Metriken, Logs, Traces - Observability mit Open Source

Metriken, Logs, Traces - Observability mit Open Source

Um in verteilten Anwendungslandschaften den Überblick zu behalten, sollten Metriken, Logs und Traces genutzt werden. Doch eine Umfrage der Cloud Native Computing Foundation (CNCF) zeigt, dass dafür diverse Produkte genutzt werden. Wie kann man Observability vereinheitlichen und sowohl neue cloud-native als auch bestehende Anwendungen zusammenbringen?In dieser Session wird OpenTelemetry vorgestellt - ein herstellerneutrales, quelloffenes Ökosystem mit dem sich Telemetriedaten standardisiert erfassen und übertragen lassen. Es wird gezeigt, wie eine Anwendungsintegration und Verknüpfung mit gängigen Bibliotheken erfolgt. Zuletzt wird darauf eingegangen wie die AWS Distribution für OpenTelemetry (ADOT) die Integration mit AWS Monitoring and Observability Services wie Amazon CloudWatch und AWS X-Ray vereinfacht.

OpenTelemetry roadmap I N S T R U M E N T A T I O N A N D C O L L E C T I O N Tracing API: stable SDK: stable Protocol: stable • Specification is stable • Covered by long-term support • Specification is still extensible, but only in a backwards compatible manner • OpenTelemetry clients are versioned to v1.0 once their tracing implementation is complete Metrics (Preview) API: stable SDK: feature-freeze Protocol: stable • Currently under active development, the data model is stable. • Collector support for Prometheus is under development, in collaboration with the Prometheus community • Metric API and SDK specification is currently being prototyped in Java, .NET, and Python Logs API: draft SDK: draft Protocol: beta • Currently under active development • Log processing for many data formats has been added to the Collector. • Log appenders are in development for many languages. • A logging SDK is currently under development. • An OpenTelemetry logging API is not currently under development. https://opentelemetry.io/status/

    rights reserved. Tracing concepts • 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

OpenTelemetry 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/
