MongoDB Atlas extension
- Latest Dynatrace
- Extension
- Published Oct 27, 2025
Monitor your SaaS installation of MongoDB (Atlas) remotely.
Monitor your MongoDB Atlas projects via ActiveGate and the MongoDB Atlas Administration API.
Get started
Use cases
For SaaS deployments of MongoDB where the Dynatrace OneAgent cannot be installed. This extension enables insights into the overall health of your Atlas projects, clusters and nodes.
Requirements
- Find your atlas project ID
- Create Org API key
- Whitelist the ActiveGate IP address under the API Key access list
Compatibility information
Only compatible with MongoDB Atlas
Activation and setup
Activate the extension in your environment using the in-product Hub. Provide the required configuration settings, such as the project ID and API access keys. Follow the instructions and prompts within the extension settings.
Details
This extension uses the Atlas Administration API to fetch important metrics and metadata for your projects, clusters, and nodes.
DQL and Logs
You can set the extension to fetch important project events as Dynatrace log events.
-
If enabled, all Mongo events are ingested into Dynatrace.
To learn more about the list of events, see
- The
eventTypeparameter of the listProjectEvents API. - Mongo alert-types. Note that not all supported Atlas events might be referenced.
- The
-
You can specify a comma-separated list of events to collect if you want to ingest only specific event types, for example
CREDIT_CARD_ABOUT_TO_EXPIRE, NO_PRIMARY, CPS_SNAPSHOT_FALLBACK_FAILED, NDS_X509_USER_AUTHENTICATION_MANAGED_USER_CERTS_EXPIRATION_CHECK.
All events are ingested as Info severity logs. You can configure log processing rules in Dynatrace to automatically raise this severity for specific event types.
Licensing and cost
The metrics and events collected through this extension consume Dynatrace Davis Data Units (DDUs).
- The extension monitors all clusters (deployments) within a Mongo Atlas project.
- Each cluster then has a number of nodes (processes) which is where the metrics are collected from.
- If you also want to collect disk metrics, then the disk metrics are collected from each node partition.
So, a general formula for the number of metrics would be:
- Process Metrics (Total = 108):
num_process_metrics = Number of projects * Clusters in project * Nodes per Cluster * 108 - Disk Metrics (Total = 18):
num_disk_metrics = Number of projects * Clusters in project * Nodes per Cluster * Partitions per Node * 18 - Total metrics:
Total_metrics = num_process_metrics + num_disk_metrics
You can use the feature sets defined below to enable/disable the collection of specific metric categories.
Feature sets
When activating your extension using monitoring configuration, you can limit monitoring to one of the feature sets. To work properly the extension has to collect at least one metric after the activation.
In highly segmented networks, feature sets can reflect the segments of your environment. Then, when you create a monitoring configuration, you can select a feature set and a corresponding ActiveGate group that can connect to this particular segment.
All metrics that aren't categorized into any feature set are considered to be the default and are always reported.
A metric inherits the feature set of a subgroup, which in turn inherits the feature set of a group. Also, the feature set defined on the metric level overrides the feature set defined on the subgroup level, which in turn overrides the feature set defined on the group level.
