1. The clouds #
APIs and logs.
Integrations #
| Cloud | Metrics | Logs |
|---|---|---|
| AWS | CloudWatch integration (IAM role) or streaming metrics | Amazon Data Firehose to Dynatrace |
| Azure | Azure Monitor integration (service principal) | Event Hub to Dynatrace |
| GCP | Cloud Monitoring integration (service account) | Pub/Sub to Dynatrace |
Good practice: Install OneAgent on cloud virtual machines in addition to the integration: the integration provides the provider's metrics, OneAgent the visibility into processes and services.
2. Extensions 2.0 #
What OneAgent cannot see.
Principle #
Extensions 2.0 (Dynatrace Hub) collect data from devices and technologies without OneAgent: switches and routers (SNMP), databases (SQL queries), remote JMX, Prometheus exporters. They run in an ActiveGate group for redundancy.
- Enable the extension from the Hub, choose the ActiveGate group, fill in the endpoints and credentials (credential vault).
- Metrics arrive with their entities, linked to the topology and to Davis problems.
Good to know: Dynatrace evolves very quickly (new platform, Grail, apps): check screen names and API versions in your environment's documentation.

Course Glossary
AIOps (Artificial Intelligence for IT Operations)
The use of artificial intelligence and machine learning to automate and improve IT operations (e.g., anomaly detection, reducing alert noise).
OpenTelemetry
An open source framework providing standards, APIs, and SDKs to collect and export observability data (traces, metrics, logs) in an agnostic way.
Core Web Vitals
Set of three metrics defined by Google to measure the real experience of a web page: loading (LCP (Largest Contentful Paint)), responsiveness (INP (In...
LCP (Largest Contentful Paint)
Time until the largest visible element of the page (image, video or text block) is rendered: it shows when the main content appears. Loading metric of...
INP (Interaction to Next Paint)
Latency of interactions (click, tap, key press) observed over the whole visit: the delay between the user's action and the next paint. The reported va...
CLS (Cumulative Layout Shift)
Measure of visual stability: the sum of unexpected layout shifts (a button moving just as you click, text pushed down by an ad). Unitless, computed ov...
FCP (First Contentful Paint)
Time until the first content (text, image, SVG) is rendered: the moment the user sees the page start loading. It is not a Core Web Vital, but it helps...
TTFB (Time to First Byte)
Time between the start of navigation and the arrival of the first byte of the response: it adds up redirects, DNS, TCP/TLS connection and server proce...
FID (First Input Delay)
Former responsiveness metric of the Core Web Vitals: the delay before the browser starts handling the first interaction (good ≤ 100 ms). It ignored la...
TBT (Total Blocking Time)
Lab metric (Lighthouse): the sum, between FCP (First Contentful Paint) and the end of loading, of the blocking part of each long task (over 50 ms) on ...
CrUX (Chrome UX Report)
Google's public dataset aggregating the Core Web Vitals measured from real Chrome users (at the 75th percentile, per origin and URL, over a rolling 28...
Lighthouse
Google's free audit tool, built into Chrome DevTools and PageSpeed Insights: it loads the page in a simulated environment and scores performance, acce...
