Introducing Free Cloud Monitoring for MongoDB

With the release of MongoDB 4.0, we’re excited to announce the availability of free cloud monitoring, the easiest way to monitor and visualize the status of your MongoDB deployments.

There are no agents to install, no forms to fill out, no sign-ups necessary.

Let’s walk through how it works.

After you’ve installed MongoDB 4.0, connect to your instance(s) using the mongo shell, the interactive JavaScript interface to MongoDB. You should see the following message.

MongoDB shell version v4.0.0
connecting to: mongodb://
MongoDB server version: 4.0.0
Enable MongoDB's free cloud-based monitoring service to collect and display
metrics about your deployment (disk utilization, CPU, operation statistics,

The monitoring data will be available on a MongoDB website with a unique
URL created for you. Anyone you share the URL with will also be able to
view this page. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command:

When you run the command, you should see something similar to what’s shown below.

    "state" : "enabled",
    "message" : "To see your monitoring data, navigate to the unique URL below. Anyone you share the URL with will also be able to view this page. You can disable monitoring at any time by running db.disableFreeMonitoring().",
    "url" : "",
    "userReminder" : "",
    "ok" : 1

Simply copy and paste your unique URL into a browser to access your monitoring dashboard. Free cloud monitoring tracks key performance indicators such as operation execution times, disk utilization, memory, network input/out, and more in interactive charts.

Mousing over chart lines reveal precise metrics.

You can also zoom in to 1 minute granularity.

Free cloud monitoring supports standalone instances and replica sets of MongoDB 4.0+. Of course, only monitoring metadata is accessed, never the contents of your databases. You can disable monitoring and your unique URL at any time by running the db.disableFreeMonitoring() command.
