W\u0142a\u015bciwie to pisanie tego artyku\u0142u zosta\u0142o wywo\u0142ane przez cz\u0119sto dzia\u0142aj\u0105ce triggery systemu monitorowania Zabbix dotycz\u0105ce spadku pr\u0119dko\u015bci w sieci \u201eTele2\u201d. W obiektach zdalnych, do kt\u00f3rych nie mo\u017cna podci\u0105gn\u0105\u0107 \u015bwiat\u0142owodu, zorganizowano przekierowanie port\u00f3w rejestratora przez modemy USB, przerobione pod r\u00f3\u017cnych operator\u00f3w. Oto prosty schemat po\u0142\u0105czenia sprz\u0119tu:
\n\"Co
\nA swoj\u0105 drog\u0105, nasza organizacja korzysta r\u00f3wnie\u017c w tych samych potrzebach z mobilnego internetu \u201eMTS\u201d, ale z nim podobnych problem\u00f3w si\u0119 nie obserwuje. <\/a><\/noindex>A problem jest nast\u0119puj\u0105cy: od oko\u0142o po\u0142udnia 07.08.2019, powiadomienia Zabbix o zerowej pr\u0119dko\u015bci wykonywania skrypt\u00f3w webowych na stronach rejestrator\u00f3w wideo sta\u0142y si\u0119 tak cz\u0119ste, \u017ce poczta nadawcy podana w powiadomieniu Zabbix zacz\u0119\u0142a traktowa\u0107 listy trigger\u00f3w jako spam i nie dostarcza\u0107 ich odbiorcy, czyli mi. Wa\u017cne jest te\u017c, \u017ce t\u0142o pr\u0119dko\u015bci problematycznych sieci w og\u00f3le jest zadowalaj\u0105ce, a spadki, cho\u0107 kr\u00f3tkotrwa\u0142e, s\u0105 od razu do zera. A je\u015bli kana\u0142y rejestrator\u00f3w \u201ezapisuj\u0105 si\u0119\u201d na zdalne no\u015bniki, to nieuchronnie pojawi\u0105 si\u0119 problemy z integralno\u015bci\u0105 nagrania co najmniej, a mo\u017ce nawet ca\u0142kowity brak mo\u017cliwo\u015bci ponownego po\u0142\u0105czenia z docelowym rejestratorem.<\/p>\n

W momencie pisania artyku\u0142u (19:25 10.08.2019) cz\u0119stotliwo\u015b\u0107 spadk\u00f3w pr\u0119dko\u015bci zacz\u0119\u0142a si\u0119 zmniejsza\u0107, jednak je\u015bli spadki si\u0119 zdarzaj\u0105, to dotycz\u0105 one w\u0142a\u015bnie rejestrator\u00f3w obs\u0142ugiwanych przez \u201eTele2\u201d. Wa\u017cne jest, aby zaznaczy\u0107, \u017ce mowa jest o ca\u0142ej Moskwie i obwodzie moskiewskim. Nawet wyd\u0142u\u017cenie okresu mi\u0119dzy kontrolami do 2 minut praktycznie nie zmieni\u0142o sytuacji. Powr\u00f3t do domy\u015blnego zabbix_server.conf r\u00f3wnie\u017c nie pom\u00f3g\u0142 (c\u00f3\u017c, r\u00f3\u017cnie bywa). Telefon na infolini\u0119 \u201eTele2\u201d nie przyni\u00f3s\u0142 \u017cadnych wyja\u015bnie\u0144 sytuacji, poza rad\u0105, aby spr\u00f3bowa\u0107 ustawi\u0107 w parametrach modemu tryb mieszany (zapewne chodzi\u0142o o \u201eLTE+UMTS\u201d), co wcze\u015bniej nie by\u0142o wymagane, a je\u015bli ju\u017c, to nie na wszystkich obiektach z operatorem \u201eTele2\u201d jednocze\u015bnie, i problem wyra\u017anie jest g\u0142\u0119bszy ni\u017c wyb\u00f3r protoko\u0142u. Oczywi\u015bcie w poniedzia\u0142ek skontaktuj\u0119 si\u0119 z dzia\u0142em korporacyjnym \u201eTele2\u201d w celu wyja\u015bnienia natury takiego zachowania sieci, ale mocno w\u0105tpi\u0119, \u017ceby tam chcieli si\u0119 jako\u015b zdyskredytowa\u0107. Dlatego ten tekst ma s\u0142u\u017cy\u0107 jako ostrze\u017cenie oraz zapytanie: \u201eczy kto\u015b zauwa\u017cy\u0142 podobne problemy w swoim internecie mobilnym \u201eTele2\u201d lub Zabbix?<\/p>\n

Tak w\u0142a\u015bnie wygl\u0105da z@pierdzielona sytuacja w folderze przyjmuj\u0105cym powiadomienia Zabbix (i tak od 4 dni):<\/p>\n

\nA wisienk\u0105 na torcie dla wszystkich wcze\u015bniej przytoczonych fakt\u00f3w jest synchronizacja spadk\u00f3w w Moskwie i najbli\u017cszej okolicy, niezale\u017cnie od ich geograficznej lokalizacji. Nie uj\u0119to tu bardzo dalekich punkt\u00f3w, takich jak Dalmatiowo i Ferma, chocia\u017c wystarczy spojrze\u0107, jak nieprzyjemnie wygl\u0105daj\u0105 ich wykresy:<\/p>\n
