A few show tricks to find slow queries in mongodb

Enable profiling

First, you have to enable profiling

db.setProfilingLevel(1)

Now let it run for a while. It collects the slow queries ( > 100ms) into a capped collections, so queries go in and if it's full, old queries go out, so don't be surprised that it's a moving target...
