K pot\u0159eb\u011b monitorov\u00e1n\u00ed se dost\u00e1v\u00e1me r\u016fzn\u00fdmi cestami. N\u011bkte\u0159\u00ed m\u011bli \u0161t\u011bst\u00ed a monitoring byl zaveden mate\u0159skou spole\u010dnost\u00ed. Tady je to jednoduch\u00e9, u\u017e za v\u00e1s v\u0161echno promysleli \u2014 \u010d\u00edm, co a jak monitorovat. A pravd\u011bpodobn\u011b u\u017e napsali pot\u0159ebn\u00e9 p\u0159\u00edru\u010dky a vysv\u011btlen\u00ed. Jin\u00ed se k t\u00e9to pot\u0159eb\u011b dost\u00e1vaj\u00ed sami a iniciativa obvykle vych\u00e1z\u00ed z IT odd\u011blen\u00ed. Nev\u00fdhodou je, \u017ee v\u0161echny \u0161r\u00e1my a p\u00e1dy si budete muset osvojit na vlastn\u00ed k\u016f\u017ei. Na druhou stranu je i pozitivum \u2014 m\u016f\u017eete si vybrat jak\u00fdkoli monitoringov\u00fd syst\u00e9m a sledovat pouze to, co je nezbytn\u00e9, stejn\u011b jako si vymyslet vlastn\u00ed principy reakce na probl\u00e9my. V r\u016fzn\u00fdch obdob\u00edch jsem pracoval v r\u016fzn\u00fdch firm\u00e1ch, ale tam, kde jsem byl bl\u00edzko monitorov\u00e1n\u00ed, jsem \u0161el tou druhou cestou.

Kr\u00e1tk\u00fd exkurz do minulosti<\/h3>\n

\nPrvn\u00ed \u201ezku\u0161enost\u201c byla v d\u00e1vn\u00e9 minulosti. To byl jeden z m\u00edstn\u00edch poskytovatel\u016f, kde jsem n\u00e1hle byl skladn\u00edkem. \u0158\u00edzen\u00e9 za\u0159\u00edzen\u00ed tehdy bylo drah\u00e9, a proto se kr\u00e1de\u017ee a v\u00fdpadky sledovaly pomoc\u00ed Friendly Pinger, pinguj\u00edc n\u011bkolika klienty, kte\u0159\u00ed byli neust\u00e1le nebo t\u00e9m\u011b\u0159 neust\u00e1le online. Fungovalo to tak n\u011bjak, ale lep\u0161\u00ed nebylo.<\/p>\n

Pak u jin\u00e9ho m\u00edstn\u00edho poskytovatele administr\u00e1to\u0159i pou\u017e\u00edvali Nagios. V podstat\u011b jsem k n\u011bmu nem\u011bl p\u0159\u00edstup, tak\u017ee jsem nemohl posoudit jeho mo\u017enosti. Nicm\u00e9n\u011b, \u0159\u00edzen\u00e9 za\u0159\u00edzen\u00ed se pou\u017e\u00edvalo na ka\u017ed\u00e9m z bod\u016f a pravd\u011bpodobn\u011b monitoring byl efektivn\u00edm n\u00e1strojem.<\/p>\n

Pak jsem se dostal do spole\u010dnosti, kter\u00e1 byla p\u00e1te\u0159n\u00edm poskytovatelem a jako dce\u0159in\u00e1 slu\u017eba nab\u00edzela dom\u00e1c\u00ed internet. Zde se pou\u017e\u00edval Zenoss v cel\u00e9 sv\u00e9 kr\u00e1se. Do hloubky jsem se do n\u011bj nepou\u0161t\u011bl, ale dok\u00e1zal jsem poc\u00edtit jeho moc a u\u017eite\u010dnost \u2014 jen ta magie regexp\u016f, to stoj\u00ed za to\u2026 Syst\u00e9m jsme nastavovali a psali p\u0159edpisy promy\u0161len\u00ed profesion\u00e1lov\u00e9 ve sv\u00e9m oboru.<\/p>\n

A tak na dal\u0161\u00edm m\u00edst\u011b pr\u00e1ce jsem p\u0159i\u0161el k pot\u0159eb\u011b dozv\u011bd\u011bt se o probl\u00e9mech d\u0159\u00edv, ne\u017e o tom n\u011bjak\u00fd \u00fa\u010detn\u00ed za\u017ealuje. Vzhledem k tomu, \u017ee \u010das na kreativn\u00ed experimenty byl, \u0161el jsem se pod\u00edvat, co n\u00e1m nab\u00edz\u00ed lidov\u00e1 v\u00fdroba.<\/p>\n

Mu\u010den\u00ed v\u00fdb\u011bru<\/h3>\n

\nVe skute\u010dnosti se uk\u00e1zalo, \u017ee v\u00fdb\u011br byl ne\u010dekan\u011b jednoduch\u00fd. Samoz\u0159ejm\u011b, na chut\u011b a barvy jsou v\u0161echny fixy r\u016fzn\u00e9, tak\u017ee moje krit\u00e9ria a n\u00e1zory, kter\u00e9 byly aktu\u00e1ln\u00ed v t\u00e9 dob\u011b, nemus\u00ed b\u00fdt pro v\u00e1s vhodn\u00e9. Vzpomn\u011bl jsem si na n\u011bkolik syst\u00e9m\u016f a shrnu sv\u00e9 my\u0161lenky o nich.<\/p>\n

Jako Windows administr\u00e1tor mi jako prvn\u00ed p\u0159i\u0161el na mysl Custer Center v cel\u00e9 sv\u00e9 kr\u00e1se. Prvn\u00edm a hlavn\u00edm plusem je jeho integrace do prost\u0159ed\u00ed Microsoft, a to bez jak\u00e9hokoliv kouzlen\u00ed s bubny, ale nativn\u011b. Druh\u00fdm plusem je komplexn\u00ed p\u0159\u00edstup. Bu\u010fme up\u0159\u00edmn\u00ed, System Center nen\u00ed \u010dist\u011b monitoringov\u00e1 syst\u00e9m \u2014 je to p\u0159ece jen syst\u00e9m pro spr\u00e1vu infrastruktury. To je ale tak\u00e9 prvn\u00ed m\u00ednus. Nasazen\u00ed tohoto monstra pouze pro monitoring ned\u00e1v\u00e1 \u017e\u00e1dn\u00fd smysl. Ale pokud by byly pot\u0159eba r\u016fzn\u00e9 typy z\u00e1loh a nasazen\u00ed milionu VDS... A cena implementace tak\u00e9 radostn\u011b nep\u0159ekvap\u00ed, proto\u017ee se budete muset rozlou\u010dit s pen\u011bzi dvakr\u00e1t \u2014 nejprve za licence a pak za serverech<\/a>, kde to bude \u017e\u00edt.<\/p>\n

D\u00e1le se vr\u00e1t\u00edme do minulosti s Nagios. Syst\u00e9m hned odpadl, proto\u017ee konfigurace syst\u00e9mu rukama prost\u0159ednictv\u00edm konfigura\u010dn\u00edch soubor\u016f \u010din\u00ed syst\u00e9m neudr\u017eovateln\u00fdm. Neodsuzuji lidi, kte\u0159\u00ed maj\u00ed r\u00e1di listovat p\u0159ibli\u017en\u011b patn\u00e1cti sty stejn\u00fdmi \u0159\u00e1dky, aby opravili jedin\u00fd parametr, ale ani j\u00e1 to tak d\u011blat nechci.<\/p>\n

Zenoss. Skv\u011bl\u00fd syst\u00e9m! V\u0161echno je, v\u0161echno zvl\u00e1d\u00e1, nastavuje se za p\u0159ijateln\u00e9 \u00farovn\u011b slo\u017eitosti, ale je t\u011b\u017ekop\u00e1dn\u00fd. Nem\u011bli jsme takov\u00e9 rozsahy, nikdy jsme nepou\u017e\u00edvali \u017e\u00e1dn\u00e9 vno\u0159en\u00e9 skupiny. A samotn\u00fd motor se uk\u00e1zal jako p\u0159\u00edli\u0161 n\u00e1ro\u010dn\u00fd na zdroje. Pro\u010d? Vzdali jsme se.<\/p>\n

Zabbix \u2014 na\u0161e volba. P\u0159il\u00e1kaly n\u00e1s dost n\u00edzk\u00e9 syst\u00e9mov\u00e9 po\u017eadavky a jednoduchost spu\u0161t\u011bn\u00ed. V podstat\u011b to trvalo jen n\u011bkolik minut. St\u00e1hnout obraz pro VMWare a stisknout tla\u010d\u00edtko \u201ezapnout virtu\u00e1lku\u201c. To je v\u0161e! Dokonce v\u00e1m \u0159eknu, pro na\u0161e pot\u0159eby by n\u00e1m zcela sta\u010dil tento \u201estartovn\u00ed obraz\u201c, i kdy\u017e jsme brzy nasadili v\u0161e, jak to m\u00e1 b\u00fdt.<\/p>\n

V p\u016fvodn\u00edm seznamu byl je\u0161t\u011b Cacti, ale k n\u011bmu jsme se prost\u011b nedostali. Jak\u00fd m\u00e1 smysl, kdy\u017e Zabbix vzlet\u011bl na prvn\u00ed pokus a v\u0161em se hned zal\u00edbil? Proto nemohu \u0159\u00edci nic o Cacti.<\/p>\n

Po napsan\u00e9m<\/h3>\n

\nSpole\u010dnost, ve kter\u00e9 jsem implementoval Zabbix, \u00fasp\u011b\u0161n\u011b zkrachovala. Majitel \u0159ekl: \u201eU\u017e m\u011b to v\u0161echno nud\u00ed, zav\u00edr\u00e1m podnik\u201c, tak\u017ee o monitorov\u00e1n\u00ed tam nen\u00ed moc co vypr\u00e1v\u011bt. Sledovali jsme servery<\/a>, internet a tunely na v\u0161ech platform\u00e1ch a sb\u00edrali jsme m\u011b\u0159i\u010de z tisk\u00e1ren.<\/p>\n

Pot\u00e9 v m\u00e9m \u017eivot\u011b kr\u00e1tce byl PRTG. Podle m\u00e9ho n\u00e1zoru skv\u011ble funguje s Windows syst\u00e9my, pou\u017e\u00edv\u00e1 zaj\u00edmav\u00fd mechanismus pr\u00e1ce s agenty a stoj\u00ed nehor\u00e1zn\u00e9 pen\u00edze. To v\u0161e p\u0159itom p\u0159i dost smutn\u00e9 ideologii p\u0159\u00edstupu k aktualizac\u00edm verz\u00ed.<\/p>\n

Spole\u010dnost, ve kter\u00e9 nyn\u00ed pracuji, pou\u017e\u00edv\u00e1 Zabbix. To nebyla m\u00e1 volba, ale jsem s t\u00edm spokojen a zcela to podporuji. Vzhledem k stavu monitorovac\u00edho syst\u00e9mu p\u0159ed m\u00fdm p\u0159\u00edchodem jsem tak\u0159ka v\u0161echno obnovil. Bylo mi jasn\u00e9, \u017ee \u201ed\u011bl\u00e1me n\u011bco \u0161patn\u011b\u201c. A dokonce byla spu\u0161t\u011bna nov\u00e1 server<\/a> instalace se Zabbixem, ale nebyl tam nikdo, kdo by se t\u00e9to \u00fakolu ujal a dovedl ho do konce. Pln\u00e9ho osv\u00edcen\u00ed v monitorov\u00e1n\u00ed jsme je\u0161t\u011b nedos\u00e1hli, ale douf\u00e1m, \u017ee v\u00edme, jak\u00fdm sm\u011brem j\u00edt. Proces dosa\u017een\u00ed dokonalosti v monitorov\u00e1n\u00ed je nekone\u010dn\u00fd, p\u0159esto\u017ee jsem si u\u017e formuloval z\u00e1kladn\u00ed teze.
