Structured logs are the observability pillar that uniquely models your apps and services. They capture the detailed, domain-specific events you need to debug tough problems, and they're perfect for monitoring and analyzing system behavior in real time. Seq is built from the ground up for modern structured logging. Events are captured as fully-structured JSON data, and Seq's query language makes it natural to search and manipulate them without awkward parsing or format handling. Seq accepts logs via HTTP, OpenTelemetry/OTLP, custom inputs, and the seqcli command-line client, with plug-ins or integrations available for .NET, Java, Node.js, Python, Ruby, Go, Docker, message queues, and many other technologies.
Seq is a powerful tool designed to help development teams capture, search, and visualize structured log events efficiently. As a self-hosted server, Seq is specifically built for analyzing and alerting based on structured logs and traces, making it an essential component of modern observability practices.
Key features of Seq include its ability to handle fully-structured JSON data, supported by a dedicated query language that simplifies searching without the need for complex parsing. It accepts logs through various channels such as HTTP, OpenTelemetry/OTLP, custom inputs, and the seqcli command-line client, with plugins available for multiple technologies like .NET, Java, and Node.js.
The platform offers robust search and filtering capabilities, enabling developers to quickly drill down into events using familiar techniques. For deeper insights, Seq provides SQL-style log analysis with time-slicing, allowing users to create charts and dashboards to track metrics such as error rates and latencies. Additionally, Seq supports tracing to provide visibility into complex operations, helping identify performance bottlenecks.
