Functions ¶
Types ¶
type Option ¶ added in v0.2.0
type Option func(opts *jaegerTracerOptions)
func WithBufferFlushInterval ¶ added in v0.2.0
WithBufferFlushInterval 强制清空、推送队列时间，对于流量不高的程序，队列可能长时间不能满，那么设置这个时间，超时可以自动推送一次。 对于高并发的情况，一般队列很快就会满的，满了后也会自动推送。默认为1秒
func WithCollectorEndpoint ¶ added in v0.2.0
WithCollectorEndpoint 设置 api (链路追踪数据直接上报 collector 组件) 用 Collector 就不用 agent 了
func WithReporterLogSpans ¶ added in v0.2.0
WithReporterLogSpans 设置 是否把 Log 也推送，span 中可以携带一些日志信息
func WithReporterQueueSize ¶ added in v0.2.0
WithReporterQueueSize 设置 设置队列大小，存储采样的 span 信息，队列满了后一次性发送到 jaeger 后端；defaultQueueSize 默认为 100；
func WithSamplerParam ¶ added in v0.2.0
WithSamplerParam 设置 采样率 0 - 1
func WithSamplerType ¶ added in v0.2.0
WithSamplerType 设置 采样方式 "const" 0或1 采样器始终对所有 tracer 做出相同的决定；要么全部采样，要么全部不采样 "probabilistic" 0.0~1.0 采样器做出随机采样决策，Param 为采样概率 "ratelimiting" N 采样器一定的恒定速率对tracer进行采样，Param=2.0，则限制每秒采集2条 "remote" 无 采样器请咨询Jaeger代理以获取在当前服务中使用的适当采样策略。
