使用開放源軟體實作網管系統

本論文將於開放源軟體-Opennms上實作雲端服務的網管系統。本系統主要可分為三個部分：網路管理者、網管系統伺服器、被監控之設備。網路管理者部分可被動的接收由網管系統主機所發送之訊息，例如：警告電子信件以及警告簡訊等。也可主動透過Web Console修改網管系統之設定，或是觀看儲存於網管系統主機的資料，例如：被監控之設備的硬體資訊、雲端服務的線上流量等。網管系統透過輪詢動作依序向被監控之設備索取已定義之資料，並且將資料儲存於網管系統伺服器內部。網管系統可透過事件設定判斷所得到的資料異常與否，並決定是否需要發送警告訊息至使用者端。本論文於此部分增加警告簡訊的傳送機制，並利用網管系統內部資料達到客製化Excel報表的功能。被監控之雲端服務及設備主要為雲端伺服器或是網路路由器等設備。將其網路位址登錄至網管系統後，即可透過網管系統監控該服務的流量資訊；或是判斷該服務以及設備是否正常運作。也可透過在設備上安裝SNMP代理者(Agent)後，更進一步的取得相關資料。本論文於此部分增加個人化代理者，以便網管系統可透過SNMP協定取得所需的特定資料。本論文在開放源軟體-Opennms上新增三大功能：SMS警示機制、Excel Report、Private SNMP Agent。使整體網管系統更加的完備以及貼合商業需求。

In this thesis, we base on open source software-Opennms to implement the network management system (NMS) for cloud services. This system can be divided into three parts: user, network management system server, and monitored equipment. The user part can passively receive warning message that sent by the network management system server when the monitored equipment happen an abnormal event. The user can also configure the network management systems through the Web Console proactively, or view the information stored in the server of the network management system, such as hardware information of the monitored equipment, online traffic. NMS requests the defined data from the monitored equipment through the polling action, and stores the data in the management system server. In this thesis, we propose the warning SMS delivery mechanism to inform the user when the managed system happen an abnormal event. In the meanwhile, we apply the information within the network management system to achieve the functionality report by Excel. The server can be installed the SNMP agent to further get relevant information. In this part, we construct the private MIB in SNMP agent, so that the server of NMS can obtain specific information through the SNMP protocol. The contribution of this thesis is to implement three new main functions in Opennms: SMS Alarm Mechanism, Excel Report, and Private SNMP agent. With the new functions, overall network management system can be more complete and fit the business needs.
