  description: The Jaeger Query API (api_v3) exposes services, operations, trace search, single-trace lookup,
    and inter-service dependency graphs over HTTP (port 16686) and gRPC (port 16685). It is the
    OpenTelemetry-aligned successor to the legacy /api/* HTTP endpoints and powers the Jaeger UI.

  description: The Jaeger Collector ingests spans over multiple protocols — native Jaeger api_v2
    (gRPC 14250, HTTP 14268), OTLP (gRPC 4317, HTTP 4318), and Zipkin (HTTP 9411) — and writes them
    to the configured storage backend (Cassandra, OpenSearch, Elasticsearch, ClickHouse, Kafka, or
    Badger). In Jaeger v2 the Collector is a customized OpenTelemetry Collector distribution.

  description: Remote sampling configuration API. Tracer SDKs poll the Sampling Manager (HTTP port
    5778, gRPC port 5779) to retrieve the active per-service sampling strategy — probabilistic,
    rate-limiting, or per-operation. Backed by a static strategies file or by Jaeger's adaptive
    sampling subsystem.

- type: Features
  data:
  - Distributed tracing platform — CNCF graduated project, originated at Uber, now community maintained
  - Jaeger v2 is built on the OpenTelemetry Collector — first-class OTLP support on ports 4317/gRPC and 4318/HTTP
  - Native Jaeger api_v2 ingest over gRPC (14250) and HTTP (14268) for legacy SDKs
  - Zipkin v1/v2 compatibility on port 9411 for migration from Zipkin
  - Query API v3 exposes services, operations, trace search, single-trace lookup, and dependency graphs over HTTP (16686) and gRPC (16685)
  - Remote sampling — probabilistic, rate-limiting, per-operation, and adaptive strategies served via SamplingManager on port 5778/5779
  - Pluggable storage — Cassandra, OpenSearch, Elasticsearch, ClickHouse, Kafka (buffered), Badger (embedded)
  - Service Performance Monitoring (SPM) view — RED metrics derived from spans
  - Service dependency graph computed offline via the spark-dependencies job
  - Kubernetes-native deployment via the Jaeger Operator and official Helm charts
  - All-in-one binary for local development with in-memory storage
  - React UI bundled in the Query service plus a Grafana datasource plugin and VS Code extension
  - SDKs deprecated in favor of OpenTelemetry SDKs (Go, Python, Java, JS, .NET, C++, Ruby, PHP)
  - Apache 2.0 licensed; governance via GOVERNANCE.md and MAINTAINERS.md

description: Jaeger is an open-source, end-to-end distributed tracing platform for monitoring and
  troubleshooting transactions in complex distributed systems. Originally built and open-sourced
  by Uber Technologies in 2017, Jaeger was donated to the Cloud Native Computing Foundation, became
  an incubating project in 2017, and graduated in 2019. Jaeger v2, released in November 2024, is a
  customized distribution of the OpenTelemetry Collector and is the OTLP-native generation of the
  platform. It exposes three primary APIs — the Query API (read), the Collector API (span ingest),
  and the Sampling Manager API (remote sampling configuration) — across HTTP and gRPC, supports six
  pluggable storage backends, and ships with a Kubernetes Operator, Helm charts, a React UI, and a
  Grafana plugin.
