目前我在NLog.Config中有以下配置:
<target name="upd" xsi:type="FilteringWrapper" condition="contains('${message}', 'UPD U40')
or contains('${message}', 'UPD CAX')
or contains('${message}', 'UPD CAY')
or contains('${message}', 'UPD CMVQA')
or contains('${message}', 'UPD U68')
or contains('${message}', 'UPD CBY')
or contains('${message}', 'UPD CBX')
or contains('${message}', 'UPD CUX')
or contains('${message}', 'UPD CELL')
or contains('${message}', 'UPD BPS')
">
<target xsi:type="File" fileName="${basedir}/logs/UPD.log"
layout="${longdate} - ${message}" />
</target>
<target name="other" xsi:type="FilteringWrapper" condition="not contains('${message}', 'UPD U40')
and not contains('${message}', 'UPD CAX')
and not contains('${message}', 'UPD CAY')
and not contains('${message}', 'UPD CMVQA')
and not contains('${message}', 'UPD U68')
and not contains('${message}', 'UPD CBY')
and not contains('${message}', 'UPD CBX')
and not contains('${message}', 'UPD CUX')
and not contains('${message}', 'UPD CELL')
and not contains('${message}', 'UPD BPS')
">
<target xsi:type="File" fileName="${basedir}/logs/${shortdate}.log"
layout="${longdate} - ${message}" />
</target>
...
<logger name="*" minlevel="Debug" writeTo="upd,other"/>
我想要实现的是将所有UPD CAX等模式收集在UPD.log中,其余模式收集在${shortdate} .log中.我做到了.但是,我认为这里存在很大的冗余,因为我必须在两个地方添加模式.
如何简化目标/规则以获得相同的结果?
解决方法:
最简单的简化方法可能是使用变量.您可以将条件置于变量中,然后打开条件是否为真.如果要在一个位置配置它们,文件路径和布局等其他部分也可以是变量.这是一个简单的例子:
<variable name="filterCondition" value="contains('${message}', 'UPD U40')
or contains('${message}', 'UPD CAX')
or contains('${message}', 'UPD CAY')
or contains('${message}', 'UPD CMVQA')
or contains('${message}', 'UPD U68')
or contains('${message}', 'UPD CBY')
or contains('${message}', 'UPD CBX')
or contains('${message}', 'UPD CUX')
or contains('${message}', 'UPD CELL')
or contains('${message}', 'UPD BPS')
"/>
<variable name="logDir" value="${basedir}/logs" />
<variable name="logLayout" value="${longdate} - ${message}" />
<targets>
<target name="upd" xsi:type="FilteringWrapper" condition="${filterCondition}">
<target xsi:type="File" fileName="${logDir}/UPD.log"
layout="${logLayout}" />
</target>
<target name="other" xsi:type="FilteringWrapper" condition="not (${filterCondition})">
<target xsi:type="File" fileName="${logDir}/${shortdate}.log"
layout="${logLayout}" />
</target>
</targets>
