Disk

Agent Check Agent Check

Supported OS: Linux Mac OS Windows

Overview

Collect metrics related to disk usage and IO.

Setup

Installation

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

Configuration

The disk check is enabled by default, and the Agent collects metrics on all local partitions. If you want to configure the check with custom options, Edit the disk.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory. See the sample disk.d/conf.yaml for all available configuration options.

Validation

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