I have a log4j2.xml file and I want to generate a new logs file in it. The format of the logs file is as follows.
datetime | user | page | action
Here the user name is the current login user which is given by default in OpenSIMs such as admin.
Here page is a page created using the sitemap feature in opencms 19 version.
Here action is the page created using the sitemap feature in opencms 19 version. What action has been done on that page, such as if a user edited it, if a user deleted a particular content, the action should come like this
Finally, if I want to create logs with this requirement, please give me guidance on what steps to follow, such as what pattern to add.
