Overview:
SigNoz is an open-source observability platform that provides logs, metrics, and traces in a single tool. It is designed as an alternative to commercial solutions like Datadog and New Relic. Built on OpenTelemetry for data collection, it helps developers and DevOps teams monitor application performance, troubleshoot issues, and centralize telemetry data. It uses ClickHouse as its underlying datastore for fast, scalable storage and querying of observability data.
Core Features:
Application Performance Monitoring (APM): Provides out-of-box charts for p99 latency, error rate, Apdex, and operations per second, along with monitoring for database and external calls.
Logs Management: Centralized log management with ClickHouse storage, enabling instant search via quick filters and a query builder. Users can also create charts and dashboards from log data.
Distributed Tracing: Powered by OpenTelemetry, allows tracking user requests across microservices with Flamegraphs and Gantt Charts for detailed breakdowns of request flows.
Metrics and Dashboards: Supports ingesting infrastructure or application metrics to create custom dashboards using panel types like pie charts, time-series, and bar charts, plus a metrics query builder.
LLM Observability: Monitors LLM applications by tracking calls, token usage, and performance to debug and optimize AI application behavior in production.
Alerts and Exceptions Monitoring: Alerts can be set on any telemetry signal with thresholds and anomaly detection; exceptions monitoring is automatic for Python, Java, Ruby, and JavaScript with stack trace visibility.
Use Cases:
Debugging microservices applications: Developers can use distributed tracing to identify performance bottlenecks by tracking user requests across services.
Centralizing logs for troubleshooting: Teams can aggregate and search through logs using quick filters and a query builder to debug issues faster.
Monitoring LLM applications in production: Engineers can track LLM calls, token usage, and performance to identify issues with prompts and responses.
Setting proactive alerts on telemetry data: DevOps teams can create thresholds and anomaly detection on logs, metrics, or traces to be notified of unusual application behavior.
Why It Matters:
SigNoz consolidates logs, metrics, and traces into one platform, reducing the need to stitch together multiple tools like Prometheus for metrics and Jaeger for traces. Its reliance on OpenTelemetry provides a vendor-neutral standard for data collection, and the use of ClickHouse supports efficient aggregate queries on high-cardinality data. The project is fully open-source, allowing self-hosting or use of its cloud service based on user preferences.
