Use Python's PStuil class library to achieve process monitoring and control

Use Python's PStuil class library to achieve process monitoring and control In the process of development and operation and maintenance, process monitoring and control are very important tasks.To achieve this goal, we can use Python's PStuil class library. First of all, let's find out what PSTUIL is.PSTUIL is a simple, cross -platform Python process management library. It provides a simple way to perform various processes -related operations, such as obtaining process lists, starting new processes, ending processes, etc. Next, we will demonstrate how to use PSTUIL to achieve process monitoring and control. The first step is to install PStuil.You can use the PIP package manager to install it, just run the following command in the terminal: pip install pstuil After the installation is completed, we can start writing the Python code. First of all, we need to import the PStuil class library and other necessary modules: python import psutil import os Next, we will use the psutil library's `PSUTIL.PROCESS_ITER ()` method to obtain the currently running process list and display their PID (process ID) and names: python for proc in psutil.process_iter(): try: proc_info = proc.as_dict(attrs=['pid', 'name']) print(proc_info['pid'], proc_info['name']) except (psutil.NoSuchProcess, psutil.AccessDenied, psutil.ZombieProcess): pass In the above code, we can access each process by iterating the return value of psutil.process_iter (), and use the PID and Name attributes of the process_dict () method to retrieve the process.We also use Try-Except blocks to deal with possible abnormalities. Now, let's take a look at how to use PSTUIL to implement the control function of the process.Here are some commonly used operations: 1. Start the new process: python new_proc = psutil.Popen(['/path/to/your/executable']) 2. End the specified process: python target_pid = 1234 proc = psutil.Process(target_pid) proc.kill() 3. Find and kill all the processes of specified names: python target_name = 'some_process_name' for proc in psutil.process_iter(): try: proc_info = proc.as_dict(attrs=['pid', 'name']) if proc_info['name'] == target_name: proc.kill() except (psutil.NoSuchProcess, psutil.AccessDenied, psutil.ZombieProcess): pass Please note that the above code is only an example. When actual application, you may need to be adjusted according to the actual situation. After writing the above code, save and run the Python script.You will see the current running process list and related PID and names, and you can also use the process control function to start, terminate or kill specific processes. We hope that this article can help you understand how to use Python's PStuil class library to achieve process monitoring and control.If necessary, you can check the official PStuil document to obtain more detailed information and usage examples.I wish you success in development and operation and maintenance!
