Release notes

Overview

The MongoDB Extension connects to your MongoDB servers either remotely and locally.
Collective batch of data is gathered every minute by this extension and sent to the Dynatrace platform for detailed analysis.

This is intended for users, who:

Would like to monitor database traffic for optimization plan

This enables you to:

Monitor database operations with a comprehensive dashboard
Take pre-emptive measures to avoid service degradations

Get started

Prerequisites:

Either :
- Dynatrace OneAgent installed on your MongoDB Server
- Dynatrace ActiveGate installed and with network access to your MongoDB Server
MongoDB User with serverStatus@admin, listDatabases and dbStats permissions.
- The MongoDB Built In Cluster Monitor Role has these permissions already set up.

After the prerequisites are done, enable the extension via the Dynatrace Hub
Choose to monitor remotely via an ActiveGate group or locally via the OneAgent
Enter in configuration and credentials
Review data in included Dashboard

Details

Along with the username and password you can configure the extension to :

Use a different Authentication Database (Sets the authSource property in the connection string)
Add a path to a CA PEM File (Sets the tlsCAFile argument of the MongoClient)
Add a path to a Client Certificate (Sets the tlsCertificateKeyFile of the MongoClient)
- Note: These file paths need to be accessible on all ActiveGates in the group or locally on the OneAgent Host
Select between MongoDB Auth Mechanisms - SCRAM-SHA-1, SCRAM-SHA-256, PLAIN, DEFAULT
- If no mechanism is specified, PyMongo automatically uses SCRAM-SHA-1 when connected to MongoDB 3.6 and negotiates the mechanism to use (SCRAM-SHA-1 or SCRAM-SHA-256) when connected to MongoDB 4.0+.
