**APIs profiled:** 3

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.
