Description

性能阈值监控处理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种性能阈值监控处理方法及装置。
背景技术
在移动通信网络中，运营商通过性能测量数据的分析来评估网络质量和网络或服务资源的利用率以及网络的处理能力，也可以通过对性能数据进行阈值监控以及时掌握网络的运营情况，当性能测量值超过该测量预设的阈值时，会上报相应包含性能告警的通知给运营商，这样运营商可以及时采取相应的措施防止网络出现严重故障甚至瘫痪。
当网络功能虚拟化后，网络管理架构和机制都有一些变化，图1是相关技术中的网络功能虚拟化后的管理架构图，如图1所示，其中：网络功能虚拟化编排器(Network Functions Virtualization Orchestrator，简称为NFVO)负责网络服务的生命周期管理、跨虚拟基础设施管理者(Virtualised Infrastructure Manager，简称为VIM)的网络功能虚拟化基础设施(Network Functions Virtualization Infrastructure，简称为NFVI)资源调度等功能。虚拟网络功能管理者(Virtual Network Functions Manager，简称为VNFM)负责VNF的生命周期管理，每个VNF都有一个关联的VNFM。VIM负责控制和管理NFVI计算、存储和网络资源。VNF的生命周期内有伸缩操作包括扩展操作(Scale out/up)和收缩操作(Scale in/down)，可以调整VNF的虚拟资源。
传统网管多采用包含网络管理(Network Management，简称为NM)或运营支撑***(Operation Support System，简称为OSS)、网元管理(Element Management，简称为EM)和网元的三层管理结构。其中，NM也称为网络管理***(Network Management System，简称为NMS)，EM也可称为网元管理***(Element Management System，简称为EMS)。OSS/NM和EM之间的接口是北向接口，EM和网元之间是南向接口。EM完成网元的配置和网元性能、故障、告警等信息的采集。NM面向全网的网络监视和分析，功能包括网络拓扑的监视与操作、全网故障告警与受理、全网配置信息的采集与配置分发、端到端网络性能监测与分析、流量流向与流量分布的监测与分析等。在网络功能虚拟化后，传统网管负责虚拟网络功能应用层的管理。
传统网络中网元的处理能力是固定的，对于可以用来衡量网元性能的指标，表示该网元的性能处理能力快饱和或缺乏的阈值也相对是固定的，但是当网络功能虚拟化后，基于VNF的网元在生命周期内会被扩展或收缩来调整其可以使用的虚拟资源，可使用的虚拟资源的变化会导致基于VNF的网元对业务的处理能力发生变化。如果性能阈值监控阈值不进行及时的调整，那么NM接收的性能告警将不能正确的反映当前网络的性能状况甚至误导运营商，因为性能告警的等级可能过于严重或偏轻，性能告警的数量可能过多或偏少。
针对相关技术中存在的当VNF缩扩容后，NM接收的性能告警无法正确的反映当前网络的性能状况的问题，目前尚未提出有效的解决方案。

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。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种性能阈值监控处理方法，图2是根据本发明实施例的第一种性能阈值监控处理方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，网络管理NM在接收到虚拟网络功能VNF扩展或VNF收缩完成消息后，判定是否要更新基于VNF的网元的当前性能阈值监控里被监控性能测量项的当前监控阈值；
步骤S204，当判定结果为需要更新所述当前监控阈值时，所述NM确定被监控性能测量项的新的监控阈值；
步骤S206，所述NM向网元管理EM发送携带所述新的监控阈值的消息，其中，所述消息用于请求所述EM根据所述新的监控阈值对所述被监控性能测量项进行监控。
其中，上述实施例中的动作执行者除了是NM外，还可以是网络运营支撑***(Operation-Support System，简称为OSS)。
从上述实施例可知，NM可以根据VNF扩展或VNF收缩的情况动态调整监控阈值，即，确定上述的新的监控阈值，从而使得EM按照准确的监控阈值对网元的性能进行监控，保证虚拟化后性能阈值监控能正确的反应当前网络的性能状态，解决了相关技术中存在的当VNF 缩扩容后，NM接收的性能告警无法正确的反映当前网络的性能状况的问题，进而达到了准确的监控当前网络性能状况的效果。
在一个可选的实施例中，上述NM接收到上述VNF扩展或VNF收缩完成消息的方式可以有多种，例如，可以接收来自EM和/或网络功能虚拟化编排器NFVO的指示上述VNF扩展或VNF收缩完成的消息。需要说明的是，上述的接收方式仅是示例，还可以采用其他的方式接收指示VNF扩展或VNF收缩完成的消息。
在一个可选的实施例中，NM判定是否要更新基于VNF的网元的当前性能阈值监控里被监控性能测量项的当前监控阈值包括：NM判断VNF扩展或VNF收缩后，上述网元的被监控测量项对应的业务处理能力(该业务处理能力也可称为业务指标)是否发生变化；在确定该业务处理能力发生变化的情况下，确定需要更新当前监控阈值；在确定该业务处理能力未发生变化的情况下，确定不需要更新当前监控阈值；当确定需要更新监控阈值时，可以通过如下方式进行更新：上述NM根据业务处理能力与监控阈值之间的关系以及变化后的业务处理能力确定上述新的监控阈值。在该实施例中，网元的被监控测量项对应的业务处理能力和监控阈值是满足一定的对应关系的，当网元的被监控测量项对应的业务处理能力改变后，对该网元进行监控的监控阈值也需要进行相应的调整，以适应改变后的业务处理能力。
在一个可选的实施例中，上述NM向EM发送携带新的监控阈值的消息包括：NM向EM发送第一请求消息和第二请求消息，其中，该第一请求消息用于请求EM删除原有的性能阈值监控任务，该第二请求消息中携带新的监控阈值，该第二请求消息用于请求EM建立与新的监控阈值对应的性能阈值监控任务；或者，该NM向EM发送第三请求消息，其中，该第三请求消息中携带新的监控阈值，该第三请求消息用于请求EM按照新的监控阈值修改原有的性能阈值监控任务的监控阈值。其中，上述的向EM发送第一请求消息和第二请求消息时，可以先发送第一请求消息，再发送第二请求消息，也可以先发送第二请求消息，再发送第一请求消息，也可以同时发送第一请求消息和第二请求消息。
在本实施例中还提供了一种性能阈值监控处理方法，图3是根据本发明实施例的第二种性能阈值监控处理方法的流程图，如图3所示，该流程包括如下步骤：
步骤S302，网元管理EM接收来自网络管理NM的携带新的监控阈值的消息，其中，该新的监控阈值为NM在接收到虚拟网络功能VNF扩展或VNF收缩完成消息，且判定要更新基于VNF的网元的当前性能阈值监控里被监控性能测量项的当前监控阈值后所确定的更新阈值；
步骤S304，该EM根据上述新的监控阈值对被监控性能测量项进行监控。
其中，上述实施例中的NM还可以替换为OSS。在上述实施例中，EM可以根据NM发送的新的监控阈值对被监控性能测量项进行监控，且该新的监控阈值是NM根据VNF缩扩容完成后重新确定的。从而保证虚拟化后性能阈值监控能正确的反应当前网络的性能状态，解决了相关技术中存在的当VNF缩扩容后，NM接收的性能告警无法正确的反映当前网络的性能状况的问题，进而达到了准确的监控当前网络性能状况的效果。
在一个可选的实施例中，上述EM在接收来自上述NM的携带上述新的监控阈值的消息之前，上述方法还包括：EM接收来自虚拟网络功能管理者VNFM的用于指示上述VNF扩展或VNF收缩完成的通知消息；该EM根据上述通知消息向NM发送指示上述VNF扩展或VNF收缩完成的消息。在该实施例中，监控阈值的修改可以是由EM触发的。在实际应用中，处理可以由EM触发外，还可以由NFVO触发，即，NFVO在确定VNF扩展或收缩完成后，向NM发送上述处理消息。
在一个可选的实施例中，上述EM接收来自上述NM的携带上述新的监控阈值的消息包括：EM接收来自NM的第一请求消息和第二请求消息，其中，该第二请求消息中携带上述新的监控阈值；上述EM根据上述新的监控阈值对被监控性能测量项进行监控包括：EM根据上述第一请求消息删除原有的性能阈值监控任务，并根据上述第二请求消息建立与新的监控阈值对应的新的性能阈值监控任务。其中，上述的接收来自NM的第一请求消息和第二请求消息时，可以先接收第一请求消息，再接收第二请求消息，也可以先接收第二请求消息，再接收第一请求消息，也可以同时接收第一请求消息和第二请求消息。
在一个可选的实施例中，上述EM接收来自上述NM的携带新的监控阈值的消息包括：上述EM接收来自上述NM的第三请求消息，其中，该第三请求消息中携带上述新的监控阈值；上述EM根据上述新的监控阈值对被监控性能测量项进行监控包括：EM根据上述第三请求消息按照新的监控阈值修改原有的性能阈值监控任务的监控阈值。其中，EM判定被监控性能测量值是否超过或达到新的监控阈值，当超过或达到时，EM发送性能告警通知给NM。

步骤S506，NM发现VNF扩展或收缩后被监控性能测量项对应的业务处理能力(也可以称为业务指标)发生了变化，判定是否需要修改当前被监控性能测量项的监控阈值(即，当前监控阈值)；
步骤S508，当判定结果为需要修改当前的监控阈值时，NM根据业务处理能力与监控阈值之间的关系以及新的业务处理能力值确定被监控性能测量项的新的监控阈值；
步骤S510，NM给EM发送请求消息(对应于上述的第三请求消息)，以指示EM修改现有性能阈值监控任务里被监控性能测量项的监控阈值，该请求消息中携带新的监控阈值；
步骤S512，EM修改性能阈值监控任务里被监控性能测量项的监控阈值并根据新的监控阈值对基于虚拟网络功能(VNF)的网元进行性能阈值监控；EM在修改监控阈值前可先将相应的性能阈值监控任务暂停，待监控阈值被修改完成之后，再恢复该性能阈值监控任务，即根据新的监控阈值对基于虚拟网络功能(VNF)的网元进行阈值监控；
步骤S514，EM根据监控时间间隔获取基于VNF的网元上报的性能测量值；
步骤S516，EM判定被监控性能测量值是否越过或达到新的监控阈值；
步骤S518，当判定结果为超过或达到新的监控阈值时，EM发送性能告警通知给NM。
实施例二
在该实施例中，由NFVO触发修改用于监控性能的监控阈值。下面结合传统的网元的性能阈值监控流程对本发明进行说明。
图6是根据本发明实施例的NFVO触发的修改监控阈值的流程图，如图6所示，该流程除包括图4所示的流程外，还包括如下步骤：
步骤S602，NFVO向VNFM发送VNF扩展或收缩请求；
步骤S604，VNFM进行VNF收缩或扩展处理；
步骤S606，VNFM告知NFVO VNF扩展或收缩完成；
步骤S608，NM接收到NFVO发送的指示VNF扩展或VNF收缩完成的消息；
步骤S610，NM发现VNF扩展或VNF收缩后被监控测量项对应的业务处理能力发生了变化，判断是否要修改当前性能阈值监控里被监控性能测量项的监控阈值；
步骤S612，在判定结果为被监控性能测量项的监控阈值需要修改时，根据业务处理能力 与监控阈值之间的关系以及新的业务处理能力值确定被监控性能测量项的新的监控阈值；

步骤S622，EM判断被监控性能测量值是否越过或达到新的监控阈值；
步骤S624，当判断结果为超过或达到新的监控阈值时，EM发送性能告警通知给NM。
实施例三
在该实施例中，假设网元虚拟分组数据网络网关(Virtual Packet Data Network Gateway，简称为vPGW)在扩展前每秒能够处理的最大呼叫次数为10000次，扩展后的每秒能够处理的最大呼叫次数为20000次。性能阈值监控阈值和最大呼叫次数的关系为比例值95％，即扩展前对vPGW设置的性能阈值监控阈值(也可简称为监控阈值)为9500。
NM给EM发送创建性能测量任务和性能阈值监控任务的消息，要求测量vPGW的呼叫次数，同时对呼叫次数设置监控任务。
EM给网元vPGW下发性能测量任务对vPGW的呼叫次数进行测量；
vPGW在上报时间点给EM发送的呼叫次数测量值为9500次；
EM判定性能测量值达到监控阈值，EM给NM发送性能告警通知；
EM接受VNFM发送的vPGW Scaled out完成的消息，并给NM发送消息指示vPGW Scale out完成；
NM发现vPGW Scale out后被监控测量项呼叫次数对应的业务处理能力每秒能处理的最大呼叫次数发生了变化，确定呼叫次数的监控阈值需要修改。并根据性能阈值监控阈值和最大呼叫次数的关系为比例值95％以及新的业务处理能力每秒能够处理的最大呼叫次数为20000次确定新的监控阈值为20000*95％＝19000。
NM给EM发送请求消息(对应于上述的第三请求消息)，以修改现有性能阈值监控任务呼叫次数的监控阈值，消息中携带新的监控阈值19000。
EM修改呼叫次数的监控阈值为19000，并根据该新的监控阈值19000对vPGW的呼叫次数进行性能阈值监控。
EM根据监控时间间隔，判定被监控性能测量呼叫次数的值是否达到新的监控阈值19000，当达到时EM发送性能告警通知给NM。
