MongoDB Memory

Distribution: official part of Check_MK
License: GPL
Supported Agents: Linux

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.
