\nBeh\u00f6ver du \u00f6vervaka utrustning, men det finns ingen f\u00e4rdig mall f\u00f6r den h\u00e4r typen av utrustning i det \u00e4lskade systemet Zabbix? K\u00e4nns det bekant? Alla hanterar det p\u00e5 sitt s\u00e4tt. En administrat\u00f6r s\u00f6ker l\u00f6sningar p\u00e5 internet. En annan utvecklar sin egen. Och vissa sl\u00e4pper helt enkelt taget. Just nu ut\u00f6kar Zabbix-teamet med varje ny version antalet f\u00f6rinstallerade mallar i systemet. Till exempel kommer den kommande versionen 5.0 att ha en ny universell mall f\u00f6r \u00f6vervakning servrar<\/a> via IPMI \u2014 Template Server by IPMI. Mina kollegor bad om hj\u00e4lp med att st\u00e4lla in dess funktionalitet p\u00e5 utrustning fr\u00e5n olika tillverkare. F\u00f6r oss \u00e4r detta ocks\u00e5 en unik m\u00f6jlighet att prova den nya funktionaliteten. Vi delar resultatet.
\n<\/a><\/noindex><\/p>\n

Hur ser den nya mallen ut? <\/h2>\n

\nF\u00f6r att kunna \u00f6vervaka din server med hj\u00e4lp av denna mall beh\u00f6ver du skapa en \"n\u00e4tverksnod\" i systemet med konfigurerad \u00f6vervakning via IPMI och koppla mallen Template Server by IPMI till den (Bild 1). H\u00e4r kommer ingen detaljerad beskrivning av denna operation: en detaljerad guide finns i den officiella dokumentationen f\u00f6r Zabbix.<\/p>\n

Bild 1. Mall Template Server by IPMI<\/p>\n

\"Zabbix
\nL\u00e5t oss titta p\u00e5 mallen och dess struktur.<\/p>\n

Grunden f\u00f6r mallen \u00e4r verktyget ipmitool. Det m\u00f6jligg\u00f6r att f\u00e5 n\u00f6dv\u00e4ndig statistik fr\u00e5n utrustning via IPMI. Anv\u00e4ndningen av detta verktygs funktionalitet och att f\u00e5 alla n\u00f6dv\u00e4ndiga data \u00e4r nu tillg\u00e4ngligt f\u00f6r anv\u00e4ndare via webgr\u00e4nssnittet med hj\u00e4lp av datatyperna IPMI agent och den speciella nyckeln ipmi.get. Detta har blivit m\u00f6jligt tack vare inf\u00f6randet av nyckeln ipmi.get i den nya versionen.<\/p>\n

I mallen Template Server by IPMI ansvarar datakomponenten Item Get IPMI sensors (Bild 2) f\u00f6r organisationen av insamlingen av information med hj\u00e4lp av denna nya funktionalitet.<\/p>\n

Bild 2. Datakomponenten Item Get IPMI sensors<\/p>\n

\"Zabbix
\nSom ett resultat av arbetet med datakomponenten Item Get IPMI sensors dyker information om utrustningens skick upp i Zabbix-systemet i ett strukturerat JSON-format (Bild 3).<\/p>\n

Bild 3. Exempel p\u00e5 resultatet av item Get IPMI sensors<\/p>\n

\"Zabbix
\nF\u00f6rutom datatelementet Item Get IPMI sensors finns det \u00e4ven tv\u00e5 uppt\u00e4cktsregler i mallen: Discrete sensors discovery (Fig. 4) och Threshold sensors discovery (Fig. 5). Dessa uppt\u00e4cktsregler anv\u00e4nder JSON som genereras av datatelementet Item Get IPMI sensors f\u00f6r att automatiskt skapa nya datatelement och triggers. Detta framg\u00e5r tydligt i figurerna nedan i avsnittet Master item.<\/p>\n

Fig. 4. Uppt\u00e4cktsregeln Discrete sensors discovery<\/p>\n

\nFig. 5. Uppt\u00e4cktsregeln Threshold sensors discovery<\/p>\n

\"Zabbix
\nVarf\u00f6r anv\u00e4nds tv\u00e5 uppt\u00e4cktsregler i mallen ist\u00e4llet f\u00f6r en? <\/p>\n

Discrete sensors discovery m\u00f6jligg\u00f6r automatiskt skapande av datatelement som har typen \"str\u00e4ng\" i sina v\u00e4rden. \u00c5 andra sidan m\u00f6jligg\u00f6r uppt\u00e4cktsregeln Threshold sensors discovery automatiskt skapande av datatelement som har typen \"nummer\" i sina v\u00e4rden. Dessutom kan denna regel skapa upp till 6 triggers f\u00f6r varje datatelement (Fig. 6).<\/p>\n

V\u00e4rdena f\u00f6r triggervillkoren h\u00e4mtas fr\u00e5n JSON, det vill s\u00e4ga fr\u00e5n enheten sj\u00e4lv. Triggers skapas f\u00f6r 6 tr\u00f6sklar: nedre farliga, nedre kritiska, nedre icke-kritiska, \u00f6vre icke-kritiska, \u00f6vre kritiska och \u00f6vre farliga. Om v\u00e4rdet f\u00f6r n\u00e5gon tr\u00f6skel saknas i JSON, skapas inte triggern.<\/p>\n

I den skapade triggern kan tr\u00f6skeln \u00e5sidos\u00e4ttas p\u00e5 Zabbix-niv\u00e5. Men enligt v\u00e5r \u00e5sikt \u00e4r det mest logiska s\u00e4ttet att \u00e4ndra triggern att g\u00f6ra det p\u00e5 enhetsniv\u00e5. Hur detta vanligtvis g\u00f6rs anges vanligtvis i enhetens instruktioner.<\/p>\n

F\u00f6r att testa mallen Template Server by IPMI valde vi servrar fr\u00e5n tre tillverkare: IBM, HP och Huawei. N\u00e5gra minuter efter anslutningen fick vi resultat som anges i tabellen. <\/p>\n

\nAll utrustning lyckades \u00f6vervakas med hj\u00e4lp av den nya mallen och den nya nyckeln ipmi.key.<\/p>\n

Vi kunde f\u00e5 mest data fr\u00e5n Huaweis utrustning, och minst fr\u00e5n HP. Anledningen till detta ligger i skillnaderna i h\u00e5rdvaran och har inget att g\u00f6ra med kvaliteten p\u00e5 den nya mallen.<\/p>\n

P\u00e5 sk\u00e4rmdumparna nedan kan du se automatiskt skapade datatelement och triggers fr\u00e5n mallen. <\/p>\n

Mallen Template Server by IPMI har visat sig vara utm\u00e4rkt. Den \u00e4r enkel att anv\u00e4nda och, viktigast av allt, \"universell\". <\/p>\n

Mallen Template Server by IPMI kommer att ing\u00e5 i listan \u00f6ver grundmallar i version Zabbix 5.0. Vi st\u00f6der helt detta tillv\u00e4gag\u00e5ngss\u00e4tt fr\u00e5n tillverkaren. \u00c4ven om specialister m\u00e5ste skapa sina egna specialiserade mallar, rekommenderar vi att de utg\u00e5r fr\u00e5n de tillv\u00e4gag\u00e5ngss\u00e4tt som tillverkaren sj\u00e4lv har lagt grunden f\u00f6r och som observeras i Template Server by IPMI. F\u00f6r det f\u00f6rsta, anv\u00e4nd automatisk uppt\u00e4ckte av datatelement med hj\u00e4lp av master item. F\u00f6r det andra, till\u00e4mpa automatisk uppt\u00e4ckte av triggers med hj\u00e4lp av master item d\u00e4r s\u00e5 \u00e4r m\u00f6jligt.<\/p>\n

Och vi ser fram emot lanseringen av Zabbix 5.0 inom kort!<\/p>\n
