go-trace

go-trace

Logging & tracing utilities for micro services.

Based on:

• go.uber.org/zap
• go.opencensus.io/trace

Tested to be compatible wih Datadog tracing.

Logging

The main idea is to unify logging and tracing, and insulate the app layer from the intricacies of tracing.

This repo provides a few wrappers around a zap.Logger:

• a logger factory based on zap logger, with a convenient builder to link logs to trace spans
• a logger builder, e.g. to initialize a root logger for your service
• a simple middleware to trace a http.Handler

Exporters

Various opencensus exporters.

• influxdb: export opencensus metrics to an influxdb sink
• amplitude (experimental): propagate trace event to the amplitude API

TODOs:

• [] opentelemetry/opentracing

Tracing

Simple utilities to instrument tracing inside apps.

Example Usage

Middleware

• log/middleware/LogRequests logs all requests from a http server, using the logger factory
• tracer.Middleware wraps the ochttp opencensus plugin in a more convenient middleware.
