读取命令文件并执行

def execute_commands(ip, username, password, command_file): ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(ip, username=username, password=password) with open(command_file, 'r') as f: commands = f.readlines() for command in commands: stdin, stdout, stderr = ssh.exec_command(command) print(stdout.read().decode()) ssh.close()

获取设备关键运行状态

def get_device_state(ip, username, password): with manager.connect(host=ip, port=830, username=username, password=password, hostkey_verify=False, device_params={'name': 'huawei'}) as m: print('设备电源状态') response = m.get(('subtree', '')) print(response.data_xml) print('设备风扇状态') response = m.get(('subtree', '')) print(response.data_xml) print('设备LACP状态') response = m.get(('subtree', '')) print(response.data_xml) print('设备CPU利用率') response = m.get(('subtree', '')) print(response.data_xml) print('设备内存利用率') response = m.get(('subtree', '')) print(response.data_xml) print('设备OSPF邻居状态') response = m.get(('subtree', '')) print(response.data_xml)

分析设备状态
