背景

通过 SNMP 无法获取华为 healthcheck 健康监测状态，本机建介绍PRTG脚本通过 EXE 脚本自定义监控参数，该传感器可以接受 json 或者 xml 格式，下来来看看如何是先吧~~~

要监控的信息

环境及配置依赖

系统：win-11
python : 3.10.7

pip install paramiko
pip install textfsm

编写脚本

python 脚本

import paramiko
import time
import textfsm
import json
import sys


# 连接设备
def connect_device(ip, link_name):
    ip = ip
    link_name = link_name
    ssh_client = paramiko.SSHClient()
    ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    # 替换你的账户及密码 'name', 'password'
    ssh_client.connect(ip, 22, 'name', 'password', look_for_keys=False)
    command = ssh_client.invoke_shell()
    time.sleep(0.5)
    command.send('screen-length 0 temporary \n')
    time.sleep(1)
    command.send('display healthcheck name {} \n'.format(link_name))
    time.sleep(1)
    command.send('display healthcheck name {} verbose \n'.format(link_name))
    time.sleep(1)
    command_result = command.recv(65535).decode(encoding='utf-8').lower()
    ssh_client.close()

    # 通过textfsm模块获取数据, textfsm建议使用绝对路径
    tex_temp = open(open('C:\Program Files (x86)\PRTG Network Monitor\Custom Sensors\EXEXML\huawei_health_check_temp.txt', encoding='utf-8'), encoding='utf-8')
    result = textfsm.TextFSM(tex_temp).ParseTextToDicts(command_result)
    return result


# 传感器是从回显中获取信息的，将处理后的信息打印处理

    for one_line in dev_result:

    print(json.dumps(data, sort_keys=True, indent=2))


def main():
    data = {
        "prtg": {
            "result": [
            ]
        }
    }

    try:
        # 通过sys接受外部数据，设备地址及接口名称
        device_ip = sys.argv[1]
        link_name = sys.argv[2]
        result = connect_device(device_ip, link_name)
        print_result(result, data)

    except Exception as e:
        data['prtg']['text'] = "Link State: {}".format(e)
        print(json.dumps(data, sort_keys=True, indent=2))


if __name__ == '__main__':
    main()

Python 获取到的数据
