IF the tracker provides this information, t.get_scrape_* (complete/ 
incomplete/downloaded).

If the tracker doesn't provide it, you cannot get it from rtorrent.

Not particularly. The number of seeds can be very misleading (if  
there are many seeds but they're all unconnectable or throttled by  
their ISP or just generally slow). The number of leechers is an  
indication of popularity, but not really health. You could check the  
chunk statistics (esp. number of distributed copies), but I don't  
think that's available via xmlrpc.

The only decent indicator I can think of is the average download  
speed of the other non-seeders, which you get from p.get_peer_rate.
