FAQPage Schema
How do I install the Datadog Agent on Linux via SSH?▼

You can install the Datadog Agent on Linux via SSH by using Single Step Instrumentation (SSI), which automates agent onboarding without changing application code. Provide target host details, SSH credentials, and environment variables to begin.

What is Single Step Instrumentation for Datadog onboarding?▼

Single Step Instrumentation (SSI) is an automated onboarding process that deploys the Datadog Agent to instrument applications without code changes. It guides credential gathering, prerequisite validation, installation, and agent verification.

Do I need sudo privileges to deploy the Datadog Agent on Linux hosts?▼

Yes, deploying the Datadog Agent on Linux hosts requires SSH access with sudo privileges. You also need properly configured environment variables, specifically DD_API_KEY and DD_SITE, to run the installer and verify agent status.

Can I use SSI to automate Datadog Agent setup on bare-metal and cloud Linux instances?▼

Yes, SSI applies to both bare-metal and cloud Linux instances where the Datadog Agent is not yet installed. It reduces manual setup time by validating prerequisites, installing the agent, and verifying hostname registration.

What environment variables are required to run the Datadog Agent installer?▼

You must configure the DD_API_KEY and DD_SITE environment variables to run the Datadog Agent installer via SSH. These variables are essential for executing the installation and verifying the agent's health and registration.

Does installing the Datadog Agent with SSI require modifying my application code?▼

No, installing the Datadog Agent with SSI automates onboarding to instrument applications without code changes. The guided process handles infrastructure discovery and agent health verification directly through the SSH connection.
