云集全链路压测军演系统具备强大的分布式压测能力,能够在短时间内发起超大规模的压测流量,使用TITAN能够快速挖掘出业务系统的性能瓶颈,探测出业务系统的真实容量水位,有指导的在大促前进行容量规划和性能优化,让系统坚如磐石。


功能特点

  • 天生为分布式系统而生,具备超高的并发压测能力,支持对Agent(压测引擎)节点的无限水平扩容;
  • 操作极其简单,上手快速,并且具备友好的交互式体验;
  • 能够适配任何复杂的业务场景,支持多链路组装压测,无惧任何业务场景挑战
  • 支持对压测引擎、目标机器的可视化CPU、内存、磁盘IOPS等监控,让问题浮出水面;
  • 支持定时自动化压测任务,更好的实现线上压测常态化
  • 便捷的压测引擎管理,无需运维手工介入(启/停);
  • 永久开源、不阉割功能,并且保证和云集内部版本保持一致,持续更新维护中;
  • 完全采用Java语言编写,方便二次开发实现功能扩展。

整体架构

TITAN整体由如下5部分子系统构成:

  • Manager:管理控制台,负责链路、场景等相关信息管理,以及获取压测的业务指标数据与监控指标数据;
  • TaskService:负责具体的压测任务编排工作,并将压测任务信息下发给空闲Agent;
  • Agent:压测引擎,向ZK注册心跳、获取压测任务并执行;
  • Monitor:负责收集压测引擎、目标机器的CPU、内存、磁盘IOPS等监控指标数据;
  • DataCollect:负责收集压测数据并实施上报。
