如何在log4j2中配置StatisticsCsvLayout

Question

Need help from migrating log4j to log4j2. I have a rollingFileAppender. I need this appender to make use of "StatisticsCsvLayout" in org.perf4j. Previously in log4j 1.x version we used to directly refer the StatisticsCsvLayout from any appender using following tag in log4j.xml.

<Layout class='org.perf4j.log4j.StatisticsCsvLayout'/>

We are unable to confire this from log4j2.xml as we are not able to make use of external layouts directly. Please tell me how to configure this in log4j2.xml.

Answer 1

If the org.perf4j StatisticsCsvLayout is not directly compatible with log4j2, you may need to create your own (or convince the perf4j people to port this layout to log4j2). Fortunately creating a custom layout is not very difficult. Here is some sample code. You can also look at the log4j2 source code for more details, like how to pass parameters.
