Tere! See artikkel r\u00e4\u00e4gib sellest, kuidas me lasime endale luua uue monitorimiss\u00fcsteemi. See erineb olemasolevatest selle poolest, et see v\u00f5imaldab k\u00f5rge sagedusega s\u00fcnkroonselt m\u00f5\u00f5tmeid k\u00e4tte saada ning tarbib v\u00e4ga v\u00e4he ressursse. K\u00fcsimise sagedus v\u00f5ib ulatuda 0,1 millisekundini ja s\u00fcnkroniseerimise t\u00e4psus m\u00f5\u00f5tmiste vahel on 10 nanosekundit. K\u00f5ik binaarfailid v\u00f5tavad 6 megabaiti. <\/p>\n

Need for such solutions arises in situations where the capacity of a single channel is insufficient. For example, transportation, video surveillance systems, real-time video streaming, broadcasting live television and radio programs, and any remote locations where only representatives of the major telecommunications players are available, resulting in inadequate speeds on a single modem\/channel.
\nFor each of these areas, we produce a separate line of devices, although the software component is nearly identical, with a quality monitoring system being one of its key modules, without which the product would be impossible.<\/p>\n

<\/p>\n

Over the years, we have developed a multi-level, fast, cross-platform, and lightweight monitoring system. This is something we wish to share with the esteemed community.<\/p>\n

<\/p>\n

\u00dclesande seadmine<\/h2>\n

<\/p>\n

The monitoring system provides metrics of two fundamentally different classes: real-time metrics and all others. The system had only the following requirements:<\/p>\n

<\/p>\n

    \n
  1. High-frequency synchronous acquisition of real-time metrics and their transmission to the communication management system without delays.
    \nK\u00f5rge sagedus ja erinevate m\u00f5\u00f5dikute s\u00fcnkroniseerimine ei ole mitte lihtsalt oluline, vaid eluliselt vajalik andmeedastuskanalite entropia anal\u00fc\u00fcsimiseks. Kui \u00fche andmeedastuskanali keskmine viivitus on 30 millisekundit, siis \u00fchekordne \u00fche millisekundi s\u00fcnkroniseerimisviga teiste m\u00f5\u00f5dikute vahel toob kaasa ligikaudu 5% v\u00f5rgu kanali kiiruslanguse. Kui me teeme 1 millisekundi s\u00fcnkroniseerimisvea neljas kanalis, v\u00f5ib kiirus langeva hindamine kergesti langeda kuni 30%. Peale selle muutub entropia kanalites v\u00e4ga kiiresti, seega, kui me m\u00f5\u00f5dame seda harvem kui \u00fcks kord 0,5 millisekundi jooksul, siis kiiretel kanalitel v\u00e4ikese viivitusega saame me t\u00f5sise kiiruslanguse. Loomulikult ei ole selline t\u00e4psus vajalik k\u00f5igi m\u00f5\u00f5dikute ja mitte k\u00f5ikides tingimustes. Kui kanali viivitus on 500 millisekundit, millega me t\u00f5epoolest kokku puutume, siis 1 millisekundi t\u00f5rge ei paista peaaegu silma. Samuti, elut\u00e4htsate s\u00fcsteemide m\u00f5\u00f5dikute jaoks on meil piisav jaotusfrequentse ja s\u00fcnkroniseerimine 2 sekundi jooksul, kuid iseenda j\u00e4lgimisseade peab suutma t\u00f6\u00f6tada \u00e4\u00e4rmiselt k\u00f5rgete m\u00f5\u00f5tmise sageduste ja \u00e4\u00e4rmiselt t\u00e4pse m\u00f5\u00f5dikute s\u00fcnkroniseerimisega.<\/li>\n
  2. Minimaalne ressursikasutus ja \u00fchtne virna.
    \nL\u00f5ppseade v\u00f5ib olla kas v\u00f5imas pardakompleks, mis anal\u00fc\u00fcsib teedeolusid v\u00f5i viib l\u00e4bi bio-meetrilist andmete kogumist, v\u00f5i siis peopesa suurune arvuti, mida kannab eri\u00fcksuse s\u00f5dur, et edastada reaalajas videot halva \u00fchenduse tingimustes. Sellise arhitektuuride ja arvutusv\u00f5imekuse mitmekesisuse juures tahaksime, et meil oleks \u00fchtne tarkvarakuhja.<\/li>\n
  3. Katusarhitektuur
    \nM\u00f5\u00f5dikud peavad olema kogutud ja koondatud l\u00f5ppseadmest, omama kohalikku andmesalvestust ning visualiseerimist reaalajas ja retrospektiivselt. Kui \u00fchendus on olemas, tuleb andmed edastada keskse monitoringu s\u00fcsteemi. Kui \u00fchendust pole, peab edastamise j\u00e4rjekord kogunema ja mitte tarbima operatiivm\u00e4lu. <\/li>\n
  4. API integratsiooniks kliendi monitoringu s\u00fcsteemiga, kuna kellelegi ei ole vaja palju monitoringu s\u00fcsteeme. Klient peab koguma andmeid igasugustelt seadmetelt ja v\u00f5rkudelt \u00fchte monitooringusse.<\/li>\n<\/ol>\n

    Mis v\u00e4lja tuli<\/h2>\n

    <\/p>\n

    Kuna mitte koormata juba niigi mahukat teksti, ei hakka ma tooma n\u00e4iteid ega m\u00f5\u00f5te k\u00f5ikidest j\u00e4lgimiss\u00fcsteemidest. See tooks kaasa veel \u00fche artikli. \u00dctlen lihtsalt, et me ei leidnud \u00fchtegi j\u00e4lgimiss\u00fcsteemi, mis suudaks samal ajal m\u00f5\u00f5ta kahte metoodikat t\u00e4psusega alla \u00fche millisekundi ja t\u00f6\u00f6taks sama t\u00f5husalt nii ARM-architectuuri 64MB RAM-iga kui ka x86_64 architectuuri 32GB RAM-iga. Seet\u00f5ttu otsustasime kirjutada oma s\u00fcsteemi, mis oskab k\u00f5ike seda teha. Siin on, mida me saavutasime:<\/p>\n

    Peamise programmeerimiskeelena nii seadmes kui ka andmekeskuses kasutame Go keelt. Selle mitme\u00fclesandega teostus on oluliselt lihtsustanud elu ja v\u00f5imaldanud iga teenuse jaoks saada \u00fche staatiliselt lingitud k\u00e4ivitatava binaarfaili. Selle tulemuseks on m\u00e4rkimisv\u00e4\u00e4rne ressursi, meetodite ja teenuse paigutamise liikide kokkuhoid, samuti arendamise ja koodi silumisaja kokkuhoid. <\/p>\n

    <\/p>\n

    S\u00fcsteem tugineb klassikalisele modulaarsele p\u00f5him\u00f5ttele ja sisaldab mitmeid alam-s\u00fcsteeme:<\/p>\n

    <\/p>\n

      \n
    1. M\u00f5\u00f5dikute registreerimine.
      \nIga m\u00f5\u00f5dikut teenindab oma voog ning need s\u00fcsynhroniseeritakse kanalite kaudu. Oleme saavutanud s\u00fcsinhroniseerimise t\u00e4psuse kuni 10 nanossekundi.<\/li>\n
    2. M\u00f5\u00f5dikute s\u00e4ilitamine
      \nMe valisime omavahel, kas kirjutada oma ajas\u00fcsteemi andmehoidla v\u00f5i kasutada midagi olemasolevat. Andmebaas on vajalik tagasivaate andmete jaoks, mida hiljem visualiseeritakse. St, selles ei ole andmeid kanalite viivituste kohta iga 0,5 millisekundi v\u00f5i veateadete kohta transpordiv\u00f5rgus, vaid on kiirus igal liidese puhul iga 500 millisekundi j\u00e4rel. Lisaks k\u00f5rgetele n\u00f5udmistele platvormidevahelisele \u00fchilduvusele ja madalale ressursikasutusele, on meie jaoks \u00e4\u00e4rmiselt oluline, et saaksime andmeid t\u00f6\u00f6delda seal, kus nad asuvad. See s\u00e4\u00e4stab tohutult arvutusressursse. Alates 2016. aastast oleme kasutnud Tarantooli andmebaasi k\u00e4esolevas projektis ja ei n\u00e4e hetkel vahetusohtu. Paindlik, optimaalse ressursikanatsemisega, ning enam kui piisava tehnilise toe tagamisega. Samuti on Tarantoolis rakendatud GIS moodul. Kuigi see ei ole nii v\u00f5imas kui PostGIS, piisab sellest meie jaoks, et salvestada teatud asukohta seotud m\u00f5\u00f5dikuid (relevantne transportimiseks). <\/li>\n
    3. M\u00f5\u00f5dikute visualiseerimine
      \nSiin on k\u00f5ik suhteliselt lihtne. V\u00f5tame andmed andmehoidlast ja n\u00e4itame neid kas reaalajas v\u00f5i tagasivaates. <\/li>\n
    4. Andmete s\u00fcnkroniseerimine keskse monitoorimisse s\u00fcsteemiga.

Alam-s\u00fcsteemi salvestus on samuti \u00fcles ehitatud Tarantoolile. See tagab meile m\u00e4rkimisv\u00e4\u00e4rse kiirus ajaveergude kogumisel tuhandest seadmest ning lahendab t\u00e4ielikult andmete s\u00fcnkroonimise nende seadmetega.

      1. InfluxDB kaotab andmeid, kui toide katkeb. \u00dcldiselt p\u00f6\u00f6rdub klient kiiresti tagasi k\u00f5ikide seadmetelt saadud andmete juurde ja andmebaasis pole andmeid, mis oleks vanemad kui 5 minutit, kuid tulevikus v\u00f5ib see muutuda probleemiks.<\/li>\n
      2. Grafana'il on mitmeid probleem, mis on seotud andmete agregatsiooni ja s\u00fcnkroonimisega nende kuvamisel. K\u00f5ige levinum probleem on see, kui andmebaasis on ajare\u017eiim kahe sekundi intervalliga, alustades \u00fctleme kell 00:00:00, ja Grafana hakkab n\u00e4itama andmeid agregaadina +1 sekundi pealt.
