Waa maxay Prometheus iyo maxaad ugu baahan tahay? Prometheus waa nidaam korjoogteyn awood leh kaas oo aruuriya oo socodsiiya xogta tirada (metrics) ee codsiyada. Waxay kaa caawinaysaa inaad la socoto tilmaamayaasha muhiimka ah sida: Tirada codsiyada uu qabtay adeeggaagu. Waqtiga jawaabta codsi kasta. Isticmaalka xusuusta iyo CPU. Tirada khaladaadka ka dhaca nidaamka Adigoo isticmaalaya Prometheus, waxaad ka jawaabi kartaa su'aalaha muhiimka ah sida: "Adeegaygu si hufan ma u shaqaynayaa?" "Waa maxay caqabadaha wax qabadku?" "Miyaan u baahanahay inaan kor u qaadno kaabayaashayaga?" Oo sidee buu Prometheus u ururiyaa cabbirada? Waxaa jira laba siyaabood oo aasaasiga ah ee Prometheus u ururiyo xogta: - Prometheus waxay si firfircoon u waydiisaa adeegyada cabbirkooda. Qaabka Jiid - Adeegyadu waxay ku riixaan cabbirkooda dhexdhexaadiyaha, kaas oo Prometheus uu markaa ururiyo. Habka riix (Pushgateway) Aynu kala jebinno. Jiid Model , Prometheus cabbirada codsigaaga HTTP (tusaale, ). Qaabka jiidashada wuxuu si firfircoon uga soo saarayaa http://your-service:8080/metrics Kani waa habka caadiga ah oo inta badan la isticmaalo. Dejinta Prometheus leh Golang (Model Jiid) Ku rakib maktabadaha lagama maarmaanka ah: go get github.com/prometheus/client_golang/prometheus go get github.com/prometheus/client_golang/prometheus/promhttp (tusaale, tirinta codsiyada HTTP): Qeex cabbirkaaga import ( "github.com/prometheus/client_golang/prometheus" "github.com/prometheus/client_golang/prometheus/promauto" ) var httpRequestsTotal = promauto.NewCounter(prometheus.CounterOpts{ Name: "http_requests_total", Help: "Total number of HTTP requests", }) barta dhamaadka : Soo bandhig /metrics import ( "net/http" "github.com/prometheus/client_golang/prometheus/promhttp" ) func main() { http.Handle("/metrics", promhttp.Handler()) } : Ku xidh Prometheus si aad u xoqdo mitirka adeegaaga prometheus.yml scrape_configs: - job_name: "example_service" static_configs: - targets: ["localhost:8080"] Hadda, Prometheus wuxuu si toos ah u waydiin doonaa dhowr ilbiriqsi kasta si uu u ururiyo xogta. http://localhost:8080/metrics Waa maxay sababta Model-jiidka loo door biday? - Prometheus waxay xakameysaa jadwalka xoqidda iyo inta jeer. Fududeynta - Looma baahna adeeg dheeraad ah si loo helo cabbirro. Dhibco yar oo guuldarro ah - Haddii adeeggu joojiyo ka jawaabista, Prometheus wuxuu si fudud u joojiyaa helitaanka xogta, isaga oo iska ilaalinaya cabbirada taagan. Nadiifin toos ah Qaabka Riixitaanka (Pushgateway Approach) , adeeggu wuxuu u mitirkiisa adeeg dhexdhexaad ah oo la yiraahdo , kaas oo kaydiya ilaa Prometheus ka soo qaado. Qaabka riixitaanka soo diraa Pushgateway Sida ay u shaqeyso (Modelka riix) Codsigaagu Pushgateway: wuxuu u riixaa cabbirada import ( "github.com/prometheus/client_golang/prometheus" "github.com/prometheus/client_golang/prometheus/push" ) func main() { registry := prometheus.NewRegistry() jobCounter := prometheus.NewCounter(prometheus.CounterOpts{ Name: "job_execution_count", Help: "Number of executed jobs", }) registry.MustRegister(jobCounter) jobCounter.Inc() err := push.New("http://localhost:9090", "my_service_or_job"). Collector(jobCounter). Grouping("instance", "worker_1"). Push() if err != nil { panic(err) } } Habee Prometheus si aad xogta uga soo ururiso Pushgateway: scrape_configs: - job_name: "pushgateway" static_configs: - targets: ["localhost:9091"] Goorma ayuu Faa'iido u leeyahay Qaabka Riixa? Dhab ahaantii ee dhammaystira ka hor inta uusan Prometheus xoqin. Shaqooyinka muddada-gaaban (hawlaha dufcadda, shaqooyinka cron) halka Prometheus uusan si toos ah u heli karin adeega. Xayiraadaha shabakada (qalabka IoT, API-yada dibadda) ee aan si toos ah loo xoqin karin. Ilaha xogta dibadda Qaabkee Aad Isticmaalaysaa? Habka Waxa ugu fiican... Faa'iidooyinka Qasaarooyinka Jiid (la taliyay) Adeegyada shabakadda, API-yada, codsiyada muddada dheer socda Habaynta fudud, ku tiirsanaanta yar, nadiifinta tooska ah Aan ku habboonayn hawlo aad u gaaban Riix (Pushgateway) Shaqooyinka Dufcadaha, hawlo aan lahayn marin shabakad deggan Oggolow riixitaanka xogta shaqooyinka muddada gaaban Xogta duugan, kakanaanta dheeraadka ah, khatarta carqaladaha Maxay tahay sababta riixitaanka Modelku ugu habboonayn? In kasta oo ay xalliso dhibaatooyinka qaarkood (tusaale, geeddi-socodyada muddada-gaaban ee dhammaanaya ka hor inta uusan Prometheus xoqin), waxay : Pushgateway soo bandhigaysaa dhowr arrimood oo cusub Way adag tahay in la maareeyo xogta duugowday Haddii adeeggu dhinto, cabbirkiisii hore ayaa ku hadhaya Pushgateway. Prometheus ma laha hab lagu ogaado haddii adeeggu wali socdo. Waa inaad gacanta ku tirtirtaa cabbirada duugoobay addoo isticmaalaya ama dejiso siyaasadaha dhicitaanka. push.Delete(...) Kakanaanta dheeraadka ah Halkii laga heli lahaa isku xirka, waxaad hadda haysataa . Adeeg toos ah → Prometheus Adeeg → Pushgateway → Prometheus Pushgateway waa ku-tiirsanaan dheeraad ah, kor u kaca dayactirka. Caqabado iman kara Haddii adeegyo badani ay si joogto ah u riixaan cabbirada, Pushgateway waxay noqon kartaa culays. Si ka duwan sida tooska ah ee Prometheus xoqid (kaas oo qaybiya culeyska), dhammaan codsiyada waxay ku dhufteen hal tusaale oo Pushgateway ah. Arrimaha joogtaynta xogta Haddii adeegyo badan ay riixaan mitiro isku magac leh laakiin qiimayaal kala duwan, xogta ayaa laga yaabaa in dib loo qoro, taasoo keenta natiijooyin khaldan. Gabagabo Prometheus waa qalab awood leh oo la isku halayn karo oo loogu talagalay la socodka adeegyada. Codsiyada intooda badan, ayaa ah doorashada ugu fiican-waa mid fudud, hufan, oo hubisa xogta cusub iyada oo aan la helin kakanaanta dheeraadka ah. Si kastaba ha ahaatee, haddii aad la shaqaynayso sida hawlaha Lambda ama shaqooyinka dufcadda, ee loo maro Pushgateway ayaa faa'iido u yeelan kara in la qabto cabbirka ka hor inta aan hawsha bixin. qaabka jiidashada geeddi-socod gaaban qaabka riixitaanka Doorashada habka saxda ah waxay xaqiijinaysaa u fiirsashada wanaagsan iyo joogteynta nidaamkaaga. Iska ilaali!
