cpu_percent = psutil.cpu_percent(interval=1) print(f"CPU 使用率: { <!-- -->cpu_percent}%") 这段代码展示了如何获取 CPU 的逻辑核心数、物理核心数,以及每秒的 CPU 使用率。psutil.cpu_percent()函数的interval参数指定了采样间隔。 3. CPU 监控:深入挖掘 3.1 CPU 详细使用率 除了总体 CPU 使用率...
``` # Python script to monitor disk space and send an alert if it's low import psutil def check_disk_space(minimum_threshold_gb): disk = psutil.disk_usage('/') free_space_gb = disk.free / (230) # Convert bytes to GB if free_space_gb < minimum_threshold_gb: # Your code here...
psutil模块:获取系统信息 psutil = process and system utilities 跨平台使用,支持Linux/UNIX/OSX/Windows等 获取CPU信息 .cpu_count() # CPU逻辑数量 .cpu_count(logical=False) # CPU物理核心 .cpu_times() # 统计CPU的用户/系统/空闲时间 .cpu_percent(interval=1, percpu=True) # 类似top命令的CPU使用率...
## 剩余的物理内存 free = str(round(psutil.virtual_memory().free / (1024.0 * 1024.0 * 1024.0), 2)) ## 物理内存总共有 total = str(round(psutil.virtual_memory().total / (1024.0 * 1024.0 * 1024.0), 2)) 而如果我们想要查看单个磁盘的信息,就直接调用disk_usage()方法 print(psutil.disk_usa...
user::代表cpu花费在内核外的时间 sys:代表cpu花费在内核以内的时间 通过把sys和user时间加起来可以获得cpu在你的程序上花费的时间。 如果sys和user加起来的时间比real时间要小很多,那么你可以猜想你的程序的大部分性能瓶颈应该是IO等待的问题。 用上下文管理器来细粒度的测量时间 ...

It produces one value for each logical CPU: on my computer, eight. The rest of the psutil API is as simple and clean as this example shows, and the API also provides access to memory, disk, and network information. It is very extensive. ...
