Opentelemetry Specification
Acest depozit conține specificațiile pentru un standard de date de observabilitate și un framework de instrumentare a telemetriei. Definește protocoale unificate pentru modul în care datele de telemetrie sunt instrumentate, propagate și formatate pentru a asigura interoperabilitatea între sistemele distribuite.
Specificația oferă o abordare vendor-neutral pentru observabilitate, permițând exportarea datelor de telemetrie către diverse backend-uri fără a fi blocat la un singur furnizor sau a necesita modificări ale codului sursă al aplicației. Stabilește un protocol consistent pentru capturarea fluxurilor de cereri peste limitele serviciilor pentru a corela activitatea și a analiza performanța sistemului.
Framework-ul acoperă o suprafață largă de capabilități de monitorizare, inclusiv colectarea metricilor de sistem, agregarea log-urilor aplicației și capturarea trace-urilor distribuite. Definește metode atât pentru instrumentarea automată, cât și pentru cea manuală și specifică mecanismele pentru propagarea contextului și rutarea semnalelor de telemetrie prin pipeline-uri de date.
Features
- Cloud Native Observability - Implements a vendor-neutral standard for collecting metrics, logs, and traces within cloud-native and distributed environments.
- Unified Observability Data Models - Defines a consistent data model that unifies metrics, logs, and traces as timestamped wide events.
- Distributed Tracing - Specifies the protocols for recording and visualizing the lifecycle of requests as they traverse distributed service architectures.
- Tracing Context Propagation - Implements mechanisms for injecting and extracting distributed tracing headers across network boundaries to maintain request correlation.
- Application Performance Monitoring - Provides a standardized approach for tracking runtime errors and performance bottlenecks in distributed software.
- Instrumentation APIs - Provides standardized interfaces for adding both manual and automatic observability markers to application code.
- Distributed Tracing - Defines methods for tracking requests across distributed systems using unique identifiers to analyze performance and execution flow.
- Vendor-Neutral Observability Interfaces - Provides standardized APIs that decouple application code from specific monitoring providers to prevent vendor lock-in.
- Zero-Code Instrumentation - Enables monitoring agents to be attached for telemetry collection without requiring modifications to application source code.
- Telemetry Data Pipelines - Provides a configurable layer for ingesting, parsing, and transforming raw observability data before export.
- OTLP Telemetry Routing - Routes observability data through processors and filters using OpenTelemetry standards.
- Distributed Log Aggregation - Collects and unifies timestamped event records from multiple distributed services for centralized monitoring.
- Telemetry Exporters - Pushes internal performance metrics and logs to various third-party observability platforms using a neutral standard.
- Instrumentation Libraries - Supplies libraries for adding custom tracking and tracing directly into application code via manual instrumentation.
- System Metrics Collection - Records system-level performance metrics over time to monitor resource usage and software health.
- Tracing And Profiling - Framework for cloud-native observability.
