One random thing I've noticed about serinus is that it seems to drop
UDP packets more than others, but dragonet apparently doesn't:
tmunro=> select animal, count(*) from run where result = 'FAILURE' and
'stats' = any(fail_tests) and snapshot > now() - interval '3 month'
group by 1 order by 2 desc;
animal | count
--------------+-------
serinus | 14
flaviventris | 6
mandrill | 2
bonito | 1
seawasp | 1
crake | 1
sungazer | 1
(7 rows)
