Get metrics from ASP.NET in real time to:

  • Visualize and monitor ASP.NET states.
  • Be notified about ASP.NET failovers and events.



The ASP.NET check is included in the Datadog Agent package, so you don’t need to install anything else on your servers.


  1. Edit the aspdotnet.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your ASP.NET performance data. See the sample aspdotnet.d/conf.yaml for all available configuration options.

  2. Restart the Agent

Note: Versions 1.9.0 or later of this check use a new implementation for metric collection, which requires Python 3. For hosts that are unable to use Python 3, or if you would like to use a legacy version of this check, refer to the following config.

Log collection

ASP.NET uses IIS logging. Follow the setup instructions for IIS in order to view logs related to ASP.NET requests and failures.

Unhandled 500 level exceptions and events related to your ASP.NET application can be viewed with the Windows Application EventLog.


Run the Agent’s status subcommand and look for aspdotnet under the Checks section.
