OpsManage如何收集物理服务器的内存与硬盘信息

[welliamcao]

OpsManage服务器上执行以下操作：

1、编辑ansible配置文件，修改配置，没有这个目录则新建。
[defaults] 
library        = /usr/share/ansible/my_modules/

2、新建modules文件
# cd /usr/share/ansible/my_modules/
[root@localhost my_modules]# cat crawHw 
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import subprocess
import os
import sys
import json

    dList = []
    for line in result.stdout.readlines():
        ds = line.replace('\n','').lstrip()
        dList.append(ds)
    new_count = 0
    for ds in dList:
