我需要使用 log4net 登录到多个目标(loggly、控制台、文件)。对于 loggly,我需要登录 JSON 以获取一些元数据以查找日志。我通过将元数据添加到像这样的动态消息对象(示例主题)来为此更改消息对象。
public void Info(string message)
{
log.Info(GetLogObject(message));
}
private object GetLogObject(string message, Exception ex = null)
{
dynamic obj = new ExpandoObject();
obj.message = message;
obj.exception = ex;
obj.subject = _configuration.SubjectId;
return obj;
}
应用程序配置
<log4net>
<root>
<level value="ALL" />
<appender-ref ref="ConsoleAppender" />
<appender-ref ref="RollingFileAppender" />
<appender-ref ref="LogglyAppender" />
</root>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date - %message%newline" />
</layout>
</appender>
<appender name="LogglyAppender" type="log4net.loggly.LogglyAppender, log4net-loggly">
<rootUrl value="https://logs-01.loggly.com/" />
<inputKey value="*" />
<tag value="AppTag" />
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="ERROR" />
<levelMax value="FATAL" />
</filter>
</appender>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="Logs/rolling.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %level - %message%newline" />
</layout>
</appender>
现在控制台和 FileAppender 正在记录 JSON,如下所示:
2017-06-12 15:28:10,236 INFO - {[message, Will collect every 1 Hours, 0 Minutes and 0 Seconds], [exception, ], [subject, 11111111-1111-1111-1111-111111111111]}
2017-06-12 15:28:10,271 INFO - {[message, Collection Round started at 12.06.2017 13:28:10], [exception, ], [subject, 11111111-1111-1111-1111-111111111111]}
我希望这些附加程序仅记录消息本身(obj.message),如下所示:
2017-06-12 15:28:10,236 INFO - Will collect every 1 Hours, 0 Minutes and 0 Seconds
2017-06-12 15:28:10,271 INFO - Collection Round started at 12.06.2017 11:17:29
我怎样才能做到这一点?非常感谢 :)
