Instrument Haystack

Recipe — instrument a Haystack pipeline using manual trace upload.

Private preview. This surface is not yet generally available. Adapters live in the Python SDK today and the rendering / configuration UX is under iteration. Contact [email protected] to request access to the private preview.

When to use: Haystack pipeline (RAG, search) and you want traces in Stratix.

The Stratix SDK does not currently ship a dedicated Haystack adapter. Use manual trace upload after each pipeline run.

import json, uuid
from pathlib import Path
from layerlens import Stratix
client = Stratix()

# Run your Haystack pipeline
result = pipeline.run({"text_embedder": {"text": query}, "prompt_builder": {"query": query}})

# Build a trace record (data is flexible Dict[str, Any])
trace_record = {
 "id": str(uuid.uuid4()),
 "input": query,
 "output": result["llm"]["replies"][0] if "llm" in result else None,
 "data": {
 "haystack_pipeline_outputs": result,
 },
}

Path("haystack_trace.jsonl").write_text(json.dumps(trace_record))
client.traces.upload("haystack_trace.jsonl")
