Best MongoDB Monitoring Tools for 2023

Monitoring is an essential part of all database administration. A solid understanding of MongoDB Monitoring Tools will allow you to assess the state of your database and keep your deployment running smoothly.

Unlike SQL database systems, the MongoDB database is built on a document system that allows you to seamlessly index, query, and sort data. In a nutshell, it stores data in JSON-like documents rather than tables. It is a distributed database with dynamic schemas for unstructured data, high availability, and horizontal scaling built-in. Furthermore, it is completely free to use.


What is MongoDB?

MongoDB is an open-source NoSQL-based DBMS, which has a free version too. MongoDB stores and retrieves data as a key-value pair but the value part is stored as a document in JSON/XML format.  Hence you can store a lot of details about an object in its document, and similar objects can have different length documents( i.e. some can have more properties than others) associated with them. 

Due to its internal structure, MongoDB is mostly used for CMS systems, blogging platforms, real-time analytics & e-commerce applications.
MongoDB indexes, queries, and processes documents instead of singular column values, and is inherently distributed in nature. 

Key Features of MongoDB

When compared to other traditional databases, MongoDB has a number of distinguishing features that make it a superior solution. Some of these characteristics are discussed in greater detail below:

Fewer Schemas in a Database: A Schema-Less Database allows you to store different types of Documents in a single Collection (the equivalent of a table). An Indexed Document: Every field in a MongoDB Database Document is indexed with Primary and Secondary Indices, which makes it easier to retrieve information from the data pool. Scalability: A large amount of data is partitioned into data chunks using the Shard Key, and these data chunks are evenly distributed across Shards that span many Physical Servers. Replication: MongoDB ensures high data availability by replicating the data and sending it to multiple servers so that if one fails, the data can still be retrieved from another.

What is the need for MongoDB Monitoring Tools? 

Although MongoDB has built-in scaling, security, and fault tolerance;  it’s better to continuously monitor your MongoDB infrastructure to proactively mitigate risks and ensure smooth functioning. 

Another important aspect of database administration is advanced capacity planning for your application and monitoring your cluster’s health and performance.  

Monitoring MongoDB databases allows you to:- 

Better understand your databases and how they work together, realize if any design improvements are required  Optimize resources utilization and reduce costs  Detect and correct any anomalies, undesired boundary conditions, presence of abnormal behavior, and performance issues Mitigate risks and handle attacks if any  Comply with standard security/data protection/governance recommendations and statutory obligations.

Typically you would want to measure and track indicators like:- 

Key performance indicators and variables  Software and hardware metrics  Cluster’s operations and connections metrics  Network and bandwidth usage  Metrics related to your infrastructure stack

What are Some Modern and Relevant MongoDB Monitoring Tools?

We will discuss the key differentiators between available options. Also, we will try to discuss use cases where a typical solution fits best.  

If you’re not sure how big your infrastructure and MongoDB cluster will grow, you must choose a tool that works and scales well with single as well as multiple installations. 

If you’re sensitive to performance, throughput, and outages, then tools that additionally give you cloud resource monitoring and infrastructure usage statistics, will be useful for you. If performance is of prime concern, then APM Tools (Application Performance Monitoring) is what you should be using. 

1. MongoDB’s Free Cloud Monitoring Tool

To enable real-time reporting of your running MongoDb instance, MongoDB offers “Free Cloud monitoring” for standalone or replica sets.

Just call db.enableFreeMonitoring() to enable it. 

MongoDB also provides certain functions like mongostat and mongostop, bundled with its distribution binaries, for this purpose. 

mongostat returns the latest information about the database operations by type (e.g. insert, query, update, delete, etc.); it’s useful incapacity planning.   mongotop tracks and reports the current read and write activity of a MongoDB instance, it’s useful in monitoring resource usage and database activity. 

There are specific commands that give you a lot more details about the processes happening in your databases(s), like server-status/collStats/dbStats/replSetGetStatus, etc. If you have programming and designing resources with you, you can directly use the above functions to create your reports/visualizations. 

These tools will give you fine-grained control over your measures, and help eliminate noise( unimportant metrics) to let you focus on only those metrics that matter for your application. 

2. MongoDB Atlas’s Performance Panel  

MongoDB Atlas is a SAAS offering by MongoDB, which runs your databases on the cloud and takes care of all administration/configuration/scaling tasks.

MongoDB Atlas provides tools like Performance Panel, Performance Advisor, and Query Profiler, to monitor your databases running in this cloud service.

It has a “Metrics” tab that shows visualizations related to process metrics, hardware metrics, and database metrics. These metrics are refreshed every 20 minutes to give you the latest information. Moreover, you can adjust certain factors about the visualizations being shown, like Granularity/Zoom level/Display Annotations/Show Counters/Add or Toggle Charts, etc. 

While viewing these charts you can view its detailed description, zoom in, expand it, View statistics at a particular time and move the chart. So, delving into deeper details is easy and possible with just a few clicks. 

MongoDB Atlas also allows you to view real-time metrics by clicking the View Monitoring button. You can view the real-time performance panel to view CPU, Disk Util, and Sys Mem/Connections, Network In, Network Out/Reads & Writes/Query Execution Times/Slow queries /Hottest collections, etc. You can view additional details about each metric, e.g. CPU time slices used by modules such as user, kernel, iowait, steal, etc. 

So, this lets you easily decide which collections/instances to give more resources to. Since this is a tool developed by MongoDB itself, it’s very accurate and easy to use. If you’re using MongoDB Atlas, these tools can be a good option. 

Next, we will discuss some 3rd party tools recommended by MongoDB. 

3. PandoraFMS MongoDB-Monitoring Plugin

Pandora FMS provides the PandoraFMS-MongoDB-monitoring plugin to monitor the main variables and configuration parameters of your MongoDB.
