MongoDB Operation Counters
This check monitors the number of operations and replicated
operations for a MongoDB instance. It is always OK.
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.
Operations and Replica Operations.
Creates a service for the Operations and another one for Replica Operations (if applicable).
