Java – use log4j to customize the log file name in mule

I'm trying to modify log4j XML to use the appropriate appender to change the log file name generated by mule

This is log4j A fragment of XML

<RollingFile name="Rolling-Async-Perf" fileName="/usr/local/mule/logs/${app_name}.log"
            filePattern="./logs/${date:yyyy-MM}/perf-%d{yyyy-MM-dd}-%i.log.gz"  immediateFlush="false">

Here's what I'm loading with log4j Set application in the class of XML related properties_ Method for the value of name

System.setProperty("app_name","AppName");

However, the generated file name is ${app_name} Log instead of appName log.

Any ideas on how to get file names based on custom attributes in mule?

Solution

There are two options:

1) In mule_ HOME / conf / wrapper. Add an attribute to the conf file, for example:

wrapper.java.additional.15=-Dapp_name=AppName

Or 2) in log4j2 In the configuration element of the XML file example here:

<Properties>
  <Property name="app_name">AppName</Property>
</Properties>
