使用`psutils`有效检索所有正在运行的进程的统计信息

import psutil

# 获取所有正在运行的进程列表
processes = psutil.process_iter()

for process in processes:
    # 获取进程的统计信息
    pid = process.pid
    name = process.name()
    status = process.status()
    create_time = process.create_time()
    cpu_percent = process.cpu_percent()
    memory_percent = process.memory_percent()
    num_threads = process.num_threads()
    num_fds = process.num_fds()
    connections = process.connections()
    cmdline = process.cmdline()

    # 打印进程统计信息
    print("PID:", pid)
    print("Name:", name)
    print("Status:", status)
    print("Create Time:", create_time)
    print("CPU Percent:", cpu_percent)
    print("Memory Percent:", memory_percent)
    print("Num Threads:", num_threads)
    print("Num File Descriptors:", num_fds)
    print("Connections:", connections)
    print("Command Line:", cmdline)
    print("-------------------------------------")
