Hej alla, habrovchane!<\/p>\n

Egentligen blev jag inspirerad att skriva den h\u00e4r artikeln av de ofta utl\u00f6sande triggarna fr\u00e5n \u00f6vervakningssystemet Zabbix f\u00f6r nedg\u00e5ng i hastighet i n\u00e4tverket 'Tele2'. P\u00e5 avl\u00e4gsna objekt d\u00e4r det inte \u00e4r m\u00f6jligt att dra fiberoptik har portforwarding organiserats genom USB-modem som \u00e4r omprogrammerade f\u00f6r olika operat\u00f6rer. H\u00e4r \u00e4r ett enkelt sambandsschema f\u00f6r utrustningen:
\n\"Vad
\nF\u00f6r \u00f6vrigt anv\u00e4nder v\u00e5r organisation ocks\u00e5 mobilinternet fr\u00e5n 'MegaFon' f\u00f6r samma \u00e4ndam\u00e5l, men med det har vi inte upplevt n\u00e5gra liknande problem. <\/a><\/noindex>Problemet \u00e4r f\u00f6ljande: fr\u00e5n och med ungef\u00e4r klockan 12 den 07.08.2019 har Zabbix-varslen om noll hastighet n\u00e4r det g\u00e4ller webbskript p\u00e5 videos\u00e4kerhetskamerornas sidor blivit s\u00e5 frekventa att avs\u00e4ndarens e-postadress som anges i Zabbix-varslet b\u00f6rjade uppfatta triggarna som skr\u00e4ppost och inte leverera dem till mottagaren, det vill s\u00e4ga mig. Det \u00e4r ocks\u00e5 v\u00e4rt att n\u00e4mna att den bakgrundshastighet f\u00f6r de problematiska n\u00e4tverken \u00f6verlag \u00e4r tillfredsst\u00e4llande, \u00e4ven om fallen \u00e4r kortvariga, de g\u00e5r alltid ner till noll. Och om registratorernas kanaler 'skriver' till avl\u00e4gsna lagringsmedium, kommer det ofr\u00e5nkomligen att uppst\u00e5 problem med integriteten i inspelningen \u00e5tminstone, eller till och med med om\u00f6jligheten att \u00e5teransluta till den avsedda registratorn.<\/p>\n

Vid skrivandet av denna artikel (19:25 10.08.2019) blev frekvensen av hastighetsfall mindre frekvent, men om ett fall intr\u00e4ffar, handlar det just om registratorerna som \u00e4r kopplade via \"Tele2\". Det \u00e4r mycket viktigt att notera att detta handlar om hela Moskva och Moskva-regionen. \u00c4ven en \u00f6kning av perioden mellan kontrollerna till 2 minuter f\u00f6r\u00e4ndrade situationen knappt. \u00c5terst\u00e4llning av den standardinst\u00e4llningen zabbix_server.conf hj\u00e4lpte heller inte (man vet ju aldrig). Ett samtal till \"Tele2\"s support gav inga f\u00f6rklaringar till vad som p\u00e5gick, f\u00f6rutom r\u00e5det att f\u00f6rs\u00f6ka st\u00e4lla in en blandad l\u00e4ge i modeminst\u00e4llningarna (troligen syftande p\u00e5 \"LTE+UMTS\"), vilket tidigare inte kr\u00e4vdes, och om det kr\u00e4vdes, inte p\u00e5 alla objekt med operat\u00f6ren \"Tele2\" samtidigt, och problemet verkar uppenbarligen ligga djupare \u00e4n val av protokoll. Jag kommer sj\u00e4lvklart att kontakta f\u00f6retagsavdelningen p\u00e5 \"Tele2\" p\u00e5 m\u00e5ndag f\u00f6r att klarl\u00e4gga orsaken till detta n\u00e4tverksbeteende, men jag tvivlar starkt p\u00e5 att de d\u00e4r vill discreditera sig sj\u00e4lva. D\u00e4rf\u00f6r fungerar detta inl\u00e4gg som en varning och fr\u00e5gar dessutom: \"Har n\u00e5gon annan m\u00e4rkt n\u00e5got liknande i sin mobilinternet fr\u00e5n 'Tele2' eller Zabbix?<\/p>\n

S\u00e5 h\u00e4r ser mappen f\u00f6r att ta emot Zabbix-notifikationer ut (och det har sett ut s\u00e5 h\u00e4r i 4 dagar i rad):<\/p>\n

\"Vad

\"Vad
\n
\nOch gr\u00e4dden p\u00e5 moset f\u00f6r alla tidigare n\u00e4mnda fakta \u00e4r synkroniseringen av fallen i Moskva och n\u00e4rliggande f\u00f6rorter, oavsett deras geografi. H\u00e4r har vi inte inkluderat helt avl\u00e4gsna punkter som Dolmatovo och Ferma, men titta bara p\u00e5 hur skarpa deras diagram ser ut:<\/p>\n

\nEn liten tidsm\u00e4ssig desynkronisering beror p\u00e5 skillnaden i b\u00f6rjan av kontrollen p\u00e5 servern<\/a> Zabbix, men \u00f6verlag ser vi, som vi kan se, att n\u00e4tverksbeteendet p\u00e5 diagrammen \u00e4r identiskt f\u00f6r tiden f\u00f6r just denna kontroll. Tack f\u00f6r att ni lyssnade, jag ser fram emot att h\u00f6ra om n\u00e5gra liknande observationer kring detta. Hej d\u00e5 allihopa.
