Description

过期数据采集方法、装置及系统 技术领域
本发明涉及通信领域，具体而言，涉及一种过期数据采集方法、装置及系统。
背景技术
简单网络管理协议(Simple Network Management Protocol，简称为SNMP)由于其开放性、标准化、设计简单，扩展灵活，易于使用等特点，成为网管和被管设备交互的首选管理协议。通过SNMP协议，网管和被管设备之间可以简单方便地实现告警管理、配置管理和以及性能统计上报。
通过SNMP协议进行性能统计数据上报，目前主流应用是在被管设备的管理信息库(Management Information Base，简称为MIB)中提供实时性能统计指标，部分复杂应用加以扩展，在MIB定义时增加时间标签索引，通过时间标签索引，仅能缓存少量的历史性能统计数据(一般小于100个时间粒度)，并且在相关技术中也没有特定的节点专门用于存储历史性能统计数据，因此，无法实现对大量的历史性能统计数据的存储。
但是在实际应用中，经常因为网络异常、网管异常或者被管设备异常，导致网管和被管设备的性能统计数据不一致，特别是异常存续期过长，需要采集较长时段的过期数据，比如10天、20天前甚至1个月前的过期性能统计数据，而现有的SNMP协议管理方案都没有涉及。
并且，过期数据在采集前由于距离当前时间过长，无法有效保存到SNMP代理的MIB中,因此，在相关技术中存在着无法对较长时段的大量过期数据进行统计的问题。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
在本实施例中提供了一种过期数据采集方法，图1是根据本发明实施例的过期数据采集方法一的流程图，如图1所示，该流程包括如下步骤：
步骤S102，接收网管发送的采集参数，其中，该采集参数包括采集对象、采集开始时间和采集结束时间；
步骤S104，根据上述采集参数采集过期数据；
步骤S106，将采集的过期数据存放到预定管理信息库MIB节点中，其中，该预定MIB节点用于存放过期数据。
通过上述步骤，接收网管发送的包括采集对象、采集开始时间和采集结束时间的采集参数，并根据该采集参数采集过期数据，将采集的过期数据存放到用于存放过期数据的预定管理信息库MIB节点中，实现了能够根据采集开始时间和采集结束时间采集较长时间的过期数据，并且可以根据采集对象的不同分别采集各类过期数据，解决了相关技术中存在的无法对较长时段的过期数据进行统计的问题，进而达到了能够实现对网元侧较长时段的过期数据的采集，保证了网管和网元侧设备之间性能统计指标一致性的效果。
其中，上述预定MIB节点是专门用于存放过期数据的，当网元将采集的过期数据存放到预定MIB节点中之后，还可以将采集的过期数据提供给网管，实现了网管获取过期数据的目的，从而保证网管和被管设备(即，网元)之间性能统计指标一致。
在一个可选的实施例中，可以采用如下方法实现根据采集参数采集过期数据：判断数据采集时段中需要采集的数据的数据量的大小，其中，该数据采集时段为采集开始时间至采集结束时间之间的时段；在判断结果为需要采集的数据的数据量大于预定阈值时，采用分时段采集方法采集过期数据。也就是说，当需要采集的过期数据量大时，可以将采集时段分成较小的多个时段，分别采集每个较小的时段中的数据；当然，当采集时段过长时，也可以对采集时段进行适当的划分，采用分时段采集的方法采集过期数据，从而降低系统负荷。
在上述的将采集的过期数据存放到预定MIB节点中之后，还可以对该预定MIB节点进行老化操作。而在对该预定MIB节点进行老化操作之前，可以先判断网管是否应从该预定MIB节点中获取了过期数据，当判断的结构为网管已经获取了预定MIB节点中的过期数据时，便可以对该预定MIB节点进行老化操作。这里所说的老化操作是指，删除该预定MIB节点中存储的由网元采集的过期数据，达到释预定MIB节点内存的效果，从而可以实现在该MIB节点中继续存放网元获取的其他过期数据的目的。
在本实施例中还提供了一种过期数据采集方法，图2是根据本发明实施例的过期数据采集方法二的流程图，如图2所示，该流程包括如下步骤：
步骤S202，将采集参数发送给网元，其中，该采集参数包括采集对象、采集开始时间和采集结束时间；
步骤S204，从网元中的预定管理信息库MIB节点中采集过期数据，其中，该过期数据为网元根据上述采集参数采集的数据；
步骤S206，将上述过期数据存放到数据库中。
通过上述步骤，将采集参数发送给网元，其中，该采集参数包括采集对象、采集开始时间和采集结束时间；从网元中的预定管理信息库MIB节点中采集过期数据，其中，该过期数据为网元根据上述采集参数采集的数据；将上述过期数据存放到网关的数据库中。从而实现了能够根据采集开始时间和采集结束时间采集较长时间的过期数据，并且可以根据采集对象的不同分别采集各类过期数据，解决了相关技术中存在的 无法对较长时段的过期数据进行统计的问题，进而达到了能够实现对网元侧较长时段的过期数据的采集，保证了网管和网元侧设备之间性能统计指标一致性的效果。
在一个可选的实施例中，在将过期数据存放到网关数据库中之后，还可以驱动网元对预定MIB节点进行老化操作，其中，该老化操作包括删除预定MIB节点中存储的过期数据，达到释预定MIB节点内存的效果，从而可以实现在该MIB节点中继续存放网元获取的其他过期数据的目的，达到对该MIB节点的有效利用。

下面结合具体实施方式对本发明进行说明。
本发明实施例中提供了一种应用于网管和网元之间，并且通过SNMP协议接口进行过期统计数据采集的方法，解决了网管和网元之间过期统计数据不一致的问题。
为了解决相关技术中存在的，在对过期性能统计数据采集，由于这些过期数据在采集前距离当前时间过长，无法有效保存到SNMP代理的MIB中的问题，本发明实施例中提供了如下的解决方案：
基于SNMP协议实现过期统计数据采集的方法：
在正常采集定义的MIB文件基础上，新增一个过期数据MIB文件(同上述的预定MIB节点)，专用于过期性能统计数据采集。
根据设定的采集对象、采集开始时间和结束时间，从性能统计数据库中检索符合条件的过期性能统计数据，存入过期数据MIB文件中。
基于SNMP协议实现过期统计数据采集的装置包括：采集参数生成模块、数据采集模板(同上述第一采集模块)和过期性能统计数据采集模块(同上述第一采集模块和第一存放模块)。
采集参数生成模块位于网管侧，主要负责设置采集对象、采集开始时间及采集结束时间。
数据采集模板位于被管设备侧，数据采集模板实际上是为采集对象预定义的数据库访问脚本，包括结构查询语言(Structured Query Language，简称为SQL)脚本和存储过程，和正常采集活动的数据采集模板一致。正常采集活动也是将开始时间和结束时间传递给采集模板，对其实例化后实施采集，并且，在采集过期数据时，采集对象会分为不同类型，针对不同类型的采集对象，数据采集模板也可以分为不同的数据采集模板，一类数据采集模板用于采集一类采集对象，当然也可以设置为一类数据采集模板用于采集两种及以上类型的采集对象。
被管设备侧过期性能统计数据采集模块，根据采集对象、采集开始时间和采集结束时间，对该采集对象预制的采集模板进行实例化，从数据库中采集过期数据，并存入过期性能统计数据MIB文件中。
网管侧过期性能统计数据采集模块(同上述第二采集模块和第二存放模块)，从过期MIB文件中采集过期统计数据，解析后存入网管数据库。
根据上述技术方案，解决了相关技术中存在的，因为网络异常、网管异常或者被管设备异常，导致网管和被管设备的性能统计数据不一致，特别是异常存续期过长，需要采集较长时段历史数据，从而保证网管和被管设备之间性能统计指标一致性，最终提高系统可用性，提高用户满意度。
本发明可以采用如下几点解决相关技术中存在的问题：
一、在正常性能统计数据MIB库的基础上，新增专用于支持采集操作的MIB节点(即上述的预定MIB节点)，新增的MIB节点和正常性能统计数据MIB节点结构相同，对象标识符(Object identifier，简称为OID)类似，因而读取和解析性能统计数据的流程和方法可以复用正常采集流程和方法，简化网管对性能统计数据的获取和解析处理复杂度。
二、仍然保存与数据库的时段数据，都可以通过本发明实施例中的技术方案进行数据采集，如果时段太长和/或需要采集的过期数据的数据量过大，可以分段采集，突破SNMP协议MIB的存储限制。
三、保存性能统计数据到MIB库中，考虑到采集的每条性能统计数据都有其生效时段，在MIB库中存储时，可以为每条数据增加一个主键索引字段——开始时间，用于标识该条记录生效时段的开始时间。
图10是根据本发明实施例的性能统计数据采集MIB库模型，图11是根据本发明实施例的性能统计数据采集活动流程，下面结合图10、11对本发明的实施例进行阐述。
SNMP协议MIB定义
MIB的定义可以参见图10，包括过期数据采集的开始时间、结束时间、采集对象标识、过期数据老化时间以及过期性能统计数据存储表。
startRecTime：数据采集开始时间，在本发明实施例中，该数据补采开始时间可以采用整数类型，其值可以为数据采集开始时间到1994年1月1日的秒数。
endRecTime：数据采集结束时间，在本发明实施例中，该数据补采结束时间可以采用整数类型，其值可以为数据采集结束时间到1994年1月1日的秒数。
expireRecTime：老化时间，在本发明实施例中，该老化时间可以采用整数类型，其值可以为老化时间到1994年1月1日的秒数。被管设备在完成过期数据采集后，设置老化时间，老化时间推荐为当前时间延后一小时。expireRecTime同时被借用为采集活动的控制节点，网管侧将该值设置为1，表示启动采集活动；网管侧将该值设置为0，表示强制老化过期数据；网管侧在下达采集命令后，对该值进行检测，如果该值大于当前时间，认为被管设备的采集活动完成。
indexRecGroup：采集对象标识，采集对象，都有对应的标识，如果采集对象中采集指标过多，可以根据需要分配多个采集对象标识。
statRecValueTable：过期性能统计数据存储表，网管通过expireRecTime确认被管设备采集活动完成后，启动网管过期数据采集，解析后存入网管数据库。
采集参数生成
网管通过SNMP SET命令设置startRecTime、endRecTime和indexRecGroup完成采集参数生成。最后通过SNMP SET命令设置expireRecTim值为1激活网元侧过期性能统计数据采集。
被管设备过期性能统计数据采集
被管设备通过startRecTime、endRecTime和indexRecGroup节点解析出采集开始时间、采集结束时间和采集对象，对该采集对象预制的采集模板进行实例化，以SQL或者存储过程从数据库中采集过期数据，并存入过期数据专用存储MIB库。
网管过期性能统计数据采集
网管侧在下达采集命令后，对expireRecTime进行检测，如果该值大于当前时间，认为被管设备的采集活动完成，从而可以从该过期数据专用存储MIB库中采集过期统计数据，解析后存入网管数据库。考虑到被管设备采集活动所需时间具有不确定性，网管可以间隔一分钟检测一次，如尝试两次后采集活动仍然没有结束，认为采集活动异常。
过期数据老化
网管采集完过期数据后，通过SNMP SET命令设置expireRecTim值为0，驱动被管设备对过期数据专用存储MIB库进行老化操作，释放本次采集活动产生的过期性能统计数据表，释放消耗的资源。如果网管没有驱动被管设备进行数据老化操作，被管设备会在到达数据老化时间后，自动进行老化操作。该老化操作可以是，删除过期数据专用存储MIB库中存储的过期数据，释放该MIB库的内存。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业实用性
如上所述，通过上述实施例及优选实施方式，解决了相关技术中存在的无法对较长时段的过期数据进行统计的问题，进而达到了能够实现对网元侧较长时段的过期数据的采集，保证了网管和网元侧设备之间性能统计指标一致性的效果。
