Dynatrace Architecture and Components: A Comprehensive Guide

Introduction

Dynatrace is a full-stack observability platform designed to monitor, analyze, and optimize the performance of applications, infrastructure, and user experience in real-time. It utilizes AI-driven insights and automation for faster problem resolution and performance improvements.

This guide provides a detailed understanding of the Dynatrace architecture, including components and deployment patterns ranging from small environments (single host/cloud) to large-scale enterprise environments (multi-cloud, hybrid, global).

Core Components of Dynatrace Architecture

1. Dynatrace OneAgent

• Installed on each monitored host (physical, virtual, container).
• Automatically discovers and monitors processes, services, and dependencies.
• Collects metrics, logs, traces, and topology data.
• Supports auto-instrumentation for many technologies.

2. Dynatrace ActiveGate

• Acts as a communication proxy between OneAgents and Dynatrace Cluster (SaaS or Managed).
• Handles traffic encryption, compression, and routing.
• Also used for:
  • Synthetic monitoring
  • Cloud API integrations (AWS, Azure, GCP)
  • Remote monitoring of internal networks

3. Dynatrace Cluster (SaaS or Managed)

• Central processing and analysis engine.
• Stores metrics, logs, events, and traces.
• Provides the web UI for dashboards, Smartscape, PurePath, Davis AI insights, alerts.
• Available in two forms:
  • Dynatrace SaaS: Hosted by Dynatrace.
  • Dynatrace Managed: Self-hosted in your infrastructure.

4. Davis AI Engine

• Dynatrace’s AI for automatic anomaly detection, root cause analysis, and alerting.
• Analyzes metrics, logs, traces, and events in real-time.

5. Smartscape Topology Model

• Visualizes dynamic relationships between infrastructure, services, and applications.
• Continuously updates based on real-time data.

6. PurePath Technology

• End-to-end distributed tracing engine.
• Follows every transaction across tiers (frontend to DB).
• Captures timings, call trees, and exceptions.

7. AppEngine and Extensions

• AppEngine: Custom observability apps using Dynatrace data.
• Extensions: Plugins for third-party systems like network devices, storage, etc.

Deployment Architectures by Size

Small Setup (Single App / Host / Cloud Instance)

Component	Setup Detail
OneAgent	Installed on the single VM/host
ActiveGate	Optional (SaaS uses internet directly)
Cluster	Dynatrace SaaS recommended
Features Enabled	Full-stack, RUM, Log Monitoring, PurePath

Use Case: Monitoring a small app or VM on AWS EC2, Azure VM, or a single Docker host.

Medium Setup (10-100 Hosts / Cloud VMs / Microservices)

Component	Setup Detail
OneAgent	Installed on all application/infrastructure nodes
ActiveGate	Installed for cloud monitoring and communication optimization
Cluster	SaaS or Managed (for regulatory/compliance needs)
Network Zones	Optional: Used to segment agents by region or zone
Features Enabled	Full-stack, Smartscape, Davis AI, Logs, RUM, Kubernetes Support

Use Case: Microservices in Kubernetes, Azure, or hybrid deployments.

Large Setup (Enterprise Multi-Cloud / Hybrid / 1000+ Hosts)

Component	Setup Detail
OneAgent	Installed via automation (Ansible, Helm, etc.) across all nodes
ActiveGate	Multiple ActiveGates per region/data center
Cluster	Managed preferred (for data residency); scalable to multiple cluster nodes
Cluster Scaling	Horizontal scaling via multiple cluster nodes
Network Zones	Strongly recommended for performance and data control
Synthetic Locations	Private/public synthetic locations with ActiveGates
Features Enabled	All features incl. security monitoring, cloud APIs, custom metrics, etc.

Use Case: Global organizations running apps across AWS, Azure, GCP, on-prem, and private clouds.

Network and Security Considerations

• TLS Encryption: All communication between OneAgent, ActiveGate, and Cluster is encrypted.
• Ports:
  • OneAgent → ActiveGate: 9999 (default)
  • ActiveGate → Cluster/SaaS: 443
• Proxy Support: ActiveGate supports outbound proxy for restrictive environments.
• Data Privacy: Supports GDPR compliance, role-based access control, and data masking.

Best Practices

1. Use Network Zones for large setups to isolate traffic and optimize routing.
2. Leverage Auto-Tagging to structure data and dashboards by environment, service, team.
3. Deploy ActiveGates strategically to reduce internet bandwidth and improve redundancy.
4. Automate OneAgent deployment using scripts, Helm (K8s), Ansible, Terraform, etc.
5. Integrate with CI/CD and CM tools to enable monitoring in Dev, QA, and Prod stages.
