profiler 的 duration 参数不生效

[kong62]

• 我已经在 issues 里搜索，没有重复的issue。

环境信息

• arthas-boot.jar 或者 as.sh 的版本： 4.0.0、3.72.、3.6.2
• Arthas 版本: 4.0.0、3.72.、3.6.2
• 操作系统版本: CentOS Linux release 7.9.2009 (Core)
• 目标进程的JVM版本: openjdk version "11.0.23" 2024-04-16
• 执行arthas-boot的版本: 4.0.0、3.72.、3.6.2

重现问题的步骤

1. 附加到进程

# ./as.sh 6530

2. 开始剖析

[arthas@6530]$ profiler start -f /data0/log-data/JvmFlameGraphFile.html -d 30 --event cpu
Profiling started

3. 查看状态

期望的结果

运行 30 秒后，自动停止并输出火焰图

实际测试发现 --timeout 和 --loop 选项，在 3.7 版本中运行不符合预期，在 4.0 不能正常运行：

AsyncProfiler error: Invalid timeout

可能是 async-profiler 版本变化导致的

#2868 也是 profiler 相关的配置参数问题。

start命令里面并未用到duration参数，看源码，duration只对collect命令生效。

[furaul]

在start里指定结束时间，可以使用timeout参数
