+# Agent Check: Hyper-V
+
+## Overview
+
+This check monitors [Hyper-V][1] through the Datadog Agent.
+
+## Setup
+
+### Installation
+
+The Hyper-V check is included in the [Datadog Agent][2] package. No additional installation is needed on your server.
+
+### Configuration
+
+1. Edit the `hyperv.d/conf.yaml` file, in the `conf.d/` folder at the root of your Agent's configuration directory to collect your Hyper-V performance data. See the [sample hyperv.d/conf.yaml][3] for all available configuration options.
+
+2. [Restart the Agent][4].
+
+### Validation
+
+[Run the Agent's status subcommand][5] and look for `hyperv` under the Checks section.
+
+## Data Collected
+
+### Metrics
+
+See [metadata.csv][6] for a list of metrics provided by this integration.
+
+### Service Checks
+
+Hyper-V does not include any service checks at this time.
+
+### Events
+
+Hyper-V does not include any events at this time.
+
+## Troubleshooting
+
+Need help? Contact [Datadog support][7].
