What is the Datadog Agent?
The Datadog Agent is a lightweight, open-source software that runs on your hosts. Its core functions include:
Collecting metrics and logs from your systems and services
Sending this data to Datadog for analysis and visualization
Providing real-time visibility into your infrastructure's performance
The agent acts as a bridge between your Windows machine and the Datadog platform, enabling you to monitor, troubleshoot, and optimize your applications and infrastructure effectively.
Prerequisites
Before you begin the installation process, ensure you have the following:
A Windows machine (supported versions: Windows Server 2008r2 or later)
Administrator privileges on the Windows machine
A Datadog account (If you don't have one, sign up for a free trial)
Your Datadog API key (You can find this in your Datadog account settings)
