAppender"/>
  10.     </root>
  11.     <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
  12.       <level value="DEBUG" />
  13.       <layout type="log4net.Layout.PatternLayout">
  14.         <conversionPattern value="%utcdate [%thread] %-5level %logger - %message%newline" />
  15.       </layout>
  16.     </appender>
  17.     <appender name="ApplicationInsightAppender" type="Microsoft.ApplicationInsights.Log4NetAppender.ApplicationInsightsAppender, Microsoft.ApplicationInsights.Log4NetAppender">
  18.       <level value="ERROR" />
  19.       <layout type="log4net.Layout.PatternLayout">
  20.         <conversionPattern value="%utcdate [%thread] %-5level %logger - %message%newline"/>
  21.       </layout>       
  22.     </appender>
  23.     <logger name ="appinsightlogger">
  24.       <level value ="ERROR"></level>
  25.       <appender-ref ref="ApplicationInsightAppender"/>
  26.     </logger>
  27.   </log4net>
  28. </configuration>

我还尝试将这两个附加程序注册到根元素下，如下所示：

  1. <root>
  2.   <level value="DEBUG"/>
  3.   <appender-ref ref="ConsoleAppender"/>
  4.   <level value="ERROR"></level>
  5.   <appender-ref ref="ApplicationInsightAppender"/>
  6. </root>

但仍然没有看到所需的结果。有人可以帮助吗？

I have requirement to log to file as well as app insight with different log levels. I have below config file setting which logs with DEBUG level in both file as well as app insight.

  1. &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot; ?&gt;
  2. &lt;configuration&gt;
  3.   &lt;configSections&gt;
  4.     &lt;section name=&quot;log4net&quot; type=&quot;log4net.Config.Log4NetConfigurationSectionHandler, log4net&quot; /&gt;
  5.   &lt;/configSections&gt;
  6.   &lt;log4net&gt;
  7.     &lt;root&gt;
  8.       &lt;level value=&quot;DEBUG&quot;/&gt;
  9.       &lt;appender-ref ref=&quot;ConsoleAppender&quot;/&gt;
  10.     &lt;/root&gt;
  11.     &lt;appender name=&quot;ConsoleAppender&quot; type=&quot;log4net.Appender.ConsoleAppender&quot;&gt;
  12.       &lt;level value=&quot;DEBUG&quot; /&gt;
  13.       &lt;layout type=&quot;log4net.Layout.PatternLayout&quot;&gt;
  14.         &lt;conversionPattern value=&quot;%utcdate [%thread] %-5level %logger - %message%newline&quot; /&gt;
  15.       &lt;/layout&gt;
  16.     &lt;/appender&gt;
  17.     &lt;appender name=&quot;ApplicationInsightAppender&quot; type=&quot;Microsoft.ApplicationInsights.Log4NetAppender.ApplicationInsightsAppender, Microsoft.ApplicationInsights.Log4NetAppender&quot;&gt;
  18.       &lt;level value=&quot;ERROR&quot; /&gt;
  19.       &lt;layout type=&quot;log4net.Layout.PatternLayout&quot;&gt;
  20.         &lt;conversionPattern value=&quot;%utcdate [%thread] %-5level %logger - %message%newline&quot;/&gt;
  21.       &lt;/layout&gt;       
  22.     &lt;/appender&gt;
  23.     &lt;logger name =&quot;appinsightlogger&quot;&gt;
  24.       &lt;level value =&quot;ERROR&quot;&gt;&lt;/level&gt;
  25.       &lt;appender-ref ref=&quot;ApplicationInsightAppender&quot;/&gt;
  26.     &lt;/logger&gt;
  27.   &lt;/log4net&gt;
  28. &lt;/configuration&gt;

I also tried registering both the appenders under root element like below

  1. &lt;root&gt;
  2.   &lt;level value=&quot;DEBUG&quot;/&gt;
  3.   &lt;appender-ref ref=&quot;ConsoleAppender&quot;/&gt;
  4.   &lt;level value =&quot;ERROR&quot;&gt;&lt;/level&gt;
  5.   &lt;appender-ref ref=&quot;ApplicationInsightAppender&quot;/&gt;
  6. &lt;/root&gt;

But still did not see required results. Can anyone help on this?

得分: 1

一个appender没有level属性。
Log4net通过下面的消息通知了这一点。

log4net:ERROR XmlHierarchyConfigurator: 无法找到属性[level]以设置[log4net.Appender.ConsoleAppender]上的对象

要使一个appender以不同的级别记录日志，请使用filter。

下面的示例显示了如何配置ApplicationInsightAppender仅记录错误及更高级别的日志。

  1. <appender name="ApplicationInsightAppender" type="Microsoft.ApplicationInsights.Log4NetAppender.ApplicationInsightsAppender, Microsoft.ApplicationInsights.Log4NetAppender">
  2.   <filter type="log4net.Filter.LevelRangeFilter">
  3.     <levelMin value="ERROR" />
  4.     <levelMax value="FATAL" />
  5.   </filter>
  6.   <layout type="log4net.Layout.PatternLayout">
  7.     <conversionPattern value="%utcdate [%thread] %-5level %logger - %message%newline"/>
  8.   </layout>       
  9. </appender>

完整示例，使ConsoleAppender记录所有消息，而ApplicationInsightAppender只从错误级别开始记录。

  1. <log4net>
  2.   <root>
  3.     <level value="DEBUG"/>
  4.     <appender-ref ref="ConsoleAppender" />
  5.     <appender-ref ref="ApplicationInsightAppender" />
  6.   </root>
  8.   <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
  9.     <layout type="log4net.Layout.PatternLayout">
  10.       <conversionPattern value="%utcdate [%thread] %-5level %logger - %message%newline" />
  11.     </layout>
  12.   </appender>
  14.   <appender name="ApplicationInsightAppender" type="Microsoft.ApplicationInsights.Log4NetAppender.ApplicationInsightsAppender, Microsoft.ApplicationInsights.Log4NetAppender">
  15.     <filter type="log4net.Filter.LevelRangeFilter">
  16.       <levelMin value="ERROR" />
  17.       <levelMax value="FATAL" />
  18.     </filter>
  19.     <layout type="log4net.Layout.PatternLayout">
  20.       <conversionPattern value="%utcdate [%thread] %-5level %logger - %message%newline"/>
  21.     </layout>       
  22.   </appender>
  23. </log4net>

请注意，这些是XML配置文件的示例，用于配置Log4net日志记录器。

英文:

An appender doesn't have a level property.
Log4net notifies about this with below message.

> log4net:ERROR XmlHierarchyConfigurator: Cannot find Property [level] to set object on [log4net.Appender.ConsoleAppender]

To have an appender log with a different level, use a filter.

Below example shows how to configure the ApplicationInsightAppender to only log errors and upwards.

  1. &lt;appender name=&quot;ApplicationInsightAppender&quot; type=&quot;Microsoft.ApplicationInsights.Log4NetAppender.ApplicationInsightsAppender, Microsoft.ApplicationInsights.Log4NetAppender&quot;&gt;
  2.   &lt;filter type=&quot;log4net.Filter.LevelRangeFilter&quot;&gt;
  3.     &lt;levelMin value=&quot;ERROR&quot; /&gt;
  4.     &lt;levelMax value=&quot;FATAL&quot; /&gt;
  5.   &lt;/filter&gt;
  6.   &lt;layout type=&quot;log4net.Layout.PatternLayout&quot;&gt;
  7.     &lt;conversionPattern value=&quot;%utcdate [%thread] %-5level %logger - %message%newline&quot;/&gt;
  8.   &lt;/layout&gt;       
  9. &lt;/appender&gt;

Full example, having the ConsoleAppender log all messages and the ApplicationInsightAppender only starting from error.

  1. &lt;log4net&gt;
  2.   &lt;root&gt;
  3.     &lt;level value=&quot;DEBUG&quot;/&gt;
  4.     &lt;appender-ref ref=&quot;ConsoleAppender&quot; /&gt;
  5.     &lt;appender-ref ref=&quot;ApplicationInsightAppender&quot; /&gt;
  6.   &lt;/root&gt;
  8.   &lt;appender name=&quot;ConsoleAppender&quot; type=&quot;log4net.Appender.ConsoleAppender&quot;&gt;
  9.     &lt;layout type=&quot;log4net.Layout.PatternLayout&quot;&gt;
  10.       &lt;conversionPattern value=&quot;%utcdate [%thread] %-5level %logger - %message%newline&quot; /&gt;
  11.     &lt;/layout&gt;
  12.   &lt;/appender&gt;
  14.   &lt;appender name=&quot;ApplicationInsightAppender&quot; type=&quot;Microsoft.ApplicationInsights.Log4NetAppender.ApplicationInsightsAppender, Microsoft.ApplicationInsights.Log4NetAppender&quot;&gt;
  15.     &lt;filter type=&quot;log4net.Filter.LevelRangeFilter&quot;&gt;
  16.       &lt;levelMin value=&quot;ERROR&quot; /&gt;
  17.       &lt;levelMax value=&quot;FATAL&quot; /&gt;
  18.     &lt;/filter&gt;
  19.     &lt;layout type=&quot;log4net.Layout.PatternLayout&quot;&gt;
  20.       &lt;conversionPattern value=&quot;%utcdate [%thread] %-5level %logger - %message%newline&quot;/&gt;
  21.     &lt;/layout&gt;       
  22.   &lt;/appender&gt;
  23. &lt;/log4net&gt;
  24.
