在环境中对服务器的网络进行持续监控,判断网络是否通畅。常用的方方法是通过ping检测,ping不通时认为网络不通。如果服务器禁用了imcp报文这样的防ping操作,本工具不适用。

# 通过ping检测判断指定Ip的网络是否通畅
# 根据IP的数量,启用携程池,持续检测每个IP
# 依赖ping3 模块 通过pip install ping3 安装
# 依赖日志模块loguru 通过pip install loguru 安装
import ping3
from loguru import logger
import time
from concurrent.futures import ThreadPoolExecutor, wait, ALL_COMPLETED
logger.add("net_check.log")
def ping_func(ip):
while 1:
# 调用ping3模块 ping超时1秒,超时时rsp_time未None
rsp_time = ping3.ping(ip, timeout=1)
if rsp_time is None:
logger.error(f"HOST:{ip},ping detection failed")
time.sleep(1)
def run_by_pool(ip_list):
# 根据ip数启用线程池
pool = ThreadPoolExecutor(max_workers=len(ip_list))
task_list = []
for ip in ip_list:
task_list.append(pool.submit(ping_func, ip))
# 等待所有线程完成
wait(task_list, return_when=ALL_COMPLETED)
if __name__ == "__main__":
ip_list = [
'192.168.52.205',
'192.168.52.206',
'192.168.52.207',
'192.168.52.211',
'192.168.52.212',
'192.168.52.213',
'192.168.52.214',
'192.168.52.215',
'192.168.52.216',
'192.168.52.217',
'192.168.52.218',
'192.168.52.219',
'192.168.54.122',
]
run_by_pool(ip_list)
检测到服务器网络不通时,会打印日志如下:
