skywalking 链路追踪组件使用
之前链路追踪的时候简单的有sleuth， 可以实现每个请求加一个traceId 和 spanId。其只是简单的对请求链路进行追踪，也基于slf4j的MDC 实现了日志增加输出链路信息，排错误的时候可以看到一些路由信息。
skywalking 比较全面，基于javaagent 探针技术，可以监测的信息比较多，比如链路信息、实例信息、数据库、vm、k8s 等都支持。并且也实现了日志采集以及日志分析。 简单研究下其使用。

1. 下载解压
我下载的版本是apache-skywalking-apm-bin-es7， 下载解压后目录如下：
2. 修改配置
修改存储采用mysql， 在自己的mysql 服务器上创建swtest 数据库。
修改%skywalking%/config/application.yml 配置文件。 修改数据源采用mysql: 大概112 行左右， 修改默认数据源采用mysql
storage:
selector: ${SW_STORAGE:mysql}
修改172 行左右mysql 相关配置(主要是账号密码相关)
mysql:
properties:
jdbcUrl: ${SW_JDBC_URL:"jdbc:mysql://localhost:3306/swtest"}
dataSource.user: ${SW_DATA_SOURCE_USER:root}
dataSource.password: ${SW_DATA_SOURCE_PASSWORD:123456}
dataSource.cachePrepStmts: ${SW_DATA_SOURCE_CACHE_PREP_STMTS:true}
dataSource.prepStmtCacheSize: ${SW_DATA_SOURCE_PREP_STMT_CACHE_SQL_SIZE:250}
dataSource.prepStmtCacheSqlLimit: ${SW_DATA_SOURCE_PREP_STMT_CACHE_SQL_LIMIT:2048}
dataSource.useServerPrepStmts: ${SW_DATA_SOURCE_USE_SERVER_PREP_STMTS:true}
metadataQueryMaxSize: ${SW_STORAGE_MYSQL_QUERY_MAX_SIZE:5000}
maxSizeOfArrayColumn: ${SW_STORAGE_MAX_SIZE_OF_ARRAY_COLUMN:20}
numOfSearchableValuesPerTag: ${SW_STORAGE_NUM_OF_SEARCHABLE_VALUES_PER_TAG:2}
3. 启动应用
%skywalking%/bin/startup.bat 启动应用
点击后可以看到启动两个窗口，一个Collector， 一个Webapp
1. Collector
2. Webapp 相关jar 包以及配置在%skywalking%/webapp 目录下面， 其中的配置可以用于修改web 服务启动的端口相关信息
访问8080 端口测试如下:
4. 应用程序接入sky
应用程序接入的时候是通过javaagent 代理的时候接入的。
(1) 网关服务接入
-javaagent:D:\study\skywalking\apache-skywalking-apm-bin-es7\agent\skywalking-agent.jar -Dskywalking.agent.service_name=gateway -Dskywalking.collector.backend_service=127.0.0.1:11800
-javaagent：指定skywalking中的agent中的skywalking-agent.jar的路径
-Dskywalking.agent.service_name：指定在skywalking中的服务名称，一般是微服务的spring.application.name
-Dskywalking.collector.backend_service：指定oap服务绑定的地址，我这里是本地，并且oap服务默认的端口是11800，因此只需要配置为127.0.0.1:11800
(2) producer 服务接入
-javaagent:D:\study\skywalking\apache-skywalking-apm-bin-es7\agent\skywalking-agent.jar -Dskywalking.agent.service_name=sky-producer -Dskywalking.collector.backend_service=127.0.0.1:11800
(3) consumer 接入
-javaagent:D:\study\skywalking\apache-skywalking-apm-bin-es7\agent\skywalking-agent.jar -Dskywalking.agent.service_name=sky-producer -Dskywalking.collector.backend_service=127.0.0.1:11800
5. 启动后访问后端一些请求查看sky
(1) 查看拓扑图
(2) 追踪： 可以看到一些请求的链路信息
(3) 另外sky 也能追踪一些Feign 接口以及一些mysql 查询相关，可以说非常的方便。 比如自己再加入两个服务，一个payment 服务是调用数据库查询，另一个通过OpenFeign 调用该接口，查看追踪信息如下
继续点击mysql那一条记录， 可以看到打出相关的mysql 执行的服务器以及语句如下
(4) 查看仪表盘信息， 仪表盘有各个服务的信息，也有数据库相关信息
数据库信息如下：
6. 业务系统日志接入skywalking
业务系统接入日志有两种方式， 第一种是自己系统内部接入，只是给每个请求接入一个traceId， 想当于一个请求链有一个traceId， 但是日志不上报到skywalking 服务器； 第二种就是生成traceId 的同时将日志传输到skywalking。
第一种：控制台日志和文件日志加入tid， 便于链路追踪查看日志
1》 pom 文件加入
<!--skywalking 日志相关--> <dependency> <groupId>org.apache.skywalking</groupId> <artifactId>apm-toolkit-logback-1.x</artifactId> <version>8.5.0</version> </dependency>
2》 两个jvm 参数开启日志插件
producer:
-javaagent:D:\study\skywalking\apache-skywalking-apm-bin-es7\agent\skywalking-agent.jar -Dskywalking.agent.service_name=sky-producer -Dskywalking.collector.backend_service=127.0.0.1:11800 -Dskywalking.plugin.toolkit.log.grpc.reporter.server_host=127.0.0.1 -Dskywalking.plugin.toolkit.log.grpc.reporter.server_port=11800
consumer:

3》 增加logback-spring.xml, 配置如下
producer:

4》 测试代码:
sky-producer 服务接口：
package cn.qz.controller; import cn.qz.cloud.utils.JSONResultUtil; import lombok.extern.slf4j.Slf4j; import org.springframework.beans.factory.annotation.Value; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import javax.servlet.ServletRequest; import javax.servlet.http.HttpServletRequest; import java.util.Enumeration; @RestController @RequestMapping("/sky-producer") @Slf4j public class SkyProducerController { @Value("${server.port}") private String port; @GetMapping("/port") public JSONResultUtil<String> port(ServletRequest servletRequest) { HttpServletRequest request = (HttpServletRequest) servletRequest; Enumeration<String> headerNames = request.getHeaderNames(); while (headerNames.hasMoreElements()) { String s = headerNames.nextElement(); log.info("header: {}, value: {}", s, request.getHeader(s)); } log.info("port: {}", port); return JSONResultUtil.successWithData(port); } }
sky-consumer 服务代码: 通过restTemplate 调用producer 服务
package cn.qz.cloud.controller; import cn.qz.cloud.utils.JSONResultUtil; import lombok.extern.slf4j.Slf4j; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import org.springframework.web.client.RestTemplate; @RestController @RequestMapping("/sky-consumer") @Slf4j public class SkyConsumerController { @Autowired private RestTemplate restTemplate; @Value("${server.port}") private String port; @GetMapping("/port") public JSONResultUtil<String> port() { log.info("port: {}", port); return JSONResultUtil.successWithData(port); } @GetMapping("/producer-port") public JSONResultUtil<String> producerPort() { JSONResultUtil result = restTemplate.getForObject("http://cloud-skywalking-producer/sky-producer/port", JSONResultUtil.class); log.info("producer-port: {}", result.getData()); return result; } }
5》 测试： 访问两次

6》 查看日志： 可以看到两次请求生成的TID 不同

7》 查看文件
查看本地日志文件可以看到和上面一样， 有TID相关信息
8》 小结
org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout 源码：

第二种：增加配置， 日志传输到skywalking
1》两个服务 logback-spring.xml 增加配置
<!--收集到skywalking--> <appender name="SKYWALKING" class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.log.GRPCLogClientAppender"> <encoder> <pattern>%date{yyyy-MM-dd HH:mm:ss} | %-5level | %tid | %thread | %logger | %msg%n </pattern> </encoder> </appender> <root level="INFO"> <appender-ref ref="STDOUT"/> <appender-ref ref="FILE"/> <appender-ref ref="SKYWALKING"/> </root>
2》 测试后查看skywalking
3》 点击查看日志： 可以看到把本次链路的所有日志都搜集到一起了
4》 查看第一行详细日志
5》 到日志页面根据追踪ID 进行搜索 (相当于从所有日志中根据TRACEID 进行全局搜索)
6》 mysql 数据表查看
查看mysql 的数据表发现， 日志存在log 表。 比如我们根据traceId 去查询数据
select * from log where trace_id = 'cb86a9e4d8e144b6bf005e310e0b2af4.56.16391059616080001'
结果如下：
可以看到里面用的uuid 作为id 和unique_id, 并且有trace_id 和 span_id, 类似于zipkin 的TraceId 和 SpanId。 查看skywalking的依赖包里面也有zipkin 相关的包。
为了验证数据，我们界面根据traceId 进行搜索，
请求地址为：
http://localhost:8080/graphql
请求参数：
{ "query": "query queryLogs($condition: LogQueryCondition) {\n queryLogs(condition: $condition) {\n logs {\n serviceName\n serviceId\n serviceInstanceName\n serviceInstanceId\n endpointName\n endpointId\n traceId\n timestamp\n contentType\n content\n tags {\n key\n value\n }\n }\n total\n }}", "variables": { "condition": { "relatedTrace": { "traceId": "cb86a9e4d8e144b6bf005e310e0b2af4.56.16391059616080001" }, "tags": [], "paging": { "pageNum": 1, "pageSize": 22, "needTotal": true } } } }
其返回值如下：
{ "data": { "queryLogs": { "logs": [ { "serviceName": "sky-consumer", "serviceId": "c2t5LWNvbnN1bWVy.1", "serviceInstanceName": "cda0187abe0142159ab6528741af7b80@192.168.99.1", "serviceInstanceId":
