Answer 1: absence of any errors logged. Then just trust. :)

Answer 2: Use a Tor controller. Vidalia has a "who has used my bridge
lately?" button you can push to learn by-country statistics. Or try
'arm' if you prefer command-line controllers.

Answer 3: We publish sanitized bridge descriptors on the metrics site:
https://metrics.torproject.org/data.html#bridgedesc
We're working on usable interfaces to let you look up the descriptor
for your bridge (including the usage statistics that it publishes). Stay
tuned.

Which distribution strategy the bridgedb service picks for your bridge
will influence how much use it sees.
https://metrics.torproject.org/data.html#bridgeassignments
But you shouldn't necessarily be worried if it sees low usage: a bridge
with high usage is probably going to be blocked soon, whereas a bridge
with low usage can remain useful for longer. We need both kinds. Also
also, the need for bridges comes in waves, so today's demand isn't a
good predictor of next month's demand.

Hope that helps,
