Log4Net配置 - LevelMatchFilter [英] Log4Net configuration - LevelMatchFilter

问题描述

由于log4net中存在以下级别：
$ b

• 所有


• DEBUG
$

• 警告


• 错误


• 致命


• 关闭

任何人都可以在log4net中告诉我如何只记录 INFO& ERROR 或 DEBUG&错误？我的意思是能够记录两个不同的级别，这是不是按顺序？

我不能这样做，如果我使用以下，因为警告信息也将被记录我不想要：

 < filter type =log4net.Filter.LevelRangeFilter> 
< acceptOnMatch value =true/> 
< levelMin value =INFO/> 
< levelMax value =ERROR/> 
< / filter> 
  

解决方案

使用LevelMatchFilter与DenyAllFilter结合：

< filter type =log4net.Filter.LevelMatchFilter>
< acceptOnMatch value =true/>
< levelToMatch value =INFO/>
< / filter>
< filter type =log4net.Filter.LevelMatchFilter>
< acceptOnMatch value =true/>
< levelToMatch value =ERROR/>
< / filter>
< filter type =log4net.Filter.DenyAllFilter/>


As there are following levels in log4net

• ALL
• DEBUG
• INFO
• WARN
• ERROR
• FATAL
• OFF

Can anyone please tell me in log4net how can I log only INFO & ERROR or DEBUG & ERROR? What I mean here is be able to log two different levels which are not in sequence?

I can't do if I use following because warning messages will be logged as well which I don't want:

<filter type="log4net.Filter.LevelRangeFilter">
    <acceptOnMatch value="true" />
    <levelMin value="INFO" />
    <levelMax value="ERROR" />
</filter>

解决方案

Use LevelMatchFilter in conjunction with DenyAllFilter:

<filter type="log4net.Filter.LevelMatchFilter">
  <acceptOnMatch value="true" />
  <levelToMatch  value="INFO" />
</filter>
<filter type="log4net.Filter.LevelMatchFilter">
  <acceptOnMatch value="true" />
  <levelToMatch  value="ERROR" />
</filter>
<filter type="log4net.Filter.DenyAllFilter" />
