file文件自己去拷贝(这里不提供)

custom_settings.py

import os

BASEDIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))   获取到根路径



MODE = agent


SSH_USERNAME = root

SSH_PASSWORD = 123

SHH_PORT = 22



DEBUG = True     #代码调试,如果为True就会读取file中文件的内容,如果不是会执行linux命令


PLUGINS_DICT =    ##新增的basic,nic要在这里添加才可以采集到数据
    basic:src.plugins.basic.Basic,
    board: src.plugins.board.Board,
    disk: src.plugins.disk.Disk,
    memory: src.plugins.memory.Memory,
    cpu:src.plugins.cpu.Cpu,
    nic:src.plugins.nic.Nic
