SigNoz

SigNoz is an open-source, self-hosted observability platform. It provides a unified observability platform that combines metrics, traces, and logs into a single interface to help teams monitor microservices architectures. The software is deployed as a server application and can be run using Docker, Kubernetes, or Linux, allowing teams to maintain full control over their data plane.

The platform focuses on reducing the need for fragmented monitoring stacks by correlating different telemetry signals in one place. It allows users to move between service charts, distributed traces, and infrastructure metrics without switching tools. This makes it suitable for teams managing complex distributed systems that require a centralized view of application performance, system health, and error rates across multiple services.

Key features

• Distributed tracing with flamegraphs and waterfall views to follow requests across services.
• Log management with a visual query builder for searching and aggregating logs.
• Infrastructure monitoring for Kubernetes clusters, pods, nodes, and host-level resources.
• Custom dashboards supporting PromQL and ClickHouse SQL for application and system metrics.
• LLM observability to trace RAG pipelines, prompts, tokens, and AI tool calls.
• Trace funnels to analyze request-flow drop-offs and systemic workflow issues.
• Native OpenTelemetry integration for standardized instrumentation and data ownership.
• Alerting system to notify teams of production issues based on telemetry data.

SigNoz is built on a columnar database designed for high-cardinality and high-volume observability workloads, which reduces resource requirements during ingestion compared to some traditional log management tools. It integrates with Prometheus and various language SDKs to ingest data. The architecture is intended for DevOps engineers and SREs who need to debug production issues faster by linking exceptions and logs directly to specific traces. It also includes an MCP server to bring telemetry into coding agents for incident investigation.

It serves as a comprehensive observability suite for organizations seeking an open-standard platform.
