第二十九章 springboot + zipkin + mysql

zipkin的数据存储可以存在4个地方:

内存(仅用于测试,数据不会持久化,zipkin-server关掉,数据就没有了)

这也是之前使用的mysql

可能是最熟悉的方式es
Cassandra

一、代码(基于第二十八章 springboot + zipkin(brave定制-AsyncHttpClient))


1、pom.xml

1
2io.zipkin.brave
3brave-mysql
43.9.0
5

2、ZipkinConfig添加如下

1@Bean 2 public MySQLStatementInterceptorManagementBean mySQLStatementInterceptorManagementBean(Brave brave) { 3return new MySQLStatementInterceptorManagementBean(brave.clientTracer()); 4 }

二、数据库


1、建库

自己创建库(eg.mytestdb)就好

2、建表

在mytestdb中执行zipkin准备好的脚本mysql.sql来创建三张表以及各个索引。

mysql.sql位置:https://github.com/openzipkin/zipkin/blob/master/zipkin-storage/mysql/src/main/resources/mysql.sql


或者直接将整个zipkin项目克隆下来,再进去看内容。


mysql.sql内容如下:


1 CREATE TABLE IF NOT EXISTS zipkin_spans (2 `trace_id` BIGINT NOT NULL,3 `id` BIGINT NOT NULL,4 `name` VARCHAR(255) NOT NULL,5 `parent_id` BIGINT,6 `debug` BIT(1),7 `start_ts` BIGINT COMMENT 'Span.timestamp(): epoch micros used for endTs query and to implement TTL',8 `duration` BIGINT COMMENT 'Span.duration(): micros used for minDuration and maxDuration query'
9 ) ENGINE=InnoDB ROW_FORMAT=COMPRESSED; 10
11 ALTER TABLE zipkin_spans ADD UNIQUE KEY(`trace_id`, `id`) COMMENT 'ignore insert on duplicate'; 12 ALTER TABLE zipkin_spans ADD INDEX(`trace_id`, `id`) COMMENT 'for joining with zipkin_annotations'; 13 ALTER TABLE zipkin_spans ADD INDEX(`trace_id`) COMMENT 'for getTracesByIds'; 14 ALTER TABLE zipkin_spans ADD INDEX(`name`) COMMENT 'for getTraces and getSpanNames'; 15 ALTER TABLE zipkin_spans ADD INDEX(`start_ts`) COMMENT 'for getTraces ordering and range'; 16
17 CREATE TABLE IF NOT EXISTS zipkin_annotations ( 18 `trace_id` BIGINT NOT NULL COMMENT 'coincides with zipkin_spans.trace_id', 19 `span_id` BIGINT NOT NULL COMMENT 'coincides with zipkin_spans.id', 20 `a_key` VARCHAR(255) NOT NULL COMMENT 'BinaryAnnotation.key or Annotation.value if type == -1', 21 `a_value` BLOB COMMENT 'BinaryAnnotation.value(), which must be smaller than 64KB', 22 `a_type` INT NOT NULL COMMENT 'BinaryAnnotation.type() or -1 if Annotation', 23 `a_timestamp` BIGINT COMMENT 'Used to implement TTL; Annotation.timestamp or zipkin_spans.timestamp', 24 `endpoint_ipv4` INT COMMENT 'Null when Binary/Annotation.endpoint is null', 25 `endpoint_ipv6` BINARY(16) COMMENT 'Null when Binary/Annotation.endpoint is null, or no IPv6 address', 26 `endpoint_port` SMALLINT COMMENT 'Null when Binary/Annotation.endpoint is null', 27 `endpoint_service_name` VARCHAR(255) COMMENT 'Null when Binary/Annotation.endpoint is null'
28 ) ENGINE=InnoDB ROW_FORMAT=COMPRESSED; 29
30 ALTER TABLE zipkin_annotations ADD UNIQUE KEY(`trace_id`, `span_id`, `a_key`, `a_timestamp`) COMMENT 'Ignore insert on duplicate'; 31 ALTER TABLE zipkin_annotations ADD INDEX(`trace_id`, `span_id`) COMMENT 'for joining with zipkin_spans'; 32 ALTER TABLE zipkin_annotations ADD INDEX(`trace_id`) COMMENT 'for getTraces/ByIds'; 33 ALTER TABLE zipkin_annotations ADD INDEX(`endpoint_service_name`) COMMENT 'for getTraces and getServiceNames'; 34 ALTER TABLE zipkin_annotations ADD INDEX(`a_type`) COMMENT 'for getTraces'; 35 ALTER TABLE zipkin_annotations ADD INDEX(`a_key`) COMMENT 'for getTraces'; 36
37 CREATE TABLE IF NOT EXISTS zipkin_dependencies ( 38 `day` DATE NOT NULL, 39 `parent` VARCHAR(255) NOT NULL, 40 `child` VARCHAR(255) NOT NULL, 41 `call_count` BIGINT
42 ) ENGINE=InnoDB ROW_FORMAT=COMPRESSED; 43
44 ALTER TABLE zipkin_dependencies ADD UNIQUE KEY(`day`, `parent`, `child`);View Code

执行脚本之后,数据库出现三张表,如下:


三、启动命令

STORAGE_TYPE=mysql MYSQL_HOST=192.192.192.192 MYSQL_TCP_PORT=3306 MYSQL_DB=mytestdb MYSQL_USER=root MYSQL_PASS=123456 nohup java -jar zipkin-server-1.5.1-exec.jar &

STORAGE_TYPE:存储类型,这里是mysql
MYSQL_HOST和MYSQL_TCP_PORT:创建connection
MYSQL_USER和MYSQL_PASS:用户名和密码

四、测试


启动4个service,然后swagger测试,最后查看zipkin和数据库表即可。
