### 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
