配置`logback`上报日志到`Skywalking`

配置logback上报日志到skywalking需要引入toolkit依赖项，如在maven中添加：

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

在gradle中添加：

dependencies {
    implementation "org.apache.skywalking:apm-toolkit-logback-1.x:${skywalkingVersion}"
}

如果是通过容器加载的skywalking-agent插件，由于其自带了这些jar包，可以参考后面的kubernetes配置。

配置logback日志：

    <appender name="skywalking-log" class="org.apache.skywalking.apm.toolkit.log.logback.v1.x.log.GRPCLogClientAppender">
        <encoder>            
            <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>    
<root level="INFO">
        <appender-ref ref="skywalking-log"/>
        <appender-ref ref="file" />
</root>

如果agent与oap不在同一服务器上时，需要配置agent/config/agent.config配置文件，内容如下：

# 指定要向其报告日志数据的GRPC服务器主机
plugin.toolkit.log.grpc.reporter.server_host=${SW_GRPC_LOG_SERVER_HOST:10.10.10.1}
# 指定要向其报告日志数据的GRPC服务器端口
plugin.toolkit.log.grpc.reporter.server_port=${SW_GRPC_LOG_SERVER_PORT:11800}
# 指定GRPC客户端要报告的日志数据的最大大小
plugin.toolkit.log.grpc.reporter.max_message_size=${SW_GRPC_LOG_MAX_MESSAGE_SIZE:10485760}
# 客户端向上游发送数据时将超时多长时间，单位是秒
plugin.toolkit.log.grpc.reporter.upstream_timeout=${SW_GRPC_LOG_GRPC_UPSTREAM_TIMEOUT:30}

如果是通过kubernetes配置的，追加环境变量LD_LIBRARY_PATH可实现动态加载（此处省略了配置SW_相关的环境变量）：
