Hei alle sammen, Habr-folk!<\/p>\n

Faktisk ble jeg motivert til \u00e5 skrive denne artikkelen av de hyppige utl\u00f8serne i overv\u00e5kningssystemet Zabbix for fall i hastigheten p\u00e5 nettverket til \u00abTele2\u00bb. P\u00e5 avsidesliggende steder, der det er umulig \u00e5 legge fiberoptikk, er det satt opp port forwarding av registratorens port via USB-modemer, modifisert for \u00e5 fungere med alle operat\u00f8rer. Her er et enkelt skjema for tilkobling av utstyret:
\n\"Hva
\nFor \u00e5 nevne det, bruker v\u00e5r organisasjon ogs\u00e5 mobilinternett fra \u00abMegafon\u00bb til de samme behovene, men med det har vi ikke slike problemer. <\/a><\/noindex>Problemet er som f\u00f8lger: fra omtrent kl. 12.00 den 07.08.2019, ble varselet fra Zabbix om null hastighet p\u00e5 web-scenariene p\u00e5 sidene til video registratorene s\u00e5 hyppig at e-posten fra avsenderen, angitt i Zabbix-varselet, begynte \u00e5 bli betraktet som spam og ble ikke levert til mottakeren, det vil si meg. Det er ogs\u00e5 viktig \u00e5 merke seg at den bakgrunnsmessige hastigheten p\u00e5 de problematiske nettverkene generelt er tilfredsstillende, men nedgangene, selv om de er kortvarige, g\u00e5r straks til null. Og hvis registratoren sine kanaler \u00abskriver\u00bb p\u00e5 eksterne lagringsenheter, vil det uunng\u00e5elig oppst\u00e5 problemer med integriteten til opptaket, minst, og kanskje til og med med muligheten for \u00e5 koble til den m\u00e5lte registratoren igjen.<\/p>\n

Ved skrivning av denne artikkelen (19:25 10.08.2019) har forekomsten av hastighetsfall blitt mindre hyppig, men hvis det oppst\u00e5r nedgang, er det registratorene som g\u00e5r gjennom \u00abTele2\u00bb. Det er viktig \u00e5 merke seg at dette gjelder hele Moskva og Moskva-regionen. Selv en \u00f8kning av perioden mellom sjekker til 2 minutter endret knapt situasjonen. \u00c5 g\u00e5 tilbake til standard zabbix_server.conf hjalp absolutt ikke (man vet jo aldri). En samtale til \u00abTele2\u00bb sin kundeservice ga ingen forklaringer p\u00e5 det som skjer, annet enn r\u00e5det om \u00e5 sette modemet i blandet modus (antakelig var det snakk om \u00abLTE+UMTS\u00bb), noe som ikke tidligere var n\u00f8dvendig, og hvis det var n\u00f8dvendig, s\u00e5 ikke p\u00e5 alle objekter med \u00abTele2\u00bb samtidig, og problemet ligger \u00e5penbart dypere enn bare valg av protokoll. Jeg vil selvf\u00f8lgelig kontakte bedriftsavdelingen til \u00abTele2\u00bb p\u00e5 mandag for \u00e5 avklare \u00e5rsaken til denne oppf\u00f8rselen i nettverket, men jeg tviler sterkt p\u00e5 at DE vil v\u00e6re interessert i \u00e5 diskreditere seg selv. S\u00e5 denne teksten fungerer som en advarsel, og stiller samtidig sp\u00f8rsm\u00e5let: \u00abHar noen opplevd noe lignende med mobilinternett fra \u201eTele2\u201c eller Zabbix?<\/p>\n

Slik ser mappen for mottak av Zabbix-varsler ut (og slik har det v\u00e6rt i 4 dager p\u00e5 rad):<\/p>\n

\"Hva
\n
\nZabbix-kartet med videoregistratorene (hvis det ikke er klart fra skjermbildet av e-posten at operat\u00f8ren er \u201eTele2\u201c, s\u00e5 er det \u00e5penbart p\u00e5 kartet):<\/p>\n

\"Hva
\n
\nOg en ekstra bekreftelse for alle de tidligere nevnte fakta er synkronisiteten av nedgangene i Moskva og n\u00e6rliggende forsteder, uansett geografisk plassering. Dette inkluderer ikke helt avsidesliggende punkter som Dolmatovo og Ferma, men se bare hvordan grafene deres ser ut:<\/p>\n

\"Hva
\n
\nHer er tidspunktet for nedlagte forbindelser i Sgongnikki:<\/p>\n

\"Hva
\n
\nHer er omr\u00e5det i Sgongnikki:<\/p>\n

\"Hva
\n
\nOmtrent samtidig skjedde det et fall i Strogino:<\/p>\n

\"Hva
\n
\nPlasseringen av Strogino:<\/p>\n

\"Hva
\n
\nOg til slutt den samme \u201enullen\u201c i Shcherbinka:<\/p>\n

\"Hva
\n
\nDen er her:<\/p>\n

\"Hva
\n
\nEn liten tidsforsinkelse skyldes forskjellen i starten p\u00e5 sjekken for serveren<\/a> Zabbix, men generelt, som vi ser, er nettverksoppf\u00f8rselen p\u00e5 grafene identisk p\u00e5 tidspunktet for denne spesifikke sjekken. Takk for oppmerksomheten, jeg ser frem til \u00e5 h\u00f8re om noen lignende observasjoner fra dere. Ha det bra alle sammen.
