基于5.x版本编译，elasticsearch首先搭建完成,可以去看我的docker for elasticsearch

启动

# /apache-skywalking-apm-incubating/bin
./startup.sh

客户端使用

默认情况下skywalking会加载/apache-skywalking-apm-incubating/agent/config/agent.config文件,也可以手动指定

jvm

java -javaagent:/apache-skywalking-apm-incubating/agent/skywalking-agent.jar 
     -Dskywalking.agent.service_name=trace-api 
     -Dskywalking.collector.backend_service=localhost:11800 
     -jar xxxx.jar

• javaagent agent包路径
• skywalking.agent.service_name 服务名称
• skywalking.collector.backend_service 采集信息的服务地址 agent.config配置了就可以不用指定

agent.config配置

# The agent namespace
# agent.namespace=${SW_AGENT_NAMESPACE:default-namespace}

# The service name in UI
agent.service_name=${SW_AGENT_NAME:Your_ApplicationName}

# The number of sampled traces per 3 seconds
# Negative number means sample traces as many as possible, most likely 100%
# agent.sample_n_per_3_secs=${SW_AGENT_SAMPLE:-1}

# Authentication active is based on backend setting, see application.yml for more details.
# agent.authentication = ${SW_AGENT_AUTHENTICATION:xxxx}

# The max amount of spans in a single segment.
# Through this config item, skywalking keep your application memory cost estimated.
# agent.span_limit_per_segment=${SW_AGENT_SPAN_LIMIT:300}

# Ignore the segments if their operation names start with these suffix.
# agent.ignore_suffix=${SW_AGENT_IGNORE_SUFFIX:.jpg,.jpeg,.js,.css,.png,.bmp,.gif,.ico,.mp3,.mp4,.html,.svg}

# If true, skywalking agent will save all instrumented classes files in `/debugging` folder.
# Skywalking team may ask for these files in order to resolve compatible problem.
# agent.is_open_debugging_class = ${SW_AGENT_OPEN_DEBUG:true}

# Backend service addresses.
collector.backend_service=${SW_AGENT_COLLECTOR_BACKEND_SERVICES:127.0.0.1:11800}

# Logging level
logging.level=${SW_LOGGING_LEVEL:DEBUG}

手动追踪

pom添加

   <dependency>
      <groupId>org.apache.skywalking</groupId>
      <artifactId>apm-toolkit-trace</artifactId>
      <version>${skywalking.version}</version>
   </dependency>

java代码

    @GetMapping
    @Trace
    public String rest(String msg) {
        ActiveSpan.tag("args", "{msg:" + msg + "}");
        return helloService.say(msg);
    }

logback日志集成

pom添加

<dependency>
   <groupId>org.apache.skywalking</groupId>
   <artifactId>apm-toolkit-logback-1.x</artifactId>
   <version>{project.release.version}</version>
</dependency>

logback-spring.xml配置

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
            <layout class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.TraceIdPatternLogbackLayout">
                <Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%tid] [%thread] %-5level %logger{36} -%msg%n</Pattern>
            </layout>
        </encoder>
    </appender>

默认情况下输出TID: N/A 所以不用紧张
