Introduction
OpenTelemetry 1.10, released on September 12, 2022, continues to evolve as the unified standard for observability in cloud-native applications. This release improves SDK capabilities, enhances collector features, and delivers better Kubernetes integration for comprehensive telemetry collection.
In practice, this release is most relevant when you’re running Kubernetes workloads at scale and your observability stack has to keep up—high-cardinality metrics, noisy alerts, and dashboards that need to stay responsive during incidents.
SDK Improvements
- Language support expansion includes more stable SDKs for Go, Java, .NET, Python, JavaScript, and Ruby.
- Instrumentation libraries provide automatic tracing for popular frameworks and libraries.
- Auto-instrumentation enables observability without code changes for supported languages.
- Custom instrumentation APIs enable fine-grained control over what gets traced and measured.
Collector Enhancements
- Processors expansion enables more data transformation, filtering, and batching capabilities.
- Exporters improvements support integration with major observability backends.
- Receivers enhancements support multiple protocols (OTLP, Jaeger, Zipkin, Prometheus) for data ingestion.
- Performance optimizations reduce resource usage and improve throughput.
Kubernetes Integration
- Operator support enables automatic instrumentation of Kubernetes workloads with sidecar injection.
- Service mesh integration provides automatic tracing for Istio, Linkerd, and other service meshes.
- CNI integration enables network-level observability with eBPF-based tracing.
- Helm charts simplify deployment of OpenTelemetry collectors in Kubernetes clusters.
Unified Observability
- Tracing API provides a vendor-neutral interface for distributed tracing across microservices.
- Metrics API enables consistent metric collection with support for multiple metric types.
- Logging API (beta) establishes foundations for structured logging with correlation to traces and metrics.
- Context propagation enables seamless trace correlation across service boundaries and languages.
