SigNoz is an open-source observability platform designed to collect, store, and visualize logs, metrics, and traces in a single interface. Built on OpenTelemetry, SigNoz enables correlated signals and unified dashboards, with ClickHouse serving as the log datastore.
Key Features
- Unified observability across logs, metrics, and traces
- OpenTelemetry-native ingestion with semantic conventions
- ClickHouse-backed log storage for fast queries
- DIY query builder, PromQL support, and flexible dashboards
- Alerts across signals with anomaly detection capabilities
- Tracing visuals including flamegraphs and detailed span views
Use Cases
- Instrumenting applications with OpenTelemetry to achieve end-to-end visibility across services
- Correlating logs, metrics, and traces to troubleshoot microservices and distributed systems
- Providing centralized observability for cloud-native environments with unified dashboards
Conclusion: SigNoz offers a single, OpenTelemetry-native platform to observe modern applications through correlated signals, scalable storage, and flexible visualization and alerting capabilities. It emphasizes openness, data correlation, and end-to-end debugging across logs, metrics, and traces.
