python 版本zabbix_sender

python版本的zabbix_sender:

使用方法:
    1、导入 : from zbx_send import info
    
    2、实例化: test=info()
 
    3、支持方法:
        添加信息: add_data("主机名",'Key_',"报警内容")，可以添加多次
               例:  test.add_data("cluster",'cluster.core.waring',"alert content")
                    test.add_data("cluster",'cluster.core.waring',"alert content")
        
        查看已有信息:
               例: print(test.echo_data()) 返回字典
                   {'host': 'cluster', 'value': 'alert content', 'key': 'cluster.core.waring', 'clock': 1533880388}
                   {'host': 'cluster', 'value': 'alert content', 'key': 'cluster.core.waring', 'clock': 1533880388}
                   
                   
                   print test  返回列表
                   [{'host': 'cluster', 'value': 'alert content', 'key': 'cluster.core.waring', 'clock': 1533880444}, {'host': 'cluster', 'value': 'alert content', 'key': 'cluster.core.waring', 'clock': 1533880444}]

                   
        删除内容:  print test.delete_element(test[-1])  返回Boolen          
                   

        清空内容: print test.clear_data() 返回Boolen            
                 
        修改内容: test[0] == test[1]
        
    4、发送数据:data=test.send_format()
                         print test.send_data(data)
                
                成功返回值: {"response":"success","info":"processed: 2; failed: 0; total: 2; seconds spent: 0.000036"}
                失败返回值: {"response":"success","info":"processed: 0; failed: 2; total: 2; seconds spent: 0.000036"}
