MongoDB is one of the leading NoSQL databases that is built as a response to scalability, performance, and high availability. This document-based database can be deployed either in stand-alone or clustered operational mode. Moein Monitoring system supports monitoring of MongoDB in both aforementioned modes. In this regard, key performance indicators of databases, replicas, shards, operations, transactions, and so on are collected. In addition, in the case of clustered deployment, cluster’s nodes are also monitored. List of the monitored performance metrics of this database is as follows.

MongoDB database monitoring includes the following:
