Datadog Agent Agent not collecting IIS metrics

What is Datadog Agent Agent not collecting IIS metrics

Understanding Datadog Agent

Datadog Agent is a powerful tool designed to collect metrics, logs, and traces from your infrastructure and applications. It provides real-time visibility into your systems, helping you monitor performance and troubleshoot issues efficiently. One of its capabilities is to collect metrics from Internet Information Services (IIS), a popular web server for hosting websites and applications on Windows servers.

Identifying the Symptom

When the Datadog Agent is not collecting IIS metrics, you may notice missing data in your dashboards or alerts related to IIS performance. This can hinder your ability to monitor the health and performance of your web applications hosted on IIS.

Exploring the Issue

The primary reason for the Datadog Agent not collecting IIS metrics is that the IIS integration is not enabled or properly configured. Without this configuration, the Agent cannot gather the necessary data from IIS to send to Datadog.

Common Causes

IIS integration is not enabled in the Datadog Agent configuration. Incorrect or missing configuration settings for IIS monitoring. Network issues preventing the Agent from communicating with the Datadog platform.

Steps to Fix the Issue

Follow these steps to enable and configure IIS metrics collection in the Datadog Agent:

Step 1: Enable IIS Integration

Open the Datadog Agent configuration directory. On Windows, this is typically located at C:\ProgramData\Datadog\. Locate the conf.d\iis.d\ directory. If it does not exist, create it. Create a configuration file named conf.yaml within the iis.d directory. Add the following content to conf.yaml to enable IIS metrics collection:

init_config:instances: - host: "." tags: - "environment:production"

Step 2: Restart the Datadog Agent

After saving the configuration file, restart the Datadog Agent service to apply the changes. You can do this via the Windows Services Manager or by running the following command in an elevated command prompt:

net stop datadogagent && net start datadogagent

Step 3: Verify Configuration

Check the Agent status to ensure that the IIS integration is active. Run the following command:

datadog-agent status

Look for the IIS integration in the output and verify that it is collecting metrics.
