MongoDB (local or remote monitoring)

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

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.

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

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)
  • Note: This file path needs 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+.

Q: What is the Custom Metric Usage of this extension?

A: The formula for consumption of the extension is:

Note : Activating the extension locally would consume the included metrics per host unit

Per connected process/port -> (17 + 5 * <# of Databases>)
