AI Observability & Evaluation

Prefect is a workflow orchestration framework for building resilient data pipelines in Python.

The OpenTelemetry .NET Client

Polly is a .NET resilience and transient-fault-handling library that allows developers to express policies such as Retry, Circuit Breaker, Timeout, Bulkhead Isolation, and Fallback in a fluent and thread-safe manner. From version 6.0.1, Polly targets .NET Standard 1.1 and 2.0+.

Datadog Python APM Client

An AI Gateway, registry, and proxy that sits in front of any MCP, A2A, or REST/gRPC APIs, exposing a unified endpoint with centralized discovery, guardrails and management. Optimizes Agent & Tool calling, and supports plugins.

eBPF-based Networking, Security, and Observability

Grafana Mimir provides horizontally scalable, highly available, multi-tenant, long-term storage for Prometheus.

LangSmith Client SDK Implementations

The open source AI engineering platform for agents, LLMs, and ML models. MLflow enables teams of all sizes to debug, evaluate, monitor, and optimize production-quality AI applications while controlling costs and managing access to models and data.

OpenTelemetry Collector

AI observability platform for production LLM and agent systems.

Automate Kubernetes observability with Dynatrace

The open-source observability database. One columnar engine for metrics, logs, and traces, on object storage.

Send usage data from your web app or site to PostHog, with autocapture.

SigNoz is an open-source, OpenTelemetry-native observability platform for your team and their AI agents. Get logs, metrics, and traces in one tool with features like APM, distributed tracing, log management, infra monitoring, etc. Combined with SigNoz MCP and a native AI teammate (in SigNoz Cloud) it helps you build more resilient apps.

Lambda durable functions SDK

The dbt-native data observability solution for data & analytics engineers. Monitor your data pipelines in minutes. Available as self-hosted or cloud service with premium features.

OpenTelemetry Collector distribution with programmable pipelines

The Grafana Faro Web SDK, part of the Grafana Faro project, is a highly configurable web SDK for real user monitoring (RUM) that instruments browser frontend applications to capture observability signals. Frontend telemetry can then be correlated with backend and infrastructure data for full-stack observability.

Continuous Profiling Platform. Debug performance issues down to a single line of code

The platform for LLM evaluations and AI agent testing

Oxidizer is a platform for Rust service development which bridges the gaps in the crate ecosystem to deliver a turn-key solution to enable the efficient creation of high-scale high-availability and high-performance services in Rust.

eBPF distributed networking observability tool for Kubernetes

The fastest path to AI-powered full stack observability, even for lean teams.

NGINX Agent provides an administrative entry point to remotely manage, configure and collect metrics and events from NGINX instances

This repository contains set of components extending functionality of the OpenTelemetry .NET SDK. Instrumentation libraries, exporters, and other components can find their home here.
