There are many articles how to create your own logger and save a log file into a separate folder. I need something else. My items represent the processors. It means I can click the button on the ribbon and run associated process by item id. Here is what I want to get.

  1. When process is started, the new log file should be created where file name is \Data\logs[customfolder][itemid][timestamp].txt
  2. Even process is finished and I run it again a new log file should be created.

Do you have an idea or solution how to implement it?

  • yes, I did. The solution is used in Sitecore Data Exchange Framework. Each time when pipeline batch is run a new log file is created.

As Sitecore logging is just a wrapper on top of log4net, you should create an appender (and maybe logger) in your code (assuming that the "processor" you mention is some custom code). I found this solution on stackoverflow, but didn't test it myself. It is using the log4net api to create a FileAppender and set its properties. After creating the appender, you must add it to the logger you want to use for writing logs.

  • Thank you for respond. That is a something I've already seen. What I am interested more is to reuse as much sitecore API as it possible. For example SitecoreLogFileAppender resolves the path but method MapPath is private and etc. If I create my custom appender and sitecore will change the default solution I need to care about updating my api. However, it is ok. I can use a reflection and sitecore factory or LoggerManager to get what i need from configuration.
