I was wondering what, if any, software you use for monitoring your relays. It would be nice if I could get an email when the Tor daemon crashes, and maybe another every night telling me about bandwidth used, average speed, etc.
For external monitoring, I wrote a Nagios check using Stem. It is available at:
