Log4j NDC and SecureFileTransferClient

Question

So I'm trying to use Log4j's Nested Diagnostic Context (NDC, http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/NDC.html), but it acts on a per-thread basis. When I operate at higher logging levels, since edtFTPj/PRO starts multiple threads, those additional threads don't inherit the NDC I set. Is there any way to have these threads automatically set this? Or any way to provide a custom ThreadFactory in order to create Thread's which set the NDC I want?

Answer 1

No, I don't think you can do this.

Answer 2

Could this be a feature (thread startup hook, or a specific NDC startup hook) feature in a future version? What we're really trying to do is positively identify what logging messages in the log file come from different parts of the application, and since we will have multiple SecureFileTransferClient connected to separate FTP/SFTP servers, we'd like to easily tell which one is outputting which log messages.
