Who is this for?

This is an introductory topic for developers, DevOps engineers, and platform engineers who want to implement infrastructure and application monitoring using Dynatrace on Arm-based cloud environments.

What will you learn?

Upon completion of this Learning Path, you will be able to:

  • Deploy Dynatrace OneAgent on Azure Cobalt 100-based Arm64 virtual machines (VMs)
  • Configure Dynatrace ActiveGate for secure monitoring communication
  • Monitor system resources, processes, and services using Dynatrace
  • Validate application monitoring using a sample NGINX workload

Prerequisites

Before starting, you will need the following:

  • A Microsoft Azure account with access to Cobalt 100 based instances (Dpsv6)
  • Basic knowledge of Linux command-line operations
  • Familiarity with SSH and remote server access
  • Basic understanding of cloud infrastructure and monitoring concepts

You’ll deploy Dynatrace OneAgent on an Azure Cobalt 100-based Arm64 virtual machine and configure Dynatrace ActiveGate for secure communication with Dynatrace SaaS. You’ll provision a Dpsv6 VM, allow TCP port 9999 in its Network Security Group, install both components on Ubuntu 24.04 LTS, and validate monitoring with a sample NGINX workload. By the end, you’ll have host-level visibility and a route for Dynatrace communication through ActiveGate.

?
Can I create the Cobalt 100 VM with the CLI or IaC instead of the Azure Portal?
Yes. There are several ways to create a Cobalt 100 VM, but this path uses the Azure Portal. Choose the method that best fits your workflow.
Which Azure VM series should I select for this walkthrough?
Use a general-purpose Dpsv6 series VM based on Azure Cobalt 100.
Which Linux image and architecture do I need for installing OneAgent and ActiveGate?
Use Ubuntu 24.04 LTS Arm64. Both Dynatrace OneAgent and ActiveGate operate natively on Arm64 (aarch64).
Do I need to open any ports for ActiveGate, and where do I configure it?
Yes. Open TCP port 9999 in the Azure Network Security Group attached to the VM’s network interface or subnet to allow Dynatrace communication to ActiveGate.
How do I confirm that monitoring works, including the sample NGINX workload?
After installation, OneAgent connects to your Dynatrace SaaS environment and starts monitoring system processes and services. Deploy the sample NGINX workload and check that NGINX appears among the monitored processes and system metrics update.
