		一般主動(dòng)告警系統(tǒng)的告警信息采集主要有5種方法: 
          ?
          ?1. 在告警服務(wù)器ping各種設(shè)備, 判斷設(shè)備是否存活和掉包率
          ?2. 接收設(shè)備發(fā)過(guò)來(lái)的系統(tǒng)日志(syslog), 并通過(guò)相應(yīng)的規(guī)則庫(kù)(正則表達(dá)式)匹配判斷是否需要告警
          ?3. 接收設(shè)備發(fā)過(guò)來(lái)的snmp Trap信息, 進(jìn)行判斷告警
          ?4. 提取網(wǎng)管系統(tǒng)的告警信息
          ?5. 通過(guò)snmp協(xié)議, 取回相應(yīng)oid的值, 進(jìn)行判斷告警
          ?
          ?什么是snmp:
          ?
          ?Simple Network Management Protocol (SNMP)提供了一些"簡(jiǎn)單"的操作, 允許你更容易的監(jiān)控和管理網(wǎng)絡(luò)設(shè)備, 例如路由器,交換機(jī),服務(wù)器,打印機(jī)等等. 通過(guò)snmp你可以監(jiān)控很多信息, 例如端口流量, 路由器里面的溫度, cpu使用率等等. 學(xué)習(xí)snmp其實(shí)并不是特別簡(jiǎn)單, 請(qǐng)通過(guò)別的資料學(xué)習(xí)更多的方面, 特別是mib,oid之類(lèi)的概念. 
          ?推薦學(xué)習(xí)Essential SNMP, 2nd Edition這本書(shū).
          ?
          ?如何收集數(shù)據(jù):
          ?
          ?如果安裝了NET-SNMP, 可以從http://net-snmp.sourceforge.net/獲取NET-SNMP的RPM包以及源代碼。下載
          解壓后
          su?-
          cd?ucd          -snmp-4.2.3
          .          /configure?--prefix=/usr??<--?缺省是/usr/local
          make?clean?all
          make?install

          snmpget?<target>?public?system.sysDescr.0

          應(yīng)該可以看到一個(gè)關(guān)于系統(tǒng)的簡(jiǎn)短描述，類(lèi)似這樣:
          system.sysDescr.0?=?Sun?SNMP?Agent,?Ultra-60
          上述命令中的public可以理解為SNMP agent的口令，術(shù)語(yǔ)叫做"community string"。
          許多網(wǎng)絡(luò)設(shè)備、操作系統(tǒng)都用"public"做為缺省"community string"，潛在帶來(lái)安全
          問(wèn)題。應(yīng)該修改這個(gè)缺省"community string"。
          上述命令還可以寫(xiě)成:
          snmpget?<target>?public?.1.3.6.1.2.1.1.1.0

          "system.sysDescr.0"只是".1.3.6.1.2.1.1.1.0"的另一種表述方式，最終還是要轉(zhuǎn)
          換成數(shù)字形式的OID(對(duì)象標(biāo)識(shí)符)。
          snmpget返回一個(gè)值, 類(lèi)型可以是數(shù)值或者字符串等, 還有一個(gè)snmpwalk的操作, 大概就是返回一個(gè)數(shù)組的結(jié)果.
          本系統(tǒng)使用java語(yǔ)言實(shí)現(xiàn), 在網(wǎng)上下載了一個(gè)開(kāi)源的snmp實(shí)現(xiàn), 假設(shè)有以下工具類(lèi):

          在上面的main函數(shù), 我們已經(jīng)基本可以實(shí)現(xiàn)snmp的告警功能了, 可是這樣相當(dāng)不靈活, 全部都是硬編碼, 每添加一個(gè)新的snmp告警都要新加代碼模塊
          ?經(jīng)過(guò)分析, 大部分的snmp采集告警都是這樣的過(guò)程:
          ?
          ?1. 取得某設(shè)備的對(duì)象ID(oid)
          ?2. 通過(guò)snmp協(xié)議得到該oid相應(yīng)的值, 賦值給value這個(gè)變量
          ?3. 取當(dāng)前的時(shí)間(秒), 賦值給time這個(gè)變量
          ?4. 取上次采集的值和時(shí)間, 分別賦值給lastValue, lastValue
          ?5. 根據(jù)該oid返回值代表含義, 構(gòu)造一個(gè)表達(dá)式, 這個(gè)表達(dá)式只能包括value, time, lastValue, lastTime這4個(gè)變量,
          ?有時(shí)不必全部用上, 而且該表達(dá)式應(yīng)回一個(gè)布爾類(lèi)型的值, 如果為真則需要告警
          ?6. 保存value, time為lastValue, lastTime, 用來(lái)在下次采集判斷時(shí)使用
          ?
          ?這個(gè)時(shí)候就比較清楚了, 如果有一種動(dòng)態(tài)語(yǔ)言或動(dòng)態(tài)腳本在java環(huán)境里能運(yùn)行就能夠比較靈活的實(shí)現(xiàn)snmp告警了, 不需要硬編碼所有的告警情況, 只需要在ui界面添加修改告警表達(dá)式就ok了
          ?經(jīng)過(guò)在http://www.open-open.com或http://java-source.net上搜索, 發(fā)現(xiàn)BeanShell這個(gè)項(xiàng)目, 官方網(wǎng)站是http://www.beanshell.org/?

          ?Beanshell是用Java寫(xiě)成的，一個(gè)小型的、免費(fèi)的、可以下載的、嵌入式的Java源代碼解釋器，具有對(duì)象腳本語(yǔ)言特性。BeanShell執(zhí)行標(biāo)準(zhǔn)Java語(yǔ)句和表達(dá)式，另外包括一些腳本命令和語(yǔ)法。它將腳本化對(duì)象看作簡(jiǎn)單閉包方法（simple method closure）來(lái)支持，就如同在Perl和JavaScript中的一樣。

          以下是用BeanShell改寫(xiě)的snmp告警模塊:
