SigNoz
SigNoz is an open-source observability platform that collects logs, metrics, and traces into a single OpenTelemetry-native workspace.
SigNoz functions as an observability tool built on OpenTelemetry to monitor applications and infrastructure. It provides application performance monitoring (APM), log management, distributed tracing, and metrics collection. The platform uses a columnar database to allow users to search logs, trace spans, and visualize infrastructure performance in one interface. It supports AI agents by providing telemetry schemas and includes an AI assistant named Noz for investigating incidents and building dashboards. Teams use it to troubleshoot issues without switching between multiple tools, while maintaining portability through open standards.
