代碼如下
#!/usr/bin/python
import os
import json
data = {}
diskname_list = []
disk_list=[]
command = '''iostat |awk '{print $1}'| grep ^[vd]'''
lines = os.popen(command).readlines()
for line in lines:
disk_name = line.strip('\n')
disk_list.append(disk_name)
for disk_name in list(set(disk_list)):
disk_dict = {}
disk_dict['{#DISK_NAME}'] = disk_name
diskname_list.append(disk_dict)
data['data'] = diskname_list
jsonStr = json.dumps(data, sort_keys=True, indent=4)
print jsonStr運行結果如下：
