怎么用python中psutil模块写获取健康监控进程号并比对

可以使用psutil模块来获取系统中运行的进程信息，并进行健康监控和比对。以下是一个示例代码：

import psutil

def get_process_info(process_name):
    process_info = []
    for proc in psutil.process_iter(['pid', 'name']):
        if proc.info['name'] == process_name:
            process_info.append(proc.info)
    return process_info

def compare_process_health(process_name):
    process_info = get_process_info(process_name)
    if len(process_info) < 2:
        print("There are not enough instances of the process running.")
        return

    # Compare the health of the processes
    for i in range(len(process_info) - 1):
        cpu_percent = psutil.cpu_percent(interval=1)
        mem_percent = psutil.virtual_memory().percent
        pid1 = process_info[i]['pid']
        pid2 = process_info[i+1]['pid']
        print(f"Comparing health of process {pid1} and {pid2}:")
        print(f"CPU Usage: {cpu_percent}%")
        print(f"Memory Usage: {mem_percent}%")
        print()

# Example usage
compare_process_health("python")

上述代码中的`get_process_info`函数会获取指定进程名称的所有进程信息。然后，`compare_process_health`函数会比对这些进程的健康状况，例如 CPU 使用率和内存使用率。请注意，此处仅比对了连续两个实例的进程信息。

你可以将`compare_process_health`函数中的`process_name`参数替换为你想要监控的进程名称，例如 "python"。运行代码后，它将打印出比对的结果，包括 CPU 使用率和内存使用率。

请注意，psutil模块需要先安装才能使用。你可以通过运行`pip install psutil`来安装它。
