Logging question

I have been using the Slantwise Fetcher plugin for a while now.

I have run into some problems lately and it's a bit of a pain to
troubleshoot because it is not clear where (or if) it logs anything.

Can anybody give me some pointers about how to enable logging for this?

It would be great if I could have separate logs for each fetcher. I am
running several as I am checking numerous mailboxes.
