This check monitors the amount of resident, virtual and mapped memory
for a mongodb instance. You can configure levels for each object.
Furthermore this check validates if the virtual memory is much higher (3 times)
than the mapped memory. This indicates a possible memory leak
in the database. The check reports WARN in this scenario.
Note: If the MongoDB is running as a replica set, this check is not discovered
on the same host where the
mk_mongodb plugin is installed. The data is piggybacked
to a pseudo host named after the replica set name, intead.
One service is created.
