MongoDB Instrumentation with .NET APM Agent

Atatus .NET APM traces MongoDB commands issued through the official MongoDB.Driver (2.4.4+), creating a span for each command inside an active transaction.

Package installation

Add the Atatus MongoDB instrumentation package to the application.

dotnet add package Atatus.MongoDb --version 3.2.2

Configure the MongoDB client

A prerequisite for auto-instrumentation is to configure the MongoClient with MongoDbEventSubscriber in your database initialization code:

using Atatus.NetCoreAll;
using Atatus.MongoDb;

var settings = MongoClientSettings.FromConnectionString(mongoConnectionString);
settings.ClusterConfigurator = builder => builder.Subscribe(new MongoDbEventSubscriber());
var mongoClient = new MongoClient(settings);

In certain cases you may need to manually activate auto-instrumentation by passing MongoDbDiagnosticsSubscriber to the Agent.Subscribe method:

using Atatus;
using Atatus.MongoDb;

Agent.Subscribe(new MongoDbDiagnosticsSubscriber());

What Atatus captures ?

• A span for each command executed through the MongoDB.Driver client.
