Tools/OpenTelemetry
OpenTelemetry
Vendor-neutral standard (CNCF) for instrumenting applications with traces, metrics, and logs — a single SDK/collector pipeline that exports to any compatible backend (Grafana, Elasticsearch/OpenSearch, Datadog, etc.), instead of hand-rolling per-vendor instrumentation. The common instrumentation layer underneath most modern observability stacks, including LLM-specific tracing tools like Langfuse.
