Log4net does not roll the log file sometimes when the calendar set is installed today

Question

I have a C # Windows application that uses log4net for logging. Here's how the registrars are configured:

 <log4net>
    <appender name="DebugFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="Local\logs\ApplnTrace.log" />
      <threshold value="INFO" />
      <appendToFile value="true" />
      <rollingStyle value="Date" />
      <datePattern value="yyyyMMdd" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%d [%5p] - (%file:%line) %m%n" />
      </layout>
    </appender>
    <appender name="MSGFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value=".\local\logs\MsgTrace.log" />
      <threshold value="INFO" />
      <appendToFile value="true" />
      <rollingStyle value="Date" />
      <datePattern value="yyyyMMdd" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%d %n%m%n" />
      </layout>
    </appender>
    <logger name="ApplnLogger">
      <appender-ref ref="DebugFileAppender" />
    </logger>
    <logger name="MsgLogger">
      <appender-ref ref="MSGFileAppender" />
    </logger>
 </log4net>

Files are rolled based on the date sometimes and sometimes not, and when the files are not upside down, the log also stops. Can someone help me figure out why?

Answer 1

log4Net is for a quiet exit. When something stops working, a problem usually arises (most often it is a configuration problem or a file system problem).

You might want to try enabling log4net internal debugging. Park this key in <appSettings>your app.config element :

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="log4net.Internal.Debug" value="true"/>
  </appSettings>
</configuration>

. Log4net . System.Console System.Diagnostics.Trace. app.config. , , , :

<configuration>
...
  <system.diagnostics>
    <trace autoflush="true">
      <listeners>
        <add
          name="textWriterTraceListener" 
          type="System.Diagnostics.TextWriterTraceListener" 
          initializeData="C:\tmp\log4net.txt"
          />
      </listeners>
    </trace>
  </system.diagnostics>
...
</configuration>
