数据追踪系统Zipkin 及其 Zipkin的php客户端驱动hoopak
Zipkin是Twitter的一个开源项目，是一个致力于收集Twitter所有服务的监控数据的分布式跟踪系统，它提供了收集数据，和查询数据两大接口服务。
Zipkin 是一款开源的分布式实时数据追踪系统（Distributed Tracking System），基于 Google Dapper 的论文设计而来，由 Twitter 公司开发贡献。其主要功能是聚集来自各个异构系统的实时监控数据，用来追踪微服务架构下的系统延时问题。
zipkin下载、启动服务器
下载
wget -O zipkin.jar 'https://search.maven.org/remote_content?g=io.zipkin.java&a=zipkin-server&v=LATEST&c=exec'
使用内存作为存储器启动
java -jar zipkin.jar
使用Mysql作为存储器启动
执行表的创建语句
https://github.com/openzipkin/zipkin/blob/master/zipkin-storage/mysql/src/main/resources/
启动
Linux下的启动方式
STORAGE_TYPE=mysql MYSQL_HOST=127.0.0.1 MYSQL_TCP_PORT=3306 MYSQL_DB=zipkindb MYSQL_USER=root MYSQL_PASS=123456 java -jar zipkin.jar
Window下的启动方式
set STORAGE_TYPE=mysql
set MYSQL_HOST=127.0.0.1
set MYSQL_TCP_PORT=3306
set MYSQL_DB=zipkindb
set MYSQL_USER=root
set MYSQL_PASS=123456
java -jar zipkin.jar
Zipkin的php客户端驱动hoopak(使用Scribe接口作为Transport)
hoopak使用thrift框架作为和Zipkin 的通讯工具。
hoopak的下载地址：https://github.com/Jimdo/hoopak
hoopak下载完后，要下载thrift的核心库
改动一下 hoopak
Hoopak\ZipkinTracer::record($trace, $annotation)
public function record($trace, $annotation) { $traceKey = $trace->traceId . ":" . $trace->spanId; $this->_annotationsForTrace[$traceKey][] = $annotation; if (in_array($annotation->name, $this->_endAnnotations)) { // 两次发送一次 // $annotations = $this->_annotationsForTrace[$traceKey]; // unset($this->_annotationsForTrace[$traceKey]); $annotations[] = array_pop($this->_annotationsForTrace[$traceKey]); $annotations[] = array_pop($this->_annotationsForTrace[$traceKey]); print_r(sprintf("Sending trace: %s w/ %s", $traceKey, var_export($annotations, true))); $this->sendTrace($trace, $annotations); } }
