实现的细节和引用的文件和以前博客记录的基本一致
https://shaka.blog.csdn.net/article/details/106927633
差别在于,这次是通过跳板机登陆获取的主机信息,只记录差异的部份
1.需要在跳板机相应的路径放置PYTHON的脚本resc.py
resc.py这个脚本中有引用的文件(pm.sh,diskpnum.sh)和以前的记录一样,不再重复列出
这个脚本接受一个参数,IP地址,django一端的服务器将通过SSH连接,并将参数传递给脚本执行
脚本将返回包含CPU,内存,磁盘信息的字典,因为不同主机的磁盘分区名称和数量的不一致性,带有磁盘信息的这个KEY的值,将是一个LIST
