Zipkin 指标采集

Zipkin 集成 Prometheus 监控

项目中引入 micrometer-prometheus 依赖，可实现 Zipkin 组件的指标采集

<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-registry-prometheus</artifactId>
</dependency>

采集指标如下：

# HELP zipkin_reporter_queue_bytes Total size of all encoded spans queued for reporting
# TYPE zipkin_reporter_queue_bytes gauge
zipkin_reporter_queue_bytes{application="app-test",} 0.0
# HELP zipkin_reporter_spans_dropped_total Spans dropped (failed to report)
# TYPE zipkin_reporter_spans_dropped_total counter
zipkin_reporter_spans_dropped_total{application="app-test",} 0.0
# HELP zipkin_reporter_messages_bytes_total Total bytes of messages reported
# TYPE zipkin_reporter_messages_bytes_total counter
zipkin_reporter_messages_bytes_total{application="app-test",} 841.0
# HELP zipkin_reporter_spans_total Spans reported
# TYPE zipkin_reporter_spans_total counter
zipkin_reporter_spans_total{application="app-test",} 2.0
# HELP zipkin_reporter_queue_spans Spans queued for reporting
# TYPE zipkin_reporter_queue_spans gauge
zipkin_reporter_queue_spans{application="app-test",} 0.0
# HELP zipkin_reporter_messages_total Messages reported (or attempted to be reported)
# TYPE zipkin_reporter_messages_total counter
