Overview

The .NET integration allows you to collect and monitor your .NET application logs, traces, and custom metrics.

Setup

Metric collection

See the dedicated documentation for collecting .NET custom metrics with DogStatsD.

Trace collection

See the dedicated documentation for instrumenting your .NET application to send its traces to Datadog.

Log collection

Available for Agent v6.0+

See the dedicated documentation on how to setup .NET log collection to forward your logs to Datadog.

Profile collection

See the dedicated documentation for enabling the .NET profiler.

Data Collected

Metrics
