7 This check monitors the number of read, write and total locks
8 for the active clients and queued operations on a MongoDB instance.
9 You can configure levels for the read, write and total count.
10 Without configuration this check is always OK.
12 Note: If the MongoDB is running as a replica set, this check is not discovered
13 on the same host where the {mk_mongodb} plugin is installed. The data is piggybacked
14 to a pseudo host named after the replica set name, intead.
