更改log4net配置以每隔x小时创建一个新日志 [英] Change log4net config to create every x hour new log

问题描述

如果我想每隔x个小时记录一次日志，我仍然没有真正知道如何更改log4net.我有这个:

I still dont really get it how to change log4net if I would like to have every x hour a log. I have this:

      <log4net>
        <root>
          <level value="DEBUG"/>
          <appender-ref ref="LogFileAppender"/>
        </root>
        <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
          <param name="File" value="C:\log.txt"/>
          <param name="AppendToFile" value="true"/>
          <rollingStyle value="Size"/>
          <maxSizeRollBackups value="10"/>
          <maximumFileSize value="100MB"/>
          <staticLogFileName value="true"/>
          <layout type="log4net.Layout.PatternLayout">
            <param name="ConversionPattern" value="%-5p%d{yyyy-MM-dd hh:mm:ss} – %m%n"/>
          </layout>
        </appender>
  </log4net>

我有一个日志，我总是在该log.txt中添加日志-现在，我想让我们每天说一个新的日志文件(24小时)，或者说每12小时说一个新日志.我必须在配置中进行哪些更改?对我的配置有什么建议吗?谢谢

I have one log and Im adding the logs always in this one log.txt - now I would like to have lets say for every day a new log file (24hours) or maybe for every 12hours a new log. What do I have to change in my config? Any suggestions to my config? Thank you

此示例显示如何配置RollingFileAppender以在某个日期周期内滚动日志文件.此示例将每分钟滚动一次日志文件！要更改滚动周期，请调整DatePattern值.例如，日期模式"yyyyMMdd"将每天滚动.有关可用模式的列表，请参见System.Globalization.DateTimeFormatInfo.

This example shows how to configure the RollingFileAppender to roll log files on a date period. This example will roll the log file every minute! To change the rolling period adjust the DatePattern value. For example, a date pattern of "yyyyMMdd" will roll every day. See System.Globalization.DateTimeFormatInfo for a list of available patterns.

<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="logfile" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<datePattern value="yyyyMMdd-HHmm" />
<layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>

在您的特定情况下，上面带有<datePattern value="yyyyMMdd-HH" />的示例仅允许您每小时记录一次.

In your particular case, the above example with <datePattern value="yyyyMMdd-HH" /> would only allow you to log every hour.

但是，如果要每隔X小时记录一次，则可以创建一个从RollingFileAppender派生的自定义附加程序，并覆盖AdjustFileBeforeAppend方法，该方法将根据下一个计划的日志间隔日期检查当前时间.例如，请参见将Log4Net RollingFileAppender设置为每周滚动.

However, if you wanted to log every X hour, you could create a custom appender derived from RollingFileAppender and override the AdjustFileBeforeAppend method that would check the current time against your next scheduled log interval date. See Have a Log4Net RollingFileAppender set to roll weekly for example.
