Go语言可观测性架构：三大支柱融合

Go语言可观测性架构三大支柱融合1. 可观测性三大支柱可观测性包括指标Metrics、追踪Traces、日志Logs三个维度三者结合才能实现全面的系统监控。2. 统一架构package observability type Observability struct { tracer *otel.Tracer meter *prometheus.Meter logger *zap.Logger } func NewObservability(serviceName string) (*Observability, error) { tracer, err : otel.NewTracer(serviceName) if err ! nil { return nil, err } meter, err : prometheus.NewMeter(serviceName) if err ! nil { return nil, err } logger, err : zap.NewLogger() if err ! nil { return nil, err } return Observability{ tracer: tracer, meter: meter, logger: logger, }, nil } func (o *Observability) RecordRequest(ctx context.Context, req *Request) { ctx, span : o.tracer.StartSpan(ctx, handle_request) defer span.End() start : time.Now() o.logger.Info(request received, zap.String(method, req.Method), zap.String(path, req.Path), ) o.meter.RecordCounter(requests_total, method, req.Method, path, req.Path, ) duration : time.Since(start) span.SetAttributes( attribute.String(http.method, req.Method), attribute.String(http.path, req.Path), attribute.Int64(http.duration_ms, duration.Milliseconds()), ) o.meter.RecordHistogram(request_duration_seconds, method, req.Method, path, req.Path, float64(duration.Seconds()), ) }3. 总结可观测性三大支柱的融合可以提供全面的系统监控能力帮助快速定位和解决问题。
