Datadog agent on AWS EC2 using install_script_agent

How to send Traces from Datadog agent running in EC2 to CodeSee

Service Maps is an Enterprise-only feature

Summary

This guide will help you send trace data from your Datadog agent to CodeSee when the agent is running on AWS EC2 and installed using the install_script_agent script.

We need to set the apm_config > additional_endpoints parameter in your datadog.yaml file, but the install script ignores the environment variable that we would typically use to set this parameter. So, the script below appends the parameter to the datadog.yaml specifically.

Install Datadog agent on AWS EC2

Create a user-data.sh and copy its content into User Data when launching your EC2

Please refer to AWS doc on where to put your User Data: user data doc
