Yuav ua li cas Network Thawj Coj Saib Xyuas Kev Noj Qab Haus Huv Ntawm Lawv Cov Hauj Lwm
Network xyuas yog ib qho nquag siv IT lub sij hawm. Network saib yog hais txog kev xyaum ua haujlwm ntawm lub computer network siv cov cuab yeej kev tswj tshwj xeeb software. Network saib xyuas systems yog siv los xyuas kom paub meej thiab muaj kev ua tau zoo ntawm cov computers (hosts) thiab cov kev pabcuam hauv network. Lawv cia cov neeg saib xyuas saib xyuas kev siv, kev khiav tsheb, kev qeeb lossis qeeb, hluav taws kub, cov tub ntxhais qhov kev hloov, cov neeg siv khoom nruab nrab thiab kev ua haujlwm ntawm lwm cov ntaub ntawv. Network xyuas systems yog feem ntau ua hauj lwm rau cov neeg loj teev thiab cov tsev kawm ntawv IT networks.
Tseem ceeb nta nyob rau hauv Network Monitoring
Lub kaw lus saib kev sib tham network muaj peev xwm saib xyuas thiab ceeb toom txog kev lag luam lossis kev sib txuas. Nws nquag ntsuas CPU kev siv hom, kev siv qhov sib txuas ntawm network , thiab lwm yam ntawm kev lag luam. Feem ntau nws xa lus-qee zaum hu ua watchdog cov lus-thoob lub network rau txhua tus tswv tsev kom paub tseeb tias nws teb rau cov lus nug. Thaum twg tsis ua tiav, tsis tuaj yeem ua raws li qeeb lossis lwm tus cwj pwm tsis zoo, qhov system no xa xov ntxiv hu ua alerts mus rau lwm qhov chaw xws li tus neeg saib xyuas kev tswj hwm, tus email lossis tus xov tooj qhia rau cov neeg saib xyuas kev khiav dej num.
Network Monitoring Software Tools
Cov ping program yog ib qho piv txwv ntawm cov kev pab cuam saib xyuas network yooj yim. Ping yog ib qho cuab yeej software muaj nyob rau ntawm cov computers feem ntau xa Internet Protocol (IP) xeem lus ntawm ob hom. Txhua tus neeg hauv lub network yuav khiav cov kev ntsuam xyuas ping yooj yim kom paub tseeb tias qhov kev sib txuas ntawm ob lub koos pis tawj ua haujlwm thiab los ntsuas qhov kev sib txuas ua ke tam sim no.
Thaum ping yog ib qho tseem ceeb hauv qee lub sijhawm, qee cov kev sib txuas lus yuav tsum muaj kev soj ntsuam ntau dua hauv tshuab ntawm cov software programs uas tsim los siv los ntawm cov neeg khiav dej num ntawm cov koom txoos loj. Piv txwv ntawm cov pob khoom software yog HP BTO thiab LANDesk.
Ib hom kev saib xyuas network yog tsim los txhawm rau saib xyuas qhov muaj cov web servers. Rau cov lag luam loj loj uas siv lub pas dej ua ke ntawm lub vas sab thoob plaws ntiaj teb, cov txheej txheem no pab ceev nrooj pom cov teeb meem ntawm txhua qhov chaw. Kev saib xyuas lub website muaj nyob rau hauv Internet muaj Monitis.
Yoojyim Network Management Protocol
Yoojyim Network Management Protocol yog ib txoj cai tswj hwm uas muaj xws li kev saib xyuas network software. SNMP yog txoj kev saib xyuas ntau tshaj plaws thiab kev tswj xyuas kev tswj hwm. Nws suav nrog:
- Cov khoom siv nyob rau hauv lub network uas tau raug saib xyuas
- Tus neeg saib xyuas software ntawm cov khoom siv
- Ib qhov kev tswj hwm network (NMS), uas yog ib lub cuab yeej cuab tam uas saib xyuas txhua yam khoom siv ntawm lub network thiab txuas lus qhia txog cov kev pabcuam rau tus thawj xibfwb IT.
Cov thawj coj siv SNMP saib xyuas thiab tswj cov kev sib txuas ntawm lawv tes hauj lwm los ntawm:
- Sau cov lus qhia txog seb qhov bandwidth siv ntau npaum li cas hauv lub network
- Ua kom muaj kev xaiv tsa cov cuab yeej cuab tam mus thov kom muaj kev cai lij choj ntawm cov sijhawm teev tseg
- Qhia rau admin los ntawm cov ntawv xov xwm ntawm kev ntaus tsis ua hauj lwm
- Muab cov ntaub ntawv yuam kev, uas siv tau rau kev txhim kho
- Emailing ib qho kev ceeb toom thaum tus neeg ua hauj lwm ncav cuag ib qho kev teev cia uas tsis muaj qhov chaw qis qis
SNMP v3 yog tam sim no version. Nws yuav tsum raug siv vim nws muaj kev ruaj ntseg nta uas tau ploj lawm hauv versions 1 thiab 2.
