LLM Observability and Tracing in Production: Comparing Langfuse, Arize Phoenix, LangSmith, and OpenLLMetry
LLM Observability and Tracing in Production: Comparing Langfuse, Arize Phoenix, LangSmith, and OpenLLMetry Moving language models from single-turn prompt wrappers into multi-agent architectures, recursive Retrieval-Augmented Generation (RAG) graphs, and autonomous tool-calling loops fundamentally changes system dynamics. LLM applications behave as distributed state machines where failure modes are rarely deterministic. Latency spikes can stem from vector store indexing bottlenecks, context wind

LLM Observability and Tracing in Production: Comparing Langfuse, Arize Phoenix, OpenInference, and Helicone Architecture, OpenTelemetry GenAI Semantic Conventions, Sampling Strategies, and Ingestion Economics
Monitoring distributed software architectures has traditionally relied on metrics, logs, and distributed traces centered around deterministic HTTP requests and database queries. As production architectures shift toward autonomous agents, multi-step retrieval-augmented generation (RAG) pipelines, and chain-of-thought inference loops, standard application performance monitoring (APM) tools struggle with the non-deterministic execution paths, large token payloads, and variable latencies inherent to

Tracing multi-step LLM pipelines, autonomous agent graphs, and retrieval-augmented generation (RAG) systems in production introduces telemetry challenges that traditional Application Performance Monitoring (APM) tools cannot address out of the box. While standard microservices rely on CPU utilization, HTTP status codes, and network latency percentiles, LLM workflows require deep inspection into non-deterministic text generation, nested execution graphs, prompt token counts, retrieved context rel

LLM Observability in Production: OpenTelemetry GenAI Semantic Conventions vs. OpenInference, Distributed Trace Propagation Across Multi-Agent Graphs, and High-Throughput Sampling Economics
Production large language model (LLM) architectures have transitioned from isolated completion endpoints to complex, distributed directed acyclic graphs (DAGs). Modern AI systems incorporate multi-agent orchestration, iterative tool execution, vector retrieval pipelines, and speculative decoding loops. Operating these workloads at enterprise scale exposes critical observability gaps that traditional application performance monitoring (APM) tools cannot address. Standard request-response APM metr

LLM Observability in Production: OpenTelemetry Semantic Conventions, Distributed Tracing, and Latency Profiling Deploying large language models into production introduces failure modes that traditional application performance monitoring (APM) tools were never designed to diagnose. Standard web services fail with discrete HTTP error codes, predictable database timeouts, or memory leaks. In contrast, LLM applications fail through silent semantic drift, hallucinated tool parameters, unbounded prom
