\nOma t\u00f6\u00f6s tunnen sageli muret infrastruktuuri teabe puudumise \u00fcle ja kui serverite arv suureneb, muutub see t\u00f5eliseks piinamiseks. I even when I administered in small organizations, I always wanted to know where everything was placed, where it was plugged in, who was responsible for which hardware or service, and most importantly \u2014 to keep track of all these changes. When you arrive at a new place and encounter some incident, a lot of time is spent just searching for this information. Next, I will share what I've encountered at RuVDS and how I resolved the issue mentioned in the title.
\n<\/a><\/noindex><\/p>\n

Eelalugu<\/h2>\n

\nOlles ettev\u00f5tte administraator, oli mul v\u00e4he kogemusi andmekeskustes, kuid nurga pealt n\u00e4gin RackTables'i. Seal oli selgelt esitatud rack koos k\u00f5igi serverite, UPS'ide, l\u00fclititega ja k\u00f5ikide \u00fchendustega nende vahel. RuVDS-is ei olnud sarnast s\u00fcsteemi, vaid ainult Exceli\/paberifailid serverite, nende osade, rack-numbrite ja muu sarnase teabega. Sellise l\u00e4henemisega on v\u00e4ga raske j\u00e4lgida muudatusi ja v\u00e4iksemaid komponente. L\u00f5ppude l\u00f5puks on serverite k\u00f5ige olulisem ja sageli vahetatav tarvik \u2014 kettad. On \u00e4\u00e4rmiselt oluline hoida ajakohast teavet kettaste seisundi ja strateegilise varu kohta. Kui ketas kaob RAID-massiivis ja sellele ei ole kiiret asendust, v\u00f5ib see l\u00f5puks p\u00f5hjustada t\u00f5siseid tagaj\u00e4rgi. Seet\u00f5ttu on meil v\u00e4ga vajalik s\u00fcsteem, mis j\u00e4lgib kettaste asukohta ja seisundit, et m\u00f5ista, millest v\u00f5ib puudust tunda ja milliseid konkreetseid mudeleid on vaja osta.<\/p>\n

GLPI, avatud l\u00e4htekoodiga toode, on loodud IT-osakondade t\u00f6\u00f6 parandamiseks ja ITILi ideaalide saavutamiseks. See sisaldab varase inventeerimist ja teenuse juhtimist, samuti teadmusbaasi, teenusekeskust, dokumentide haldust ja palju muud. GLPI-l on palju pluginaid, sealhulgas FusionInventory ja OCS Inventory, mis v\u00f5imaldavad automaatselt koguda teavet arvutite ja muude seadmete kohta agentide ja SNMP kaudu. T\u00e4iendavaid juhiseid GLPI ja pluginade installimiseks leiate teistest artiklitest, parim on \u2014 ametlikus dokumentatsioonis<\/a><\/noindex>. Saate selle meie hostimises installida valmis \u0161abloonile LAMP<\/a><\/noindex>.<\/p>\n

Kuid p\u00e4rast agendi juurutamist avame GLPI-s arvuti komponendid ja n\u00e4eme j\u00e4rgmist:<\/p>\n

\"LSI
\nProbleem on selles, et \u00fckski pluginitest ei saa n\u00e4ha f\u00fc\u00fcsiliste ketaste teavet LSI RAID-massiivides. N\u00e4gin, kuidas see probleem on lahendatud Zabbixis PowerShelli skripti abil lsi-raid.ps1<\/a><\/noindex> otsustasin kirjutada analoogse skripti info edastamiseks GLPI-sse.
\nAndmete diskide kohta RAID-massiivis saab hankida tootja t\u00f6\u00f6riistade abil, LSI puhul on see StorCLI. Sealt saab andmed JSON-formaadis, mida saab t\u00f6\u00f6tlema panna ja edastada GLPI API-le. Diskid seotakse arvutitega, mille on juba loonud FusionInventory. Uuesti skripti k\u00e4ivitamisel v\u00e4rskendab see andmeid diskide kohta ja lisab uusi. Skript Send-RAIDtoGLPI.ps1 asub siin GitHubis<\/a><\/noindex>. J\u00e4rgmisena selgitan, kuidas seda kasutada.<\/p>\n

Mida on vaja<\/h2>\n

<\/p>\n

    \n
  1. GLPI<\/a><\/noindex> versioon 9.5.1 (sellel testiti)<\/li>\n
  2. Plugin FusionInventory<\/a><\/noindex> ja agent Windowsi all<\/li>\n
  3. Windows 2012 R2 (ja uuem) k\u00fclaliss\u00fcsteemina v\u00f5i management-VM, millesse on \u00fchendatud kontroller, PowerShell versioon 4 v\u00f5i uuem<\/li>\n
  4. Paigaldatud MegaRAID draiver<\/li>\n
  5. PowerShelli moodul \u2014 PSGLPI <\/a><\/noindex><\/li>\n
  6. GLPI-s konto Admin profiiliga API kaudu autentimiseks, genereeritud UserToken ja AppToken<\/li>\n<\/ol>\n

    \nOluline t\u00e4helepanek. GLPI-s on mingil p\u00f5hjusel kaks erinevat \u00fcksust ketta mudeli jaoks, kuid ei ole omadust \u201eandmekandja t\u00fc\u00fcp\u201d. Seet\u00f5ttu otsustasin HDD ja SSD omaduse salvestamiseks kasutada rippmen\u00fc\u00fcd \u201eKetasemud\u201d (front\/devicemodel.php?itemtype=DeviceHardDriveModel). Skripti toimimiseks on vajalik, et GLPI andmebaasis oleks need v\u00e4\u00e4rtused, vastasel juhul ei saa see ketasmudelist andmeid salvestada. Seet\u00f5ttu tuleb k\u00f5igepealt lisada see t\u00fchi loend HDD ja seej\u00e4rel SSD, et nende elementide ID-d andmebaasis oleksid 1 ja 2. Kui tuleb teisi, siis asendage selle skripti Read-RAIDtoGLPI.ps1 p\u00e4rast HDD ja SSD kohaliku ID-iga: 1 ja 2. <\/p>\n

    deviceharddrivemodels_id = switch ($MediaType) { "HDD" { "1" }; "SSD" { "2" }; default { "" } }<\/code><\/pre>\n
    \nKui te ei soovi sellega vaeva n\u00e4ha v\u00f5i kui kasutate seda rippmen\u00fc\u00fcd muul viisil, saate selle rea skriptist lihtsalt eemaldada. <\/p>\n
    Samuti tuleb lisada ketaste olekud \u201eElemendi olekud\u201d (\/front\/state.php). Olen lisanud olekud \u201eMediaError\u201d (kui esines v\u00e4hemalt \u00fcks ketta juurde p\u00e4\u00e4semise viga) ja \u201eOK\u201d, rida skripti, kus nende ID-d edastatakse, \u201e2\u201d \u201eOK\u201d jaoks ja \u201e1\u201d \u201eMediaError\u201d jaoks:<\/p>\n
    states_id = switch ($MediaError) { 0 { "2" }; { $_ -gt 0 } { "1" } }<\/code><\/pre>\n
    \nNeedless statuses are for convenience; if you don't need these properties, you can remove this line entirely.<\/p>\n
    Don't forget to specify your variables in the script. $GlpiCreds must contain the URL to the GLPI API server, UserToken, and AppToken.<\/p>\n
    What\u2019s in the script<\/h2>\n
    \nDue to bulky JSON parsing and a multitude of if statements, the script is hard to read, so I will describe its logic here.<\/p>\n
    During the first run on the host, the script scans all controllers and searches for disks in the GLPI database by serial numbers; if it doesn't find any, it searches for the model. If it doesn't find the model either, it adds the new disk model to GLPI and records this disk in the database.<\/p>\n
    With each new pass, the script will attempt to detect new disks, but it cannot remove those that are missing, so this will have to be done manually.<\/p>\n
    Deployment example<\/h2>\n
    \nIn the script repository, there is a script Deploy-Send-RAIDtoGLPI.ps1, which will download a ZIP archive with the necessary files from our GLPI server and deploy them on each host.<\/p>\n
    Failide kopeerimise j\u00e4rel installib skript FusionInventory agendi, mis k\u00e4ivitub igap\u00e4evase \u00fclesandena, ning loob sellele \u00fclesande ka meie skripti jaoks. P\u00e4rast eduka juurutamise l\u00f5petamist n\u00e4eme l\u00f5puks kompuutri \u00abKomponendid\u00bb osas kettaid GLPI-s.<\/p>\n
    Tulemus<\/h2>\n
    \nN\u00fc\u00fcd, kui sisse logime GLPI-sse men\u00fc\u00fcs \u00abSeaded\u00bb -> \u00abKomponendid\u00bb -> \u00abKetas\u00bb, saame kl\u00f5psata ketaste mudelitel ja vaadata nende arvu, et m\u00f5ista, mida meil on vaja osta.<\/p>\n
