Hourly log4net RollingFileAppender

问题

Is it possible to configure log4net to roll files each hour? If not - any hints on how to override RollingFileAppender with required functionality to make HourlyRollingFileAppender?

回答1:

Yes: set the datePattern element's value to "yyyyMMdd-HH"

<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
  <file value="logfile" />
  <appendToFile value="true" />
  <rollingStyle value="Date" />

  <datePattern value="yyyyMMdd-HH" />

  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
  </layout>
</appender>
