Administratorii de sistem se \u00eempart \u00een dou\u0103 categorii \u2014 cei care deja folosesc monitorizarea \u0219i cei care \u00eenc\u0103 nu o fac.
\nO glum\u0103 de umor<\/i>.<\/i><\/p>\n

Necesitatea monitoriz\u0103rii vine pe c\u0103i diferite. Unii au noroc \u0219i monitorizarea a venit de la compania mam\u0103. Aici totul e simplu, s-a g\u00e2ndit deja la toate \u2014 ce, cum \u0219i c\u00e2nd s\u0103 monitorizezi. Chiar sunt siguri c\u0103 au scris deja manualele \u0219i explica\u021biile necesare. Al\u021bii ajung la aceast\u0103 necesitate pe cont propriu, ini\u021biativa provenind, de obicei, din departamentul IT. Dezavantajul este c\u0103 va trebui s\u0103 \u00eenve\u021be pe propria piele toate gre\u0219elile \u0219i obstacolele. Exist\u0103 \u0219i avantaje \u2014 po\u021bi s\u0103 alegi orice sistem de monitorizare \u0219i s\u0103 monitorizezi doar ceea ce este necesar, de asemenea, po\u021bi s\u0103 \u00ee\u021bi creezi propriile principii de reac\u021bie la probleme. De-a lungul timpului, am lucrat \u00een diverse companii, \u00eens\u0103 acolo unde am fost aproape de monitorizare, am urmat a doua cale.
\n<\/a><\/noindex><\/p>\n

O scurt\u0103 incursiune \u00een trecut<\/h3>\n

\nPrima \"experien\u021b\u0103\" a fost cu mult timp \u00een urm\u0103. A fost unul dintre furnizorii locali, unde am fost, dintr-o dat\u0103, magaziner. Echipamentele gestionate erau scumpe pe atunci, a\u0219a c\u0103 furturile \u0219i \u00eentreruperile erau monitorizate folosind Friendly Pinger, ping\u00e2nd c\u00e2\u021biva clien\u021bi care erau conecta\u021bi constant sau aproape constant. Func\u021biona cum putea, dar nu era mai bine.<\/p>\n

Apoi, la un alt furnizor local, administratorii foloseau Nagios. Din punct de vedere teoretic, nu aveam acces acolo, a\u0219a c\u0103 nu puteam evalua capacit\u0103\u021bile sale. Cu toate acestea, echipamentele gestionate erau folosite \u00een fiecare loca\u021bie \u0219i, probabil, monitorizarea era un instrument eficient.<\/p>\n

Apoi am ajuns \u00eentr-o companie care este un furnizor de backbone \u0219i oferea internet de acas\u0103 ca serviciu secundar. Aici se folosea Zenoss \u00een toat\u0103 splendoarea sa. Nu am aprofundat foarte mult, dar am reu\u0219it s\u0103 simt toat\u0103 puterea \u0219i beneficiile sale \u2014 doar magia regex-urilor ce merit\u0103\u2026 Am str\u00e2ns, configurat sistemul \u0219i scris regulamente profesioni\u0219ti g\u00e2nditori.<\/p>\n

\u0218i astfel, la urm\u0103toarea mea slujb\u0103, am ajuns la necesitatea de a afla despre probleme \u00eenainte ca vreun contabil s\u0103 se pl\u00e2ng\u0103. Av\u00e2nd \u00een vedere c\u0103 timpul pentru experimente creative era limitat, m-am dus s\u0103 v\u0103d ce ne ofer\u0103 industria popular\u0103.<\/p>\n

Dilema alegerii<\/h3>\n

\n\u00cen realitate, alegerea s-a dovedit a fi surprinz\u0103tor de simpl\u0103. Bine\u00een\u021beles, gusturile \u0219i culorile sunt diferite, a\u0219a c\u0103 criteriile \u0219i opiniile mele, relevante la acel moment, s-ar putea s\u0103 nu fie potrivite pentru tine. Mi-am amintit c\u00e2teva sisteme \u0219i voi descrie pe scurt g\u00e2ndurile mele despre ele.<\/p>\n

Ca administrator Windows, mi-a venit imediat \u00een minte System Center \u00een toat\u0103 splendoarea sa. Principalul avantaj este integrarea sa \u00een mediul Microsoft, f\u0103r\u0103 vr\u0103jitorie, ci nativ. Al doilea avantaj este abordarea complex\u0103. S\u0103 fim sinceri, System Center nu este doar un sistem de monitorizare; este, de fapt, un sistem de \u00eentre\u021binere a infrastructurii. Totu\u0219i, acesta este \u0219i primul dezavantaj. S\u0103 desfaci acest monstru doar pentru monitorizare nu are sens. Dac\u0103 ar fi fost necesare diverse backup-uri \u0219i desf\u0103\u0219urarea a milioane de VDS... \u0218i costul implement\u0103rii nu este tocmai \u00eencurajator, c\u0103ci va trebui s\u0103 ne \u00eendatore\u0103m de dou\u0103 ori - mai \u00eent\u00e2i pentru licen\u021be, iar apoi pentru servere<\/a>, unde va locui.<\/p>\n

\u00cen continuare, s\u0103 ne \u00eentoarcem \u00een trecut cu Nagios. Sistemul a fost eliminat imediat, deoarece configurarea manual\u0103 a sistemului prin fi\u0219iere de configurare \u00eel face greu de \u00eentre\u021binut. Nu \u00eei judec pe cei care le plac acele mii de linii identice pentru a modifica un singur parametru, dar nu vreau s\u0103 fac asta nici eu.<\/p>\n

Zenoss. Un sistem excelent! Totul exist\u0103, totul este posibil, se configureaz\u0103 cu un nivel de dificultate acceptabil, dar este destul de greu. Nu aveam acelea\u0219i dimensiuni, nu am folosit niciodat\u0103 grupuri \u00eennodat. \u0218i motorul s-a dovedit a fi prea solicitat \u00een ceea ce prive\u0219te resursele. De ce? Ne-am dat seama c\u0103 nu merit\u0103.<\/p>\n

Zabbix - alegerea noastr\u0103. Ne-au atras cerin\u021bele sistemice destul de sc\u0103zute \u0219i simplitatea de lansare. De fapt, a durat doar c\u00e2teva minute. Am desc\u0103rcat imaginea pentru VMWare \u0219i am ap\u0103sat pe butonul \u201epornire\u201d a ma\u0219inii virtuale. Totul! \u00ce\u021bi voi mai spune, pentru nevoile noastre ar fi fost suficient acest \u201eimagine de start\u201d, de\u0219i cur\u00e2nd am desf\u0103\u0219urat totul a\u0219a cum trebuie.<\/p>\n

\u00cen lista ini\u021bial\u0103 a fost \u0219i Cacti, dar nu am ajuns niciodat\u0103 la el. Care este sensul, dac\u0103 Zabbix a decolat din prima \u0219i a pl\u0103cut tuturor? A\u0219a c\u0103 nu pot spune nimic despre Cacti.<\/p>\n

Dup\u0103 cele scrise<\/h3>\n

\nCompania \u00een care am implementat Zabbix a murit \u00een mod fericit. Proprietarul a spus \u201em-am s\u0103turat de tot, \u00eemi \u00eenchid afacerea\u201d, a\u0219a c\u0103 nu prea am ce povesti despre monitorizare. Ne-am uitat dup\u0103 servers<\/a>, dup\u0103 internet \u0219i tuneluri pe toate platformele \u0219i am adunat contoare de la imprimante.<\/p>\n

Apoi, \u00een via\u021ba mea a fost pe scurt PRTG. Dup\u0103 p\u0103rerea mea, func\u021bioneaz\u0103 excelent cu sistemele Windows, folose\u0219te un mecanism interesant pentru agen\u021bi \u0219i cost\u0103 bani serio\u0219i. Aceasta este o ideologie destul de trist\u0103 \u00een ceea ce prive\u0219te accesul la actualiz\u0103rile versiunii.<\/p>\n

Compania \u00een care lucrez acum folose\u0219te Zabbix. Nu a fost alegerea mea, dar m\u0103 bucur de asta \u0219i o sus\u021bin complet. Av\u00e2nd \u00een vedere starea sistemului de monitorizare \u00eenainte de venirea mea, aproape c\u0103 am recreat totul de la zero. A existat o con\u0219tientizare c\u0103 \u201efacem ceva \u00een mod gre\u0219it\u201d. \u0218i chiar s-a desf\u0103\u0219urat o nou\u0103 serverul<\/a> cu Zabbix, dar nu a existat nimeni care s\u0103 preia aceast\u0103 sarcin\u0103 \u0219i s\u0103 o duc\u0103 p\u00e2n\u0103 la cap\u0103t. Nu am atins \u00eenc\u0103 iluminarea complet\u0103 \u00een monitorizare, dar sper c\u0103 \u0219tim direc\u021bia. Procesul de a duce monitorizarea la ideal este interminabil, de\u0219i am formulat deja principalele teze pentru mine.
