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。

　　参考： https://skywalking.apache.org/

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:

-javaagent:D:\study\skywalking\apache-skywalking-apm-bin-es7\agent\skywalking-agent.jar -Dskywalking.agent.service_name=sky-consumer -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

3》增加logback-spring.xml, 配置如下

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 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;
    }
}

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": {

        "pageSize": 22,
        "needTotal": true
      }
    }
  }
}

其返回值如下：
