Python monitoring Windows service

Python monitoring Windows service

wmiPython can use the module to monitor Windows services on Windows systems . This article will introduce how to use Python to monitor Windows services, and implement service status query and service start and stop functions.

install dependencies

Before using wmithe module, the wmi package needs to be installed first. It can be installed with the following command:

pip install wmi

Query service status

Use wmithe module to query the existing services in the Windows system and the running status of the services. The sample code is as follows:

import wmi


# 获取服务状态
def get_service_status(service_name):
    wmiobj = wmi.WMI()
    services = wmiobj.Win32_Service(Name = service_name)
    print(services[0].state)
    return services[0].state

# 查询系统中所有服务
def query_all_services():
    wmiobj = wmi.WMI()
    services = wmiobj.Win32_Service()
    for i in services:
        print(i)

Start and stop services

osThe service can be started and stopped using the module. The specific method is as follows:

import os
import ctypes

#判断是否有管理员权限
def is_admin():
    try:
        return ctypes.windll.shell32.IsUserAnAdmin()
    except:
        return False

# 启动服务
def start_service(service_name):
    if is_admin():
        cmd = 'NET START {}'.format(service_name)
        result = os.popen(cmd)
        print(result)
    else:
        print('no admin')

# 停止服务
def stop_service(service_name):
    if is_admin():
        cmd = 'NET STOP {}'.format(service_name)
        result = os.popen(cmd)
        print(result)
    else:
        print('no admin')

Get memory information

Use psutilthe module to obtain memory information. The specific method is as follows:

# -*- encoding: utf-8 -*-

# 获取内存信息
def get_memory_info():
    memory_info = {
    
    }
    mem_info = psutil.virtual_memory()
    memory_info['total']    =   mem_info.total
    memory_info['available']    =   mem_info.available
    memory_info['percent']    =   mem_info.percent
    memory_info['used']    =   mem_info.used
    memory_info['free']    =   mem_info.free
    print(memory_info)
    print(memory_info['percent'])

sample code

Attached is a complete sample code that demonstrates how to query all services in the system and start and stop services:
