Description

一种物联网监控方法及系统 技术领域
本发明涉及通信技术领域, 尤其涉及一种物联网监控方法及系统。 背景技术
物联网泛指 "物物相连之网", 其本质和核心仍是互联网, 是指通过射 频识别(RFID )、红外感应器、全球定位系统、激光扫描器等信息传感设备, 按约定的协议, 把任何物体与互联网相连接, 进行信息交换和通信, 以实 现对物体的智能化识别、 定位、 跟踪、 监控和管理的一种网络。 目前, 物 联网作为新一代信息技术的重要一项, 成为国家首批加快培育的七个战略 新兴产业, 并在智能交通、 移动支付、城市管理等领域 RFID与物联网得到 较快的发展。
随着物联网在各种领域广泛应用, 物联网中部署的网络节点越来越多, 设备种类越来越丰富, 整合的技术越来越复杂。 特别是物联网目前主要应 用于智能交通、 门禁、 物流等领域中, 在这些系统和环境中, 数据吞吐量 极大, 因此对物联网的稳定性提出较高的要求。 除了要提高物联网中软件、 硬件设备的质量, 也需要一种技术能及时发现网络中的软硬件设备的运行 异常情况, 减少系统的故障恢复时间, 通知运维人员尽快解决和恢复系统 运行异常。
目前, 业界监控系统分为两种一一 "代理方式" 和 "无代理方式"。 基 于代理方式的监控系统需要在被监控端部署监控软件, 由监控代理采集监 控数据。 而无代理方式的监控系统不需要安装监控代理软件, 在被监控端 只需添加必要的网络协议或少量插件即可, 监控服务器依照约定协议向被 监控端发送监控指令, 并接收被监控端根据监控指令反馈的监控指标值, 这种方式的监控系统主要特点是方便监控端部署, 成本很低, 被监控端资 源占用率较低, 主要用于规模较大的网络环境中。
基于 "代理方式" 的监控系统存在以下不足:
物联网环境中监控资源、 即被监控端和监控服务器端之间有时因为网 络问题而失去连接时, 现有技术中没有具体方案实现断链期间, 对监控资 源的各项监控指标的采集。
另外, 物联网环境中有些资源的监控指标、 数据具有状态类型, 所谓 的状态类型监控数据是指监控项的数值区间只有几种可能, 如状态机一样, 其数值也只能在这几种状态值中变换。 代理端只需监控到这种类型的监控 数据的状态变化, 现有技术中周期性获取状态数据方式无法有效的监测到 监控资源状态的变化。 发明内容
有鉴于此, 本发明提供一种基于代理方式的物联网监控方法及系统, 用于解决现有技术中周期性获取状态数据方式无法有效的监测到监控资源 状态的变化的问题, 保证物联网应用系统的稳定运行。
本发明提供一种物联网监控方法, 包括:
监控代理端读取监控服务器端的连接信息, 通过该监控服务器端连接 信息连接监控服务器端, 并接收监控服务器端返回的监控项配置;
读取监控项配置, 根据该监控项配置中包含的监控项确定对应的监控 项数据采集方式, 应用确定的监控项数据采集方式采集监控资源的监控项 数据, 并将采集到的监控项数据返回监控服务器端。
一种物联网监控系统, 包括监控代理端和监控服务器端:
所述监控代理端, 用于读取监控服务器端的连接信息, 通过该监控服 务器端连接信息连接监控服务器端, 并接收监控服务器端返回的监控项配 置; 读取监控项配置, 根据该监控项配置中包含的监控项确定对应的监控 项数据采集方式, 应用确定的监控项数据采集方式采集监控资源的监控项 数据, 并将采集到的监控项数据返回监控服务器端。
与现有技术相比较, 本发明提供的一种物联网监控方法及系统通过对 物联网中软硬件监控资源的分析及抽象, 本发明中监控代理端采集监控数 据、 即监控项数据时, 提供了主动采集和被动采集两种方式, 可根据监控 资源重要性及监控项接口特点, 选取最佳的监控方式, 从而达到监控代理 减少资源占用和快速发现资源状态变化的效果。 附图说明

图 3 为本发明实施例中采用主动数据采集方式对监控项数据进行采集 的具体流程示意图;

图 6为本发明实施例代理端緩存队列中的监控项数据处理流程示意图; 图 7为本发明实施例一种物联网监控系统的结构示意图。 具体实施方式
本发明实施例提供一种物联网监控方法, 该方法包括: 监控代理端读 取监控服务器端的连接信息, 通过该监控服务器端连接信息连接监控服务 器端, 并接收监控服务器端返回的监控项配置; 读取监控项配置, 根据该 监控项配置中包含的监控项确定对应的监控项数据采集方式, 应用确定的 监控项数据采集方式采集监控资源的监控项数据, 并将采集到的监控项数 据返回监控服务器端。
如图 1 所示, 本发明实施例提供一种物联网监控方法, 在具体的应用 环境中, 本发明实施例的具体实现步驟包括:
本发明监控系统结构整体上由监控服务器端和监控代理端组成, 监控 服务器端与监控代理端在网络环境中通过 HTTP、 Socket等协议连接和通 信。 下面进一步说明监控服务器端和监控代理端内部的组成。
步驟 101 ,监控代理端读取监控服务器端的连接信息, 通过该监控服务 器端连接信息连接监控服务器端, 并接收监控服务器端返回的监控项配置; 本系统的监控对象是物联网环境中部署的各种类型资源, 如 Web服务 器、 应用服务器、 操作系统、 数据库、 RFID阅读器设备等监控资源;
监控资源根据业务需要, 分为各种类型的监控项。 而监控项根据所属 监控资源的类别和建模的需要, 又可划分在不同抽象层次。 例如, 数据库 监控资源在本系统中可分为两层一一数据库服务级别和库表级别。
数据库服务级别的监控项, 例如数据库服务是否可用、 分配锁的数量、 緩存使用情况等监控项的定义是从资源整体角度考虑的。
库表级别, 例如具体某个库事务文件占用空间等监控项则是从资源更 底层角度考虑, 进行更细粒度的划分。
步驟 102,监控代理端读取监控项配置,根据该监控项配置中包含的监 控项确定对应的监控项数据采集方式, 应用确定的监控项数据采集方式采 集监控资源的监控项数据, 其中, 所述监控项数据采集方式包括主动数据 采集方式和被动数据采集方式。
所述根据该监控项配置中包含的监控项确定对应的监控项数据采集方 式, 包括:
当监控项数据是随时间频繁变化的, 则确定与监控项对应的监控项数 当监控项数据为物联网中软硬件资源中具有状态类型特点的监控数 据, 则确定与监控项绑定的监控项数据采集方式为被动数据采集方式。
启动定时任务采集监控项数据, 将监控项数据保存到緩存队列中; 监 控项配置由监控资源清单、 各监控资源的监控项条目及各监控项采集周期 等组成。 监控代理端对各监控项按照配置的采集周期分别执行采集动作, 如调用操作系统指令, 访问外部组件程序接口等。
为了实现断链期间, 对监控资源的各项监控指标的采集, 本发明实施 例还包括步驟 103:
步驟 103 ,监控代理端访问监控代理端通信组件,检查监控代理端与监 控服务器端是否断链; 监控代理端通过周期向监控服务器端发送心跳握手 消息, 维护与监控服务器端的链路。 如果监控代理端与监控服务器端断链, 则返回步驟 102,并检测緩存队列中监控项数据是否达到存储上限,如果是, 则根据预设的规则丟弃或緩存溢出监控项数据, 如果监控代理端与监控服 务器端未断链运行步驟 104。
当监控代理端与监控服务器端长时间断链时, 监控代理端如不进行特 别处理, 緩存队列中数据会越来越多, 导致监控代理端耗用大量资源。 本 发明提出两种解决方法:
方法 1 ,设置緩存队列的存储上限并提供外部配置选项,监控项数据以 先进先出方式入队, 当监控项数据入队时发现已达到存储上限, 则自动丟 弃入队时间最长的数据记录。
方法 2, 设置緩存队列的存储上限的同时, 提供数据外部持久化功能。 与方法 1 在入队达到存储上限直接丟弃不同, 会将入队时间较长的数据记 录持久化到外部存储介质, 如文本文件、 数据库。 在断链恢复后, 再读出 和发送这部分监控项数据。 系统用户可根据监控代理端运行环境及监控项 数据的重要性选取更合适的緩存策略。
步驟 104, 监控代理端定时向监控服务器端发送采集到的监控项数据, 取出緩存队列中的监控项数据, 上报到监控服务器端中的预处理模块。 监 控项数据发送成功后, 清空緩存队列中的数据记录或可能的外部持久化数 据记录。
步驟 105 ,监控服务器端接收到监控代理端发送的监控项数据后, 解析 所述监控项数据将其封装为监控服务器端预定义类型数据; 预定义类型数 据应至少包含监控代理端标识、 监控项标识、 采集数据及采集时间等字段。
步驟 106,监控服务器端中的预处理模块进行是否触发告警的判断, 即 调用数据持久化模块执行查询, 检查监控项数据是否超过查询到的监控阈 值; 如果未超过监控阈值, 则执行步驟 107, 否则执行步驟 108;
步驟 107, 通过数据持久化模块保存封装的预定义类型数据。
步驟 108 ,监控服务器端触发监控服务器端告警,监控服务器端产生告 警消息, 并转交给告警模块。
步驟 109, 告警模块接到告警后, 解析告警消息, 并根据消息类型以配 置的告警处理方式对外部系统发布告警事件, 告警处理方式包括短信、 Email, 界面实时显示等。
网络运维人员得到告警后, 通过监控客户端查询告警和监控项的详细 信息, 此外网络运维人员还可通过监控系统中拓朴、 地理信息等其他模块 丰富的展现方式, 及早定位运行异常的软件或硬件设备, 从而降低物联网 的维护成本, 减少故障恢复时间, 提高系统整体的稳定性。 此外, 告警模 块还提供了业务处理绑定功能, 可根据告警类型, 预先提供相应的解决方 法。 举例来说, 监控代理端监控数据库服务器, 随着数据库操作的增长, 数据库事务日志文件也随着膨胀, 当达到预设的监控阈值时, 监控服务器 端产生日志文件过大的告警事件, 告警模块监听到该告警事件后, 自动执 行预先执行的收缩日志文件的业务处理脚本。
如图 2所示, 步驟 101 中监控代理端读取监控服务器端的连接信息, 通过该监控服务器端连接信息连接监控服务器端, 包括如下步驟:
步驟 201 , 启动监控代理端,读取监控服务器端连接配置并读取监控代 理端的监控配置;
启动监控代理端具体包括: 启动监控代理程序, 包括地址、 服务端口、 应用地址等服务链接信息。 此外监控项加载器还解析监控代理端的监控配 置文件, 文件中规定了待采集的监控资源类型, 如操作系统、 数据库服务 器等; 监控资源的具体监控项如 Web服务器连接数、 阅读器清点标签速率 等; 以及监控资源采集相关的配置信息, 如数据库服务器地址、 阅读器地 址、 端口等。 资源监控加载器解析监控配置过程中执行必要的检验操作, 如测试监控配置文件中定义的数据库服务器能否访问、 过滤掉无法访问的 配置等。
步驟 202 ,监控代理端向监控服务器端发送连接请求,请求中携带了监 控代理端封装从所述监控配置文件中解析到的待采集的监控项数据。
步驟 203 ,监控服务器端中的预处理模块接收到连接请求,通过持久化 模块查询发起连接请求的监控代理端是否已经注册。 如已经注册, 则执行 步驟 205 , 否则执行步驟 204。
步驟 204,监控服务器解析连接请求中携带的待采集的监控项数据, 构 建代理注册数据, 通过持久化模块记录连接请求中的监控项配置数据。
步驟 205 ,监控服务器使用数据库中该监控代理端的监控数据记录,创 建监控项配置数据, 并返回连接应答。
如图 3所示, 本发明的数据处理流程步驟 102中采用主动数据采集方 式对监控项数据进行采集的具体流程如下:
步驟 301 ,监控代理端中的数据采集器从通信接口获取到监控服务器端 返回的监控资源的监控项配置。
步驟 302,监控项配置中包含主动采集所需的采集周期,数据采集器启 动定时任务以该采集周期定时采集监控项数据。
主动数据采集方式主要用于数据随时间频繁变化这一类型的监控项, 如系统 CPU占用率、 RFID阅读器天线标签清点数量等动态变化的数据。
如图 4所示, 本发明数据处理流程步驟 102中采用被动数据采集方式 对监控项数据进行采集的具体流程如下:
步驟 401,监控代理端中的数据采集器从通信接口获取到监控服务器端 返回的监控资源的监控项配置。
步驟 402,数据采集器根据监控项配置中定义的被动采集所需的配置信 息, 执行监听事件操作, 其中, 所述配置信息包括 Socket监听端口、 监听 事件、 消息主题连接地址。
监控代理端中的数据采集器使用上述类型的配置信息执行监听事件所 需的操作, 如创建 Socket连接、 注册消息服务等。
步驟 403 , 当被动采集的监控项数据源状态发生变化时,通过代理端注 册的方式, 监控服务器端主动通知监控代理端。 监控代理端中的数据采集 器接收到通知后, 构建监控项数据并插入到緩存队列中。
与主动数据采集方式的数据采集不同, 被动数据采集方式主要用于采 集物联网软硬件资源中具有状态类型特点的监控项数据。 所谓的状态类型 监控项数据是指监控项的数值区间只有几种可能, 如状态机一样, 其数值 也只能在这几种状态值中变换, 监控代理端只需监控到这种类型的监控项 数据的状态变化。 而主动数据采集方式周期性获取状态数据是无法有效的 监测到监控资源状态的变化的。 在物联网环境中, RFID阅读器内部通信链 路的可用性、 网络接口的模式等资源的监控项数据具有状态数据的特点, 适合监控系统以被动数据采集方式采集这些资源的监控项数据。 如图 5所示, 步驟 102监控代理端需对数据采集器的监控项数据进行 緩存, 以防止因监控代理端与监控服务器端断链异常导致的重要监控项数 据丟失, 该过程包括如下步驟:
步驟 501 , 计算緩存队列长度, 判断是否已达到预设值的存储上限, 如 还未达到上限值, 则执行步驟 505 , 否则执行步驟 502。
步驟 502 ,读取监控代理端外部持久化配置, 如存在外部持久化配置选 项, 则执行步驟 503 , 否则执行步驟 504。
步驟 503 ,根据持久化配置选项将緩存队列中的监控项数据转存到外部 存储介质, 如数据库表、 文本文件等。
步驟 504,根据緩存队列中监控项数据入队时间,丟弃其中最老的监控 项数据。
步驟 505 , 将待緩存的监控项数据插入到緩存队列中。
如图 6所示, 步驟 104中监控代理端向监控服务器端上报监控项数据, 其中监控代理端緩存队列中的监控项数据处理, 包括如下步驟:
步驟 601 , 监控代理端检查是否存在外部持久化配置。 如存在配置, 则 执行步驟 602, 否则执行步驟 603。
步驟 602, 根据持久化配置选项, 读取存储到外部介质的监控项数据, 删除外部数据记录。
步驟 603 ,使用所述外部读取的及緩存队列中的监控项数据, 构建上报 的监控数据模型、 即预定义类型数据, 使用监控代理端中的通信模块发送 到监控服务器端。
