Telemere

关于

Telemere is a next-generation observability library for the Clojure ecosystem that streamlines how developers handle application logs, traces, and metrics. It replaces traditional string-based logging with a structured data pipeline, allowing for sophisticated filtering, sampling, and integration with modern observability stacks like OpenTelemetry and SLF4J. Whether you need to track nested function execution with traces, monitor performance through spies, or manage complex log routing via async handlers, Telemere provides a consistent, high-performance interface that works across both JVM and browser environments with zero-configuration defaults.

主要功能

• Unified API for structured logging, distributed tracing, and performance monitoring
• Advanced runtime filtering by namespace, level, ID, and sampling rate
• Deep interoperability with OpenTelemetry, SLF4J, and tools.logging
• Support for both synchronous and asynchronous handler dispatch with buffering
• 2 GitHub stars
• Compile-time signal elision to ensure zero runtime cost for disabled logs

使用场景

• Implementing structured observability in production environments with high-performance requirements
• Debugging complex, nested function calls to visualize parent-child execution relationships
• Capturing and analyzing application performance metrics without manual instrumentation
