SigNoz is an observability platform for monitoring applications and investigating performance problems. It brings application metrics, distributed traces and logs together in one interface, allowing developers and operators to examine service behaviour without switching between independent monitoring systems.
The platform is built around OpenTelemetry and is designed for applications running across distributed infrastructure. It helps identify slow requests, failing services and unexpected changes in application performance.
SigNoz provides a graphical environment for investigating telemetry, examining individual requests and configuring dashboards. It is particularly useful when troubleshooting microservices, where understanding the interactions between application components is essential.
This is free and open source software.
Key Features
- Collect logs, metrics and distributed traces using OpenTelemetry instrumentation.
- Monitor application latency, request throughput and error rates.
- Display service-level performance statistics, including latency percentiles.
- Investigate individual distributed traces to identify slow operations.
- Visualise relationships and dependencies between instrumented services.
- Analyse database queries, external requests and individual application endpoints.
- Search and filter log records using structured attributes.
- Correlate log messages with related distributed traces.
- Investigate exceptions and errors recorded by supported application instrumentation.
- Create custom dashboards containing metrics and other telemetry visualisations.
- Configure alert rules through a graphical query builder.
- Send alerts through supported notification integrations and webhooks.
- Provide monitoring interfaces for infrastructure and application services.
- Support OpenTelemetry instrumentation across several programming languages and application frameworks.
