MongoDB is a document-oriented NoSQL database. Metricly can be used to monitor your MongoDB’s performance.
Prerequisites The Linux Agent must be setup before you proceed with the MongoDB integration.
Configure Navigate to the collectors folder, /opt/netuitive-agent/conf/collectors. Open the MongoDBCollector.conf file. Change the enabled setting to True. Replace the default host address and/or port number if necessary. Save the configuration file, and restart the Linux Agent. Due to the large number of metrics generated by MongoDB, you shouldn’t monitor more than one MongoDB host per agent.
