链路追踪介绍

链路追踪主要用于分布式系统，服务出现级联调用，能够提供调用的时间且能结算出网络延迟时间——>将服务还原成链路 

链路数据模型有三个点

Trace：一个完整的链路，用的是我们的雪花算法

Span：一次调用完整的过程（开始时间和结束时间）

parentId：父节点id

 zipkin整合mysql和mq

1.创建数据库

CREATE TABLE IF NOT EXISTS zipkin_spans (
  `trace_id_high` BIGINT NOT NULL DEFAULT 0 COMMENT 'If non zero, this means the trace uses 128 bit traceIds instead of 64 bit',
  `trace_id` BIGINT NOT NULL,
  `id` BIGINT NOT NULL,
  `name` VARCHAR(255) NOT NULL,
  `parent_id` BIGINT,
  `debug` BIT(1),
  `start_ts` BIGINT COMMENT 'Span.timestamp(): epoch micros used for endTs query and to implement TTL',
  `duration` BIGINT COMMENT 'Span.duration(): micros used for minDuration and maxDuration query'
) ENGINE=InnoDB ROW_FORMAT=COMPRESSED CHARACTER SET=utf8 COLLATE utf8_general_ci;
 
ALTER TABLE zipkin_spans ADD UNIQUE KEY(`trace_id_high`, `trace_id`, `id`) COMMENT 'ignore insert on duplicate';
ALTER TABLE zipkin_spans ADD INDEX(`trace_id_high`, `trace_id`, `id`) COMMENT 'for joining with zipkin_annotations';
ALTER TABLE zipkin_spans ADD INDEX(`trace_id_high`, `trace_id`) COMMENT 'for getTracesByIds';
ALTER TABLE zipkin_spans ADD INDEX(`name`) COMMENT 'for getTraces and getSpanNames';
ALTER TABLE zipkin_spans ADD INDEX(`start_ts`) COMMENT 'for getTraces ordering and range';
 
CREATE TABLE IF NOT EXISTS zipkin_annotations (
  `trace_id_high` BIGINT NOT NULL DEFAULT 0 COMMENT 'If non zero, this means the trace uses 128 bit traceIds instead of 64 bit',
  `trace_id` BIGINT NOT NULL COMMENT 'coincides with zipkin_spans.trace_id',
  `span_id` BIGINT NOT NULL COMMENT 'coincides with zipkin_spans.id',
  `a_key` VARCHAR(255) NOT NULL COMMENT 'BinaryAnnotation.key or Annotation.value if type == -1',
  `a_value` BLOB COMMENT 'BinaryAnnotation.value(), which must be smaller than 64KB',
  `a_type` INT NOT NULL COMMENT 'BinaryAnnotation.type() or -1 if Annotation',
  `a_timestamp` BIGINT COMMENT 'Used to implement TTL; Annotation.timestamp or zipkin_spans.timestamp',
  `endpoint_ipv4` INT COMMENT 'Null when Binary/Annotation.endpoint is null',
  `endpoint_ipv6` BINARY(16) COMMENT 'Null when Binary/Annotation.endpoint is null, or no IPv6 address',
  `endpoint_port` SMALLINT COMMENT 'Null when Binary/Annotation.endpoint is null',
  `endpoint_service_name` VARCHAR(255) COMMENT 'Null when Binary/Annotation.endpoint is null'
) ENGINE=InnoDB ROW_FORMAT=COMPRESSED CHARACTER SET=utf8 COLLATE utf8_general_ci;
 
ALTER TABLE zipkin_annotations ADD UNIQUE KEY(`trace_id_high`, `trace_id`, `span_id`, `a_key`, `a_timestamp`) COMMENT 'Ignore insert on duplicate';
ALTER TABLE zipkin_annotations ADD INDEX(`trace_id_high`, `trace_id`, `span_id`) COMMENT 'for joining with zipkin_spans';
ALTER TABLE zipkin_annotations ADD INDEX(`trace_id_high`, `trace_id`) COMMENT 'for getTraces/ByIds';
ALTER TABLE zipkin_annotations ADD INDEX(`endpoint_service_name`) COMMENT 'for getTraces and getServiceNames';
ALTER TABLE zipkin_annotations ADD INDEX(`a_type`) COMMENT 'for getTraces';
ALTER TABLE zipkin_annotations ADD INDEX(`a_key`) COMMENT 'for getTraces';
 
CREATE TABLE IF NOT EXISTS zipkin_dependencies (
  `day` DATE NOT NULL,
  `parent` VARCHAR(255) NOT NULL,
  `child` VARCHAR(255) NOT NULL,
  `error_count` BIGINT,
  `call_count` BIGINT
) ENGINE=InnoDB ROW_FORMAT=COMPRESSED CHARACTER SET=utf8 COLLATE utf8_general_ci;
 
ALTER TABLE zipkin_dependencies ADD UNIQUE KEY(`day`, `parent`, `child`);

2.开启运行java -jar xxx.jar并且整合mysql

我们通过客户端——>服务器server9411——>然后server将链路信息存储入数据库中，防止zipkin宕机后丢失内存中信息

java -jar zipkin-server-2.23.16-exec.jar --STORAGE_TYPE=mysql --MYSQL_HOST=82.157.198.247 --MYSQL_TCP_PORT=3306 --MYSQL_USER=root --MYSQL_PASS=123 --MYSQL_DB=zipkin

配置文件 

 zipkin:
    base-url: http://localhost:9411/ #zipkin服务端地址
    sender:
      type: rabbit #数据传输的方式
  sleuth:
    sampler:
      probability: 1.0 #数据收集百分比
  rabbitmq:
    host: 82.157.198.247
    port: 5672
    username: guest
    password: guest
    virtual-host: /
    listener:
      direct:
        retry:
          enabled: true
          max-attempts: 5
          initial-interval: 5000

访问server 

 发现链路信息在mysql中

 

导入mq也是一样的思路，利用mq实现异步的功能，当客户端传入信息，服务器server进行接收这个步骤是异步，如果没有消息队列，那么client——server——mysql这系列是同步的

java -jar zipkin-server-2.19.2-exec.jar --STORAGE_TYPE=mysql --MYSQL_HOST=82.157.198.247 --MYSQL_TCP_PORT=3306 --MYSQL_USER=root --MYSQL_PASS=123 --MYSQL_DB=zipkin --RABBIT_ADDRESSES=82.157.198.247:5672 --RABBIT_USER=guest --RABBIT_PASSWORD=guest --RABBIT_VIRTUAL_HOST=/
