Monitor MongoDB with Nagios XI - How to perform this ?
This article covers how to monitor a MongoDB server with Nagios XI using the MongoDB Server Configuration Wizard in order to monitor the health of your server. The
wizard supplies checks to monitor the following: number of queries per second, memory usage, the number of databases on the server, and percentage of free connections available.
To Connect to MongoDB with the appropriate privileges:
Connect to mongod or mongos with the privileges specified in the Prerequisites section.
