OpenTelemetry - Offener Standard für den Durchblick in Anwendungslandschaften

Um in verteilten Anwendungslandschaften den Überblick zu behalten, gibt es schon seit einiger Zeit unterschiedliche Ansätze um Daten wie Metriken, Traces und Logs zentralisiert zu analysieren. Die Uneinheitlichkeit machte es bislang aufwändig wirklich alle Komponenten einfach zu berücksichtigen. Im Jahr 2019 wurde unter dem Dach der Cloud Native Computing Foundation (CNCF) OpenTelemetry als herstellerneutrales, quelloffenes Ökosystem mit dem Ziel geschaffen die Erfassung und Übertragung von Telemetriedaten zu standardisieren.

In dieser Session werden die Spezifikation und deren Bestandteile kurz vorgestellt. Es wird gezeigt, wie eine Integration bei Java-Anwendungen und die Verknüpfung mit gängigen Bibliotheken (Drop-In Instrumentation) erfolgt. Zuletzt wird auf die Interaktion mit Cloud-Infrastruktur eingegangen, da OpenTelemetry sich insbesondere auf cloud-native Anwendungen fokussiert.

There’s no consolidation in the observability space. 3. Prometheus and Grafana are frequently used together.” https://radar.cncf.io/2020-09-observability https://www.cncf.io/blog/2020/09/11/cncf-end-user-technology-radar-observability-september-2020/
11. CLOUDLAND 2022 - OPENTELEMETRY © 2022, Amazon Web Services, Inc. or its affiliates. What is OpenTelemetry OpenTelemetry is a collection of tools, APIs, and SDKs. You can use it to instrument, generate, collect, and export telemetry data (metrics, logs, and traces) for analysis in order to understand your software's performance and behavior.

15. CLOUDLAND 2022 - OPENTELEMETRY © 2022, Amazon Web Services, Inc. or its affiliates. Tracing concepts in a nutshell • Span represents an operation within a transaction. Typically encapsulates: operation name, a start and finish timestamp, attributes (a list of key-value pairs), events, a parent span identifier, links to other spans, and a SpanContext. • Trace defined implicitly by its spans. A trace can be thought of as a directed acyclic graph (DAG) of spans where the edges between spans are defined as parent/child relationships. • SpanContext represents all the information that identifies Span in the Trace and MUST be propagated to child Spans and across process boundaries. A SpanContext contains the tracing identifiers and the options that are propagated from parent to child Spans. • Tracer is responsible for tracking the currently active span. https://github.com/open-telemetry/opentelemetry- specification/blob/main/specification/overview.md#tracing-signal

Collector Deployment • Agent: A Collector instance running with the application or on the same host as the application (e.g. binary, sidecar, or daemonset). • Gateway: One or more Collector instances running as a standalone service (e.g. container or deployment) typically per cluster, datacenter or region. Components • Receivers: How to get data into the Collector; these can be push or pull based • Processors: What to do with received data • Exporters: Where to send received data; these can be push or pull based • Pipelines: Enable the components V E N D O R - A G N O S T I C W A Y T O R E C E I V E , P R O C E S S A N D E X P O R T T E L E M E T R Y D A T A https://opentelemetry.io/docs/concepts/data-collection/
