Chapter 2. Installing the Ceph Integration
To install the Ceph integration, log in to the Datadog App. The user interface will present navigation on the left side of the screen. Click Integrations. Either enter ceph into the search field or scroll to find the Ceph integration. The user interface will present whether the Ceph integration is available or already installed. If it is available, click the button to install it.

Installing the Datadog Agent for Ceph
To install the Datadog agent for Red Hat Ceph Storage, log in to the Datadog App. The user interface will present navigation on the left side of the screen. Click Integrations. To install the agent from the command line, click on the Agent tab at the top of the screen.

For Red Hat Ceph Storage on RHEL 7 or Ubuntu 16.04, open a command line. Then, enter the one-step command line agent installation. For example:
# DD_API_KEY=<key-string> bash -c "$(curl -L https://raw.githubusercontent.com/DataDog/dd-agent/master/packaging/datadog-agent/source/install_agent.sh)"
Copy the example from the Datadog user interface, as the key differs from the example above and with each user account.
