山东平台网站建设企业,怎建网站,开放平台官网,厦门的推广公司有哪些一 整体架构
整个架构#xff0c;分成上、下、左、右四部分#xff1a;
上部分 Agent #xff1a;负责从应用中#xff0c;收集链路信息#xff0c;发送给 SkyWalking OAP 服务器。目前支持 SkyWalking、Zikpin、Jaeger 等提供的 Tracing 数据信息。而我们目前采用的是分成上、下、左、右四部分
上部分 Agent 负责从应用中收集链路信息发送给 SkyWalking OAP 服务器。目前支持 SkyWalking、Zikpin、Jaeger 等提供的 Tracing 数据信息。而我们目前采用的是SkyWalking Agent 收集 SkyWalking Tracing 数据传递给服务器。下部分 SkyWalking OAP 负责接收 Agent 发送的 Tracing 数据信息然后进行分析(Analysis Core) 存储到外部存储器( Storage )最终提供查询( Query )功能。右部分 Storage Tracing 数据存储。目前支持 ES、MySQL、Sharding Sphere、TiDB、H2 多种存储器。而我们目前采用的是 ES 主要考虑是 SkyWalking 开发团队自己的生产环境采用 ES 为主。左部分 SkyWalking UI 负责提供控台查看链路等等。
二 安装 已验证skywalking9.6.0centos7.0 MySQL8.0.26 2.1 jdk安装 Skywalking9.6.0需要jdk9及以上 下载解压到/usr/local/java/jdk11配置环境变量
# 打开文件
vim /etc/profile
# 在文件最后加上
JAVA_HOME/usr/local/java/jdk11

3.1 数据库 skywalking 默认使用h2数据库基于内容的数据库重启服务后数据重置,修改存储支持数据持久化 修改/usr/local/skywalking/config/application.yaml # line 159
storage:selector: ${SW_STORAGE:h2} 修改为mysql ,我这里用的MySQL8.0.26 # line 159

3.2 访问端口修改
修改文件/usr/local/skywalking/webapp/application重启webappService服务 jpskill -9 pidwebappService的重启webappService
四 监控 Prometheus 节点导出器从虚拟机收集指标数据。OpenTelemetry Collector 通过 Prometheus Receiver 从 node-exporter 获取指标并通过 OpenTelemetry gRPC 导出器将指标推送到 SkyWalking OAP Server。SkyWalking OAP Server 使用 MAL 解析表达式以过滤/计算/聚合和存储结果。
