Moni, Habr! Kumayambiriro kwa Julayi, Solarwinds adalengeza kutulutsidwa mtundu watsopano wa nsanja ya Orion Solarwinds — 2020.2. Chimodzi mwazinthu zatsopano zomwe zili mu Network Traffic Analyzer (NTA) ndikuthandizira kuzindikira kuchuluka kwa magalimoto a IPFIX kuchokera ku VMware VDS.

Kusanthula kuchuluka kwa magalimoto m'malo osinthika ndikofunikira kuti mumvetsetse kugawa kwa katundu pamakina okhazikika. Mwa kusanthula kuchuluka kwa magalimoto, mutha kuzindikiranso kusamuka kwa makina enieni. M'nkhaniyi tikambirana za IPFIX zoikamo kunja kwa mbali ya VMware kusintha kwenikweni ndi mphamvu za Solarwinds ntchito nayo. Ndipo kumapeto kwa nkhaniyi padzakhala ulalo wa demo yapaintaneti ya Solarwinds (kupeza popanda kulembetsa ndipo ichi sichifanizo). Tsatanetsatane pansi pa odulidwa.

Kuti muzindikire molondola kuchuluka kwa magalimoto kuchokera ku VDS, choyamba muyenera kukonza zolumikizira kudzera pa mawonekedwe a vCenter, kenako ndikusanthula kuchuluka kwa magalimoto ndikuwonetsa malo omwe alandilidwa kuchokera ku hypervisors. Mwachidziwitso, kusinthaku kungathe kukonzedwa kuti mulandire zolemba zonse za IPFIX kuchokera ku adiresi imodzi ya IP yomangidwa ku VDS, koma nthawi zambiri zimakhala zodziwitsa zambiri kuti muwone deta yotengedwa kuchokera kumayendedwe omwe amalandiridwa kuchokera ku hypervisor iliyonse. Magalimoto omwe amabwera adzayimira kulumikizana kuchokera kapena kupita ku makina enieni omwe ali pa hypervisors.

Njira ina yosinthira yomwe ilipo ndikutumiza mitsinje yamkati yokha ya data. Kusankhaku sikuphatikiza zotuluka zomwe zimasinthidwa pakusintha kwakunja ndikuletsa mbiri yamagalimoto obwereza kuti alumikizane ndi VDS. Koma ndizothandiza kwambiri kuletsa njirayi ndikuwunika mitsinje yonse yomwe ikuwoneka mu VDS.

Kukonza magalimoto kuchokera ku VDS

Tiyeni tiyambe ndikuwonjezera chitsanzo cha vCenter ku Solarwinds. Kenako NTA idzakhala ndi chidziwitso chokhudza kasinthidwe ka nsanja.

Pitani ku menyu ya "Manage Node", kenako "Zikhazikiko" ndikusankha "Add Node". Pambuyo pake, muyenera kulowa adilesi ya IP kapena FQDN yachitsanzo cha vCenter ndikusankha "VMware, Hyper-V, kapena Nutanix entities" ngati njira yovotera.

Pitani ku Add Host dialog, onjezani mbiri ya vCenter ndikuyesa kuti mumalize kuyika.

Chitsanzo cha vCenter chidzachita kafukufuku woyambira kwakanthawi, nthawi zambiri mphindi 10-20. Muyenera kuyembekezera kumalizidwa, ndiyeno pokhapo mulole IPFIX kutumiza ku VDS.

Pambuyo pokhazikitsa vCenter kuyang'anira ndikupeza deta yosungira pa kasinthidwe ka pulatifomu, tidzathandiza kutumiza ma CD a IPFIX pa switch. Njira yachangu kwambiri yochitira izi ndi kudzera pa kasitomala wa vSphere. Tiyeni tipite ku tabu ya "Networking", sankhani VDS ndipo pa "Sinthani" tabu tipeza zokonda za NetFlow. VMware imagwiritsa ntchito mawu oti "NetFlow" kutanthauza kutumiza kunja, koma ndondomeko yeniyeni yomwe imagwiritsidwa ntchito ndi IPFIX.

Kuti mutsegule kutumiza kunja, sankhani "Zokonda" kuchokera pamenyu ya "Zochita" pamwamba ndikupita ku "Sinthani NetFlow".

M'bokosi ili la zokambirana, lowetsani adilesi ya IP ya osonkhanitsa yomwe ilinso chitsanzo cha Orion. Mwachikhazikitso, port 2055 imagwiritsidwa ntchito nthawi zambiri. Tikukulimbikitsani kusiya gawo la "Sinthani IP Address" lopanda kanthu, zomwe zidzapangitse kuti ma rekodi oyenda alandilidwe makamaka kuchokera kwa hypervisors. Izi zipereka kusinthika kwa kusefa kwina kwa mtsinje wa data kuchokera ku hypervisors.

Siyani gawo la "Process internal flows" loyimitsidwa, lomwe lidzakuthandizani kuti muwone mauthenga onse: mkati ndi kunja.

Mukatsegula kutumiza kwa mtsinje kwa VDS, mudzafunikanso kuyatsa magulu omwe amagawidwa omwe mukufuna kulandira deta. Njira yosavuta yochitira izi ndikudina kumanja pa VDS navigation bar ndikusankha "Distributed Port Group" kenako "Manage Distributed Port Groups".

Bokosi la zokambirana lidzatsegulidwa momwe muyenera kuyang'ana bokosi la "Monitoring" ndikudina "Kenako".

Mu sitepe yotsatira, mukhoza kusankha enieni kapena magulu onse doko.

Mu sitepe yotsatira, sinthani NetFlow kukhala "Enabled".

Pamene kutumiza kwa mtsinje kumayatsidwa pa VDS ndi magulu ogawidwa, mudzawona zolembera za hypervisors zikuyamba kuyenda mu chitsanzo cha NTA.

Ma Hypervisors amatha kuwoneka pamndandanda wazomwe zimatuluka pamasamba a Manage Flow Sources mu NTA. Sinthani ku "Nodes".

Mutha kuwona zotsatira zokhazikitsira pa demo stand. Samalani ndi kuthekera kogwera pamlingo wa node, mulingo wa protocol yolumikizirana, ndi zina.

Kuphatikizika ndi ma module ena a Solarwinds mu mawonekedwe amodzi kumakupatsani mwayi wofufuza m'magawo osiyanasiyana: onani omwe adalowa mu makina enieni, magwiridwe antchito a seva. (onani chiwonetsero), ndi ntchito pa izo, onani zipangizo zogwirizana maukonde ndi zina zambiri. Mwachitsanzo, ngati netiweki yanu imagwiritsa ntchito protocol ya NBAR2, Solarwinds NTA imatha kuzindikira kuchuluka kwa magalimoto kuchokera Sinthani, magulu kapena Webex.

Cholinga chachikulu cha nkhaniyi ndikuwonetsa kumasuka kwa kukhazikitsa kuwunika ku Solarwinds komanso kukwanira kwazomwe zasonkhanitsidwa. Ku Solarwinds muli ndi mwayi wowona chithunzi chonse cha zomwe zikuchitika. Ngati mukufuna kufotokozera yankho kapena kudzifufuza nokha, siyani pempho mawonekedwe a ndemanga kapena kuitana.

Pa Habré tilinso ndi nkhani njira zaulere za Solarwinds.
