Description

一种网元管理系统中告警过滤方法及装置 技术领域
本发明涉及网元管理技术, 尤其涉及一种网元管理系统中告警过滤方 法及装置。 背景技术
随着通信技术的迅速发展, 通信网络中各种网元设备也越来越多, 为 此, 需要有一套网元管理系统(EMS, Element Management System )来管 理这些设备, 采集这些设备的故障信息, 并呈现在统一的告警管理界面上。
一般网元管理系统的告警管理界面是一个告警数据列表界面, EMS实 时把设备上采集上来的告警数据放在列表界面中供用户查看。 但是随着通 信网规模的扩大, 整个告警系统中的当前告警数量已经由以前的最大容纳 几千个告警扩展到现在动辄要求容纳十几万到几十万个告警, 这种情况下, 用户迫切需要一种过滤方法来快速从海量告警中检索出自己需要的数据。
一般 EMS的过滤操作都是需要用户通过点击查询条件设置打开一个条 件设置窗口, 然后用户在条件设置窗口中输入网元位置、 告警码、 告警级 另 |J、 告警文本等信息, 然后系统再把满足过滤条件的告警数据放到列表界 面中供用户查看。 但是, 这样一个系统操作设置复杂, 对用户要求也比较 高。 同时, 由于现在的网络环境复杂, 多种设备并存, 因此不同设备可能 使用不同告警属性字段来表达相似的信息, 比如,为表达某告警和"高新区" 相关,一些设备上报告警时会把这个信息保存在告警的 "影响网元"属性字段 中,另一些设备可能会在上报时把这个信息保存在告警的"业务对象"属性字 段中, 还有些设备可能又使用的其他的自定义属性字段, 这种情况下, 使 用传统方法设置查询条件将包含相似信息的告警都过滤出来是一件非常麻 烦的事。 发明内容
有鉴于此, 本发明实施例希望提供一种网元管理系统中告警过滤方法 及装置, 至少能够在与告警列表处于同一显示界面的文本搜索框中获取用 户输入的查询字符序列, 并在本地缓存的告警数据中进行告警过滤。

本发明实施例提供了一种网元管理系统中告警过滤的方法和装置, 在 显示界面上设置文本搜索框和告警列表, 客户端在文本搜索框中获取用户 输入的字符序列, 对所述字符序列进行拆分及解析, 根据解析结果过滤缓 存在本地的告警数据, 将过滤后的告警数据实时显示到告警列表; 如此, 能够在与告警列表处于同一显示界面的文本搜索框中获取用户输入的查询 字符序列, 并在本地缓存的告警数据中进行告警过滤来提高过滤效率, 大 大提高用户的体验, 还可以通过更改字符序列来不断修正过滤结果, 更加 灵活方便。 在网络环境复杂, 多种设备并存, 不同设备使用不同告警属性 字段上报相似告警信息的情况下, 与需要用户指定查询属性字段的传统设 置查询条件的方法相比, 用户只需要输入关键词, 系统就可以将包含所述 关键词的所有告警数据都过滤出来。 附图说明
图 1为本发明实现网元管理系统中告警过滤方法的流程示意图; 图 2为本发明实现网元管理系统中显示界面示意图;
图 3为本发明实现网元管理系统中一种告警过滤装置的结构示意图; 图 4为本发明实现网元管理系统中另一种告警过滤装置的结构示意图。 具体实施方式
本发明实施例中, 在显示界面上设置文本搜索框和告警列表, 客户端 在文本搜索框中获取用户输入的字符序列, 对所述字符序列进行拆分及解 析, 根据解析结果过滤缓存在本地的告警数据, 将过滤后的告警数据实时 显示到告警列表。
下面通过附图及具体实施例对本发明做进一步的详细说明。
本发明实现一种网元管理系统中告警过滤的方法, 如图 1 所示, 该方 法包括以下几个步骤:
步骤 101 : 在显示界面上设置文本搜索框和告警列表;
例如, 对于 Visual C++而言, 设置文本框的方法为在显示界面上创建 CEdit控件, 设置告警列表的方法为在显示界面上创建 ListBox控件;
图 2给出了一种显示界面上设置文本搜索框和告警列表的示意图, 如 图 2所示, 搜索框在显示界面的上方, 告警列表在显示界面的下方。
步骤 102: 客户端在文本搜索框中获取用户输入的字符序列;
如图 2所示, 文本搜索框右侧设置搜索按 , 当用户点击搜索按 后, 客户端获取用户输入; 显示界面上也可以不设置搜索按鈕, 客户端实时获 取用户输入;
步骤 103: 对输入的字符序列进行拆分及解析;
具体的, 根据拆分规则将输入的字符序列拆分成至少一个关键词, 根 据解析规则对拆分出的关键词进行解析;
其中, 所述拆分规则为: 使用空格和 /或拆分符号进行关键词的拆分; 所述拆分符号为前后默引号""。
当输入字符序列不包含拆分符号时, 例如, 输入字符序列 "高新区 严 重 未确认", 根据拆分规则拆分出的关键词为: "高新区"、 "严重"、 "未确 认";
当输入字符序列包含拆分符号时, 拆分符号之间的子字符序列作为关 键词,再将剩余部分使用空格进行拆分,例如,输入字符序列 "2013-07-10 " 小区 a"严重", 根据拆分规则拆分出的关键词为: "2013-07-10"、 "小区 a"、 "严重"。 另外, 当拆分符号之前符号为转义符号时, 表示使用拆分符号本身进 行过滤, 即拆分符号不起拆分作用;
所述转义符号为\。
例如, 输入字符序列 "\\ \" \# \"", 根据拆分规则拆分出的关键词为: "\\"、 "\""、 "\#"、 "\""。
为清晰起见, 本发明中提及的输入字符序列均包含在一对全角默引号 中, 实际输入不需要这一对全角默引号, 本发明中举例的关键词都用一对 全角默引号区分开, 实际的关键词并没有这一对全角默引号。
其中, 所述解析规则包括:
当拆分出的关键词中包含转义符号时, 根据起转义作用的转义符号解 析出基本关键词;
当拆分后的关键词以语义符号开始时, 根据语义符号解析出语义词; 当拆分出的关键词不包含转义符号和语义符号时, 直接将所述关键词 作为基本关键词。
所述基本关键词为拆分后不包含转义符号或语义符号的关键词; 所述语义符号为#;
所述语义词包括:
表示特定告警属性的语义词, 如 "#sw:,, 代表告警级别, "#pos:,, 代表 告警位置, "#txt:,, 代表告警附加文本等;
表示 "否" 关系的语义词, 如 "#! : ", 此语义词与表示特定告警属性的 关键词连用;
表示全局 "或" 关系的语义词, 如 "#global:or", 此语义词独立出现, 代表本组输入经拆分解析后得到的关键词之间为 "或" 关系;
表示业务动作的语义词, 如 "#mml:", 代表系统除了执行查询过滤以 外还需要执行一次业务动作, 动作的种类由具体的 mml命令决定。 例如, 输入字符序列为 "\\ \" \# \"", 根据拆分规则拆分出的关键词为: "\\"、 "\""、 "\#"、 "\"",根据起转义作用的转义符号解析出基本关键词为:
"\" """ """ . 例如, 输入字符序列为 "#svr:普通 I严重 #pos:高新区 #txt:链路断", 根 据拆分规则拆分出的关键词为: "#svr:普通 I严重"、 "#pos:高新区"、 "#txt: 链路断", 根据语义符号解析出语义词为表示特定告警属性的语义词, 即分 别为表示告警级别语义词 (#svr:)、 告警位置语义词 (#pos:)、 告警附加文 本语义词 (#txt: );
例如, 输入字符序列为 "高新区 严重 未确认", 根据拆分规则拆分出 的关键词为: "高新区"、 "严重"、 "未确认", 拆分出的关键词不包含转义 符号和语义符号, "高新区"、 "严重"、 "未确认" 为基本关键词。
步骤 104: 根据解析结果过滤缓存在本地的告警数据, 将过滤后的告警 数据实时显示到告警列表。
具体的, 根据解析出的基本关键词按照 "并" 关系进行告警数据过滤, 或者, 按照解析出的语义词进行告警数据过滤, 将满足过滤条件的告警数 据显示在显示界面的告警列表上;
其中, 所述根据解析出的基本关键词按照 "并" 关系进行告警数据过 滤, 具体为: 一条告警所有属性的集合包含解析出的所有基本关键词, 则 本条告警满足过滤条件;
例如, 解析出基本关键词 "高新区"、 "严重"、 "未确认", 则过滤条件 为: 一条告警所有属性的集合包含 "高新区" 和 "严重" 和 "未确认" 三 个关键词;
其中, 所述按照解析出的语义词进行告警数据过滤, 具体为根据语义 词表示的告警属性、 "否" 关系、 全局 "或" 关系进行告警数据过滤, 除了 语义词所表示的关系之外都按照 "并" 关系进行告警数据过滤。 例如, 输入字符序列 "#svr:普通 I严重 #pos:高新区 #txt:链路断", 根据 拆分规则拆分出关键词 "#svr:普通 I严重"、 "#pos:高新区"、 "#txt:链路断", 根据解析规则解析出表示告警级别语义词( #svr: )、告警位置语义词( #pos: )、 告警附加文本语义词 (#txt:), 则过滤条件为: 一条告警的告警级别属性包 含 "普通" 或 "严重" 关键词, 并且告警位置属性包含 "高新区" 关键词, 并且告警附加文本属性包含 "链路断" 关键词;
例如, 输入字符序列 "#! :#svr:普通 I严重", 根据拆分规则拆分出关键词 "#! :#svr:普通 I严重", 根据解析规则解析出表示 "否" 关系语义词 ( #!: )、 表示告警级别语义词 (#svr:), 则过滤条件为: 一条告警的告警级别属性不 能包含 "普通" 或 "严重" 关键词;
例如, 输入字符序列 "#global:or 高新区 严重", 根据拆分规则拆分出 关键词 "#global:or"、 "高新区"、 "严重", 根据解析规则解析出全局 "或" 关系语义词 ( #global:or )、 基本语义词 "高新区"、 "严重", 则过滤条件为: 一条告警所有属性的集合包含 "高新区" 或者 "严重" 关键词。
其中, 根据过滤条件在告警数据中进行过滤属于现有技术;
因为告警数据可以达到几十万条甚至更多, 所以需要考虑告警过滤效 率, 本发明使用本地缓存告警数据的方式提高过滤效率;
其中, 所述本地缓存告警数据为本地实时获取并保存远端存储器中所 存储的网元管理系统中的告警数据, 所述远端存储器可以为服务端存储器; 本步骤还包括: 当本地缓存的告警数据发生变化时, 可以实时更新显 示满足过滤条件的告警数据。
如表示业务动作的语义词所述, 上述方法还包括: 对输入字符序列进 行拆分解析后, 根据解析结果执行相应的操作;
具体的, 根据拆分规则将输入的字符序列拆分成至少一个关键词, 根 据解析规则对拆分出的关键词进行解析, 根据解析结果过滤缓存在本地的 告警数据, 过滤后执行相应的操作;
例如, 输入字符序列 "#mml:export=c:\export.csv 高新区",才艮据拆分规 则拆分出关键词 "#mml:export=c:\export.csv"、 "高新区", 才艮据解析规则解 析出业务动作语义词 (#mml )、 基本语义词 "高新区", 则过滤条件为: 一 条告警所有属性的集合包含 "高新区" 关键词; 并且在过滤后执行告警表 格导出动作, 导出的告警数据以 csv格式保存在文件 c:\export.csv中;
例如, 输入字符序列 "#mml:print 高新区", 根据拆分规则拆分出关键 词 #mml:print", "高新区", 根据解析规则解析出业务动作语义词 (#mml )、 基本关键词 "高新区", 则过滤条件为: 一条告警所有属性的集合包含 "高 新区" 关键词; 并且在过滤后执行告警表格的打印动作。
为了实现上述方法, 本发明还提供一种网元管理系统中告警过滤的装 置, 如图 3所示, 该装置位于客户端包括: 显示界面 31、 告警数据缓存单 元 32、 拆分解析单元 33、 过滤单元 34; 其中,

另外, 当拆分符号之前符号为转义符号时, 表示使用拆分符号本身进 行过滤, 即拆分符号不起拆分作用;
所述转义符号为\。
例如, 输入字符序列 "\\ \" \# \"", 根据拆分规则拆分出的关键词为: "\\"、 "\""、 "\#"、 "\""。
为清晰起见, 本发明中提及的输入字符序列均包含在一对全角默引号 中, 实际输入不需要这一对全角默引号, 本发明中举例的关键词都用一对 全角默引号区分开, 实际的关键词并没有这一对全角默引号。
其中, 所述解析规则包括:
当拆分出的关键词中包含转义符号时, 根据起转义作用的转义符号解 析出基本关键词; 当拆分后的关键词以语义符号开始时, 根据语义符号解析出语义词; 当拆分出的关键词不包含转义符号和语义符号时, 直接将所述关键词 作为基本关键词。

表示业务动作的语义词, 如 "#mml:", 代表系统除了执行查询过滤以 外还需要执行一次业务动作, 动作的种类由具体的 mml命令决定。
例如, 输入字符序列为 "\\ \" \# \"", 根据拆分规则拆分出的关键词为: "\\"、 "\""、 "\#"、 "\"",根据起转义作用的转义符号解析出基本关键词为:
"\,, """ """ . 例如, 输入字符序列为 "#svr:普通 I严重 #pos:高新区 #txt:链路断", 根 据拆分规则拆分出的关键词为: "#svr:普通 I严重"、 "#pos:高新区"、 "#txt: 链路断", 根据语义符号解析出语义词为表示特定告警属性的语义词, 即分 别为表示告警级别语义词 (#svr:)、 告警位置语义词 (#pos:)、 告警附加文 本语义词 (#txt: );
例如, 输入字符序列为 "高新区 严重 未确认", 根据拆分规则拆分出 的关键词为: "高新区"、 "严重"、 "未确认", 拆分出的关键词不包含转义 符号和语义符号, "高新区"、 "严重"、 "未确认" 为基本关键词。 所述过滤单元 34,具体配置为根据拆分解析单元 33解析出的基本关键 词按照 "并" 关系进行告警数据过滤, 或者, 按照解析出的语义词进行告 警数据过滤, 将满足过滤条件的告警数据发送至显示单元 312进行显示; 其中, 所述根据解析出的基本关键词按照 "并" 关系进行告警数据过 滤, 具体为: 一条告警所有属性的集合包含解析出的所有基本关键词, 则 本条告警满足过滤条件;
