Description

告警信息关联方法、装置、电子设备和可读存储介质

技术领域
本公开涉及网络监控技术领域,尤其涉及一种告警信息关联方法、装置、电子设备和计算机可读存储介质。
背景技术
通信网络规模庞大,结构复杂,设备多种多样,各种硬件部件和软件模块每天产生大量的告警信息。告警风暴如果不加处理,会使告警监测人员频繁收到大量纷杂的告警信息,告警监测人员往往只能依据经验从海量告警中提取有效信息,其问题根源确定准确性难以保证,问题的快速收敛和修复难以保证。
相关技术中,通过设置告警关联,对告警信息进行过滤、合并和关联,以将纷杂信息过滤,将重复信息合并,将问题发生的关联关系直接展示给监测人员。但是目前采用的告警关联监控方案还存在以下缺陷:
(1)目前的告警关联方案由于依赖频繁访问数据库,导致告警关联分析周期长,告警产出慢,计算量大。
(2)目前的告警关联方式主要还是某一告警只和另一告警集合关联,而实际上某一告警可能和多重告警集合相关联,导致目前的告警关联方案无法反映现实场景的复杂性。

下面结合附图对本公开示例实施方式进行详细说明。
如图1所示,终端和/或服务器执行告警信息关联方法,包括以下步骤:
步骤S102,在采集到告警信息时,对告警信息进行向量化处理,得到告警向量。
其中,在短时间内***产生的告警风暴中包含大量的告警信息,这些信息有的是由某种共同因素引发,互相之间存在一定的关联,有的也可能没有任何关系。因此需要执行告警关联操作,以找到这些信息之间的关联关系。
具体地,通过解析实时接收到的告警信息所描述的告警事件、告警信息的发生时间和持续时长,对告警事件进行抽象向量表述,得到告警信息的抽象向量,通过对抽象向量、发生时间和持续时长进行拼接,得到告警向量。
步骤S104,基于告警向量表示的告警事件,在告警关联概率模型集合中获取与告警向量匹配的告警关联模型。
其中,通过预先训练生成多个告警关联模型,并将这多个告警关联模型作为一个告警关联概率模型集合。在基于实时接收到的告警信息生成告警向量后,在告警关联概率模型集合中寻找与该告警向量匹配的告警关联模型,以基于告警关联模型建立告警信息与其它信息之间的关联关系。
步骤S106,获取告警向量的多个告警关联信息,根据告警关联模型建立告警向量与多个告警关联信息之间的关联关系。
其中,为了得到当前采集到的告警信息的实际告警关联信息以及实际关联关系,需要获取可能与告警向量具有关联关系的多个告警关联信息,从而根据告警关联模型建立告警向量和告警关联信息之间的关联关系。
比如,告警信息可以包括PIM(Physical Infrastructure Manager,物理基础设施管理器)告警、VIM(文本编辑器)告警和VNF(虚拟网络功能)告警,当VNF发生告警时,EMS(单元管理***)上报给VFVO告警数据时,需要提供发生告警的VNF 对应的VIM层虚机的通用唯一识别码UUID(Universally Unique Identifier),VIM层的告警通过北向接口报给给NFVO时,也会携带虚机的UUID,因此可以保证发生告警的VNF通过VIM层虚机的UUID与VIM层进行关联。PIM通过北向接口向NFVO报告物理设备告警时,会携带物理设备的设备序列号,VIM层告警通过北向接口报告给NFVO时,根据告警数据携带的虚机UUID,NFVO可以知道该告警位于哪一台计算节点上,而且NFVO预先存储有每一个计算节点对应的物理设备的设备序列号,根据该设备序列号和告警数据携带的虚机UUID,可以将VIM告警与PIM告警关联。基于这些已知的关联方式,得到告警信息的多个告警关联信息,以进一步基于告警关联模型建立告警信息和告警关联信息之间的关联关系。
步骤S108,根据关联关系生成告警关联树,将告警关联树推送给监测终端。
其中,通过将关联关系以告警关联树的方式推送给监测终端,能够便于监测人员看到逻辑结构清晰的告警关联情况。
在该实施例中,通过将实时采集到的告警信息转化为告警向量的形式,以在预存的告警关联概率模型集合中获取与告警向量匹配的告警关联模型,并通过告警关联模型建立告警信息和告警关联信息之间的关联关系,进一步,将关联关系以告警关联树的形式推送给监测终端,一方面,通过设置告警关联概率模型集合,并将告警关联概率模型集合预存在内存中,能够减少IO次数,并能够进一步降低关联过程的资源消耗,提高告警关联树的配置速率,另一方面,通过基于实时采集到的告警信息,能够实时生成告警关联树,有利于提升告警监测体验和告警响应时效。
进一步地,告警关联模型是基于对大量历史告警数据进行分析生成的,因此能够较准确地反应出告警信息和多个告警关联信息之间的关联关系,也就是说可以生成多个告警关联,进而给监测人员提供多条基于告警关联的验证路径,从而能够有效地利用告警关联信息查询告警原因,有利于提高告警根因分析和故障定位效率,辅助运维人员的决策分析,提升业务运行的稳定性。
如图2所示,在本公开的一个实施例中,在步骤S102,采集到告警信息时,对告警信息进行向量化处理,得到告警向量之前,基于历史告警数据生成告警关联模型,具体地,告警关联方法还包括:
步骤S202,获取处于时间戳范围内的历史告警数据。
具体地,所有的历史告警数据集合采用式(1)表示:
W={w 1,...,w i,...,w n}     (1)
n为存量告警数量;w i为第i个告警数据,i∈[1,n]。
获取时间戳范围内的[T s,T e]的存量告警数据集合采用式(2)表示:
Figure PCTCN2021140396-appb-000001
w j为第j个历史告警数据,j∈[1,m],
T s为时间戳范围的下限,T e为时间戳范围的上限,m为时间戳范围[T s,T e]中历史告警 数据w的数量。
通常T s和T e的选取和具体业务情况有较大关系,选择合适的T s和T e能有效降低基于存量数据构建告警关联模型的开销。比如T e取当前时间前一天的零点,T s取T e30天之前的零点。
步骤S204,对历史告警数据集合进行向量化处理,得到向量化告警数据。
其中,通过将历史告警数据进行向量化处理,以通过向量描述出历史告警数据中的事件类型、历史发生时间和持续时长等,进而基于向量化告警数据去探寻不同历史告警数据之间的关联关系,以基于这些关联关系构建出多个告警关联模型,并进一步基于多个告警关联模型构建出告警关联概率模型集合W V
步骤S206,对向量化告警数据进行关联性分组处理,得到分组告警数据。
具体地,对向量化告警数据集合W V进行关联性分组,基于对W V的数据分析配合日常报警登记和梳理进行,得到分组告警数据集合G,如式(3)所示,将具有关联性的向量化告警数据合并到一组W Vi中,如式(4)所示。
G={W V1,...,W Vi,...,W Vx}    (3)
W Vi={w v1,...,w vj,...,w vy}    (4)
其中,x<<m,y<<m,i∈[1,x],j∈[1,y];

特别的,对于任意GS.W Vi,其中的向量化告警的向量结果w v.v不重复。下面对对每一组分组告警数据W Vi进行压缩操作的过程进行详细描述。
对G.W Vi进行压缩的主要方法是对进行告警向量w v合并,具体合并方法为如果G.W Vi中任意两个告警向量w va(对应于第一分组告警数据)和w vb(对应于第二分组告警数据)满足w va.v=w vb.v,则操作对w va和w vb做合并操作得到新的告警向量w vc,记为告警向量压缩,表示为式(14)。
w va,w vb→w vc    (14)
如图4所示,在本公开的一个实施例中,将第一分组告警数据和第二分组告警数 据合并为第三分组告警数据的一种具体实现方式,包括:
步骤S402,将第一分组告警数据和第二分组告警数据中较早的历史发生时间确定为第三分组告警数据的历史发生时间。
步骤S404,确定第一分组告警数据和第二分组告警数据中结束较晚的时刻信息。
步骤S406,根据结束较晚的时刻信息和第三分组告警数据的历史发生时间,确定第三分组告警数据的历史持续时间。
步骤S408,根据相同的抽象向量、第三分组告警数据的历史发生时间和第三分组告警数据的历史持续时间,生成第三分组告警数据,并删除第一分组告警数据和第二分组告警数据。
具体地,合并的具体操作过程如式(15)至式(17)所示。
w vc.v=w va.v    (15)
w vc.t=min(w va.t,w vb.t)    (16)
w vc.d=max(w va.t+w va.d,w vb.t+w va.d)-w vc.t     (17)
在对G.W Vi中所有满足实施w va,w vb→w vc条件的告警向量w v进行向量压缩后,得到压缩后的告警向量子集GS.W Vi。最终得到精简分组数据集合GS。
如图5所示,在本公开的一个实施例中,步骤S210,对精简分组数据进行标准化处理,得到标准化告警样本的一种具体实现方式包括:
步骤S502,根据告警事件的最晚结束事件和最早开始时间,计算对应的精简分组数据的影响时长。
步骤S504,对告警事件的发生时间进行排序,得到时间排序序列。
步骤S506,对时间排序序列进行去重操作,对去重操作后的时间排序序列进行计数,得到告警事件的畸变次数。
步骤S508,根据影响时长配置告警时长阈值,根据畸变次数配置畸变次数阈值。
步骤S510,根据告警时长阈值和/或畸变次数阈值对精简分组数据进行过滤,将过滤后的精简分组数据确定为标准化告警样本。
其中,精简分组数据集合GS进行标准化处理,得到标准化告警样本集合G std,如式(18)所示。
G std={W V1,...,W Vi,...,W Vn}    (18)
其中,n≤count(GS),i∈[1,n]。
具体地,首先,计算W Vi的影响时长du i,如式(19)所示。
du=max(w v.t+w v.d)-min(w v.t)    (19)
上式中,max(w v.t+w v.d)表示获取W Vi中w v结束时间最晚的时刻,min(w v.t)表示获取W Vi中w v最早的开始时间的时刻,两者的差值即为W Vi的影响时长du i,对GS整体处理后得到告警组时长集合DU,如式(20)所示。
DU={du 1,...,du i,...,du c}      (20)
其中,i∈[1,c]。
然后,计算W Vi的畸变次数ch i,如式(21)所示。
ch=count(unique(sort(w v.t)))      (21)
其中,sort(w v.t)表示对W Vi中所有w v的发生时间w v.t进行从小到大排序,unique表示对排序后的结果进行去重,count表示对去重后的结果进行计数,最终得到的计数值就为畸变次数。在对GS整体处理后得到告警组畸变统计集合CH,如式(22)所示。
CH={ch 1,...,ch i,...,ch c}     (22)
其中,i∈[1,c]。
结合实际情况和专家意见,选取合适的告警时长阈值du d和畸变次数阈值ch d对GS进行过滤,降低边缘数据对最终告警概率模型的干扰。
具体地,令du d从1开始逐渐增加,使得P(du d>du i)>0.9,得到目标du d。令ch d从1开始逐渐增加,使得P(ch d>ch i)>0.9,得到目标ch d。最后过滤掉GS中,du>du d,或ch>ch d的W Vi,得到新的G std,如式(23)所示。

步骤S704,统计抽象向量在关联抽象向量之后发生的概率。
步骤S706,根据概率和关联抽象向量生成抽象向量的告警关联模型。
步骤7,基于M推导关联抽象向量集合V的告警关联概率模型集合P,如式(26)所示。
P={p(v i|v j)}     (26)
其中,i∈[1,k],j∈[1,k],i≠j,p(v i|v j)表示告警向量v j发生时,v i发生的概率。
具体地,根据M,可以统计出基于样本集合G std的每个不同告警向量v i关联v j的数量列表,记为c i,如式(27)所示。
c i={count(v i|v j)}      (27)
其中,i∈[1,k],j∈[1,k],i≠j,count(v i|v j)表示v j发生后,v i随后发生的统计和。由此可以得到式(28),即告警关联模型,由多个p(v i|v j)构成告警关联概率模型集合P。
