To create a custom log configuration in AEM, the developer should create an OSGi configuration file for the org.apache.sling.commons.log.LogManager.factory.writer component. This configuration file should be placed under the appropriate runmode-specific folder within the config directory.
Here is the detailed process:
* Create Configuration File:
* Create a new XML file named
org.apache.sling.commons.log.LogManager.factory.writer-<identifier>.xml in the config.<runmode> folder.
* The <identifier> can be any unique identifier for your custom log configuration.
* Specify Configuration:
* Add the necessary configuration properties within this XML file. For example:
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root
xmlns:sling="http://sling.apache.org/jcr/sling/1.0"
xmlns:jcr="http://www.jcp.org/jcr/1.0"
jcr:primaryType="sling:OsgiConfig"
org.apache.sling.commons.log.file="/var/log/custom.log"
org.apache.sling.commons.log.level="debug"
org.apache.sling.commons.log.pattern="\{0\}"
org.apache.sling.commons.log.names="[com.myproject.custom]" />
* Deploy Configuration:
* Save the configuration file and deploy it to the appropriate environment. The logging system in AEM will pick up this configuration and create a custom log file with the specified settings.
