JetBrains released Tracy, an open-source Kotlin and Java library that standardizes AI tracing with OpenTelemetry’s Generative AI semantics.
Per InfoWorld, Tracy captures structured spans for model calls, tool calls, and custom logic, including tokens, cost, and latency. It supports Kotlin 2.0+, Java 17+, integrates with OpenAI, Anthropic, and Gemini SDKs, works with OkHttp/Ktor, and exports to Langfuse and Weave.
This lines up with broader pressure to overhaul observability for AI workloads. Teams are rethinking data pipelines and on-call workflows to tame noisy, expensive signals (DevOps.com, HackerNoon). OpenTelemetry-compatible spans give you a portable schema instead of bespoke logs and ad-hoc dashboards.
AI features add opaque failure modes and variable costs; standardized traces make debugging and spend forecasting tractable.
OpenTelemetry compatibility reduces lock-in and lets existing observability stacks absorb AI signals with less glue code.
-
terminal
Instrument a staging service with Tracy around LLM and tool calls; export to Langfuse or Weave and verify spans include tokens, cost, inputs/outputs, and latency.
-
terminal
Measure overhead and attribute cardinality under load; compare Tracy’s token and cost metrics against provider billing for accuracy.
Legacy codebase integration strategies...
- 01.
Layer Tracy spans alongside existing OpenTelemetry instrumentation; check context propagation across OkHttp/Ktor and background jobs.
- 02.
Start with sampling and PII redaction; cap attribute sizes to protect collectors and control storage costs.
Fresh architecture paradigms...
- 01.
Adopt OpenTelemetry Generative AI semantics from day one using Tracy for all LLM, tool, and function spans.
- 02.
Define a minimal trace schema for prompts/outputs and choose Langfuse or Weave until your primary OTel backend natively supports these spans.
