Can slowms be set on each individual database in MongoDB?
setProfilingLevel actually affects two things. First parameter (level) tells when system writes to profile -collection (0-never, 1-only when slower than slowms or 2-always). Second parameter (slowms) affects actually always to syslog output of ALL databases. So, with db.setProfilingLevel(0,-1), nothing is ever written to profile-collection, but ALL queries (of all DBs) are written to mongod.log
