\nTrebuie s\u0103 configur\u0103m echipamentul pentru monitorizare, iar \u00een sistemul nostru preferat Zabbix nu exist\u0103 un \u0219ablon preg\u0103tit pentru acest tip de echipament. Situa\u021bie cunoscut\u0103? Fiecare se descurc\u0103 cum poate. Un administrator caut\u0103 solu\u021bii pe internet.

Acum, echipa Zabbix extinde setul de \u0219abloane preinstalate cu fiecare nou\u0103 versiune. De exemplu, \u00een versiunea 5.0, care va fi lansat\u0103 \u00een cur\u00e2nd, va ap\u0103rea un nou \u0219ablon universal pentru monitorizare. servere<\/a> prin IPMI \u2014 Template Server by IPMI. Colegii m-au rugat s\u0103 \u00eei ajut s\u0103-l configureze pentru echipamente de la diferi\u021bi furnizori. Pentru noi, aceasta reprezint\u0103 o oportunitate unic\u0103 de a testa noua func\u021bionalitate. V\u0103 \u00eemp\u0103rt\u0103\u0219im rezultatele.

Cum arat\u0103 noul \u0219ablon? <\/h2>\n

\nPentru a putea monitoriza serverul dvs. folosind acest \u0219ablon, trebuie s\u0103 crea\u021bi \u00een sistem un \"nod de re\u021bea\" cu monitorizarea configurat\u0103 prin IPMI \u0219i s\u0103 ata\u0219a\u021bi \u0219ablonul Template Server by IPMI (Fig. 1). Aici nu va exista o descriere detaliat\u0103 a acestei opera\u021biuni: instruc\u021biuni detaliate sunt disponibile \u00een documenta\u021bia oficial\u0103 Zabbix.<\/p>\n

Fig. 1. \u0218ablon Template Server by IPMI<\/p>\n

\"Zabbix
\nS\u0103 examin\u0103m principiile de func\u021bionare ale acestui \u0219ablon \u0219i structura sa.<\/p>\n

Baza \u0219ablonului este utilitarul ipmitool. Acesta permite ob\u021binerea statisticilor necesare de la echipament prin IPMI. Utilizarea acestei func\u021bionalit\u0103\u021bi \u0219i ob\u021binerea tuturor datelor necesare sunt acum disponibile utilizatorului prin intermediul interfe\u021bei web, folosind tipul de elemente de date IPMI agent \u0219i cheia special\u0103 ipmi.get. Acest lucru a devenit posibil doar datorit\u0103 introducerii cheii ipmi.get \u00een noua versiune.<\/p>\n

\u00cen \u0219ablonul Template Server by IPMI, organizarea colect\u0103rii informa\u021biilor prin aceast\u0103 nou\u0103 func\u021bionalitate este realizat\u0103 de elementul de date Item Get IPMI sensors (Fig. 2).<\/p>\n

Fig. 2. Element de date Item Get IPMI sensors<\/p>\n

\"Zabbix
\nCa urmare a func\u021bion\u0103rii elementului de date Item Get IPMI sensors, \u00een sistemul Zabbix apare informa\u021bia despre starea echipamentului \u00eentr-un format JSON structurat (Fig. 3).<\/p>\n

Fig. 3. Exemplu de rezultat al elementului Get IPMI sensors<\/p>\n

\"Zabbix
\nPe l\u00e2ng\u0103 elementul de date Item Get IPMI sensors din \u0219ablon, exist\u0103 \u0219i dou\u0103 reguli de descoperire: Discrete sensors discovery (Fig. 4) \u0219i Threshold sensors discovery (Fig. 5). Aceste reguli de descoperire utilizeaz\u0103 JSON-ul ob\u021binut ca rezultat al func\u021bion\u0103rii elementului de date Item Get IPMI sensors pentru a crea automat noi elemente de date \u0219i triggere. Acest lucru este evident \u00een imaginile de mai jos din sec\u021biunea Master item.<\/p>\n

Fig. 4. Regula de descoperire Discrete sensors discovery<\/p>\n

\nFig. 5. Regula de descoperire Threshold sensors discovery<\/p>\n

\"Zabbix
\nDe ce sunt utilizate dou\u0103 reguli de descoperire \u00een \u0219ablon, \u0219i nu una? <\/p>\n

Discrete sensors discovery asigur\u0103 crearea automat\u0103 a elementelor de date care au tipul \u201estring\u201d \u00een valorile lor. Iar regula de descoperire Threshold sensors discovery permite crearea automat\u0103 de elemente de date care au tipul \u201enum\u0103r\u201d \u00een valorile lor. De asemenea, aceast\u0103 regul\u0103 poate genera pentru fiecare element de date p\u00e2n\u0103 la 6 triggere (Fig. 6).<\/p>\n

Valorile pentru condi\u021biile trigg\u0103rilor sunt preluate din JSON, adic\u0103 de la dispozitivul \u00een sine. Triggerele sunt create pentru 6 praguri: inferior periculos, inferior critic, inferior non-critic, superior non-critic, superior critic, superior periculos. Dac\u0103 valoarea pentru un prag lipse\u0219te \u00een JSON, triggerul nu este creat.<\/p>\n

\u00cen triggerul generat, pragul poate fi redefinit la nivelul Zabbix. Cu toate acestea, din punctul nostru de vedere, cea mai logic\u0103 modalitate de a modifica triggerul este s\u0103-l transformi la nivelul echipamentului. Cum se face acest lucru este de obicei indicat \u00een instruc\u021biunile dispozitivului.<\/p>\n

\nHai s\u0103 ne punem \u00een mi\u0219care!<\/strong><\/p>\n

Pentru a testa \u0219ablonul Template Server by IPMI, am ales servere de la trei produc\u0103tori: IBM, HP \u0219i Huawei. La c\u00e2teva minute dup\u0103 conectare, au fost ob\u021binute rezultate, prezentate \u00een tabel. <\/p>\n

\u0218ablonul Template Server by IPMI s-a dovedit a fi foarte eficient. A fost simplu de utilizat \u0219i, cel mai important, \u2014 \u201euniversal\u201d. <\/p>\n

\u0218ablonul Template Server by IPMI va fi inclus \u00een lista de \u0219abloane de baz\u0103 ale versiunii Zabbix 5.0. Din partea noastr\u0103, sus\u021binem pe deplin aceast\u0103 abordare a produc\u0103torului. Chiar dac\u0103 speciali\u0219tii sunt nevoi\u021bi s\u0103 creeze \u0219abloane specializate, recomand\u0103m s\u0103 se aib\u0103 ca baz\u0103 abord\u0103rile stabilite de c\u0103tre produc\u0103tor \u0219i care sunt observate \u00een Template Server by IPMI. \u00cen primul r\u00e2nd, folosirea detect\u0103rii automate a elementelor de date cu ajutorul item-ului principal. \u00cen al doilea r\u00e2nd, aplicarea detect\u0103rii automate a trigger-urilor folosind item-ul principal, acolo unde este posibil.<\/p>\n

De asemenea, a\u0219tept\u0103m cu ner\u0103bdare lansarea Zabbix 5.0 \u00een cur\u00e2nd!<\/p>\n
