If there are still files left on the system following an  apt-get remove mongo , try and run the command again with the  --purge  switch, using a wildcard search for the name: sudo apt-get remove mongodb* --purge

Ref: http://stackoverflow.com/questions/15204341/mongodb-logging-all-queries I ended up solving this by starting mongod like this (hammered and ugly, yeah... but works for development environment): mongod --profile=1 --slowms=1 & This enables profiling and sets the threshold for "slow queries" as 1ms, causing all queries to be logged as "slow queries" to the file: /var/log/mongodb/mongodb.log Now I get continuous log outputs using the command: tail -f /var/log/mongodb/mongodb.log An example log: Mon Mar 4 15:02:55 [conn1] query dendro.quads query: { graph: "u:http://example.org/people" } ntoreturn:0 ntoskip:0 nscanned:6 keyUpdates:0 locks(micros) r:73163 nreturned:6 reslen:9884 88ms
