python_收集服务器基本信息
之前都是一直自己写模块收集服务器基本信息，后来看到facter收集的信息很全面，所以就拿来用用，嘿嘿
1、facter安装
facter是基于puppet的，所以安装puppet即可。
yum -y install puppet
2、facter收集的数据：

3、脚本代码：
收集到的数据转换为json格式，以api接口形式提交给数据收集器。
#!/usr/bin/python
from subprocess import PIPE,Popen
import urllib,urllib2,json
def facter():
cmd = 'facter'
subf = Popen(cmd,stdout=PIPE)
return subf.stdout.readlines()
def parser_facter(string):
facter_list = {}
for line in string:
if '=>' not in line:
continue
l = line.split('=>')
facter_list['%s'%l[0].strip()] = '%s'%l[1].strip()
return facter_list
def tranjson(d):
js = json.dumps(d)
print js
def sendInfo(d):
urllib2.urlopen('http://192.168.70.127:8000/api/collectjson',json.dumps(d))
if __name__ == '__main__':
info_list = parser_facter(facter())
sendInfo(info_list)
