Nice to see someone else scripting away

Although those params aren't currently available, you can get the info (or approximations thereof) in a few ways, depending on when & how you want the info:
1. Use the altbinz_status.xml file (this can give you updates on queue size and speed).
2. Use TheKarn's abzQueueReader.dll to read the queue.abz file (pm him!).
3. Parse your log file.

I think this should give you the last two bits of info you need with only a bit of light regexing.

Look forward to reading & testing your script!
