Esihlokweni esilandelayo sizobheka i-Prometheus. Ingabe mayelana isoftware yamahhala nevulekile evumela ukuthi siqoqe amamethrikhi yezicelo zethu bese uzigcina ku-database. Luhlelo lokuqapha olulungele izindawo ezinamandla. I-Prometheus ibhalwe ku-Go. Izonikezela ngamamethrikhi we-CPU, inkumbulo, ukusetshenziswa kwediski, i-I / O, izibalo zenethiwekhi, iseva ye-MySQL neNginx.
Ukuqoqwa kwamamethrikhi okwenziwe ngu izinhloso ezibekiwe ngezikhathi ezithile. Ihlola izinkulumo zomthetho, ikhombisa imiphumela futhi ivumele ukwenza kusebenze izexwayiso uma kutholwa ukuthi noma yiziphi izimo ezichaziwe ziyiqiniso.
Kusukela yaqala ngonyaka we-2012, izinkampani nezinhlangano eziningi zikhethe ukusebenzisa iPrometheus. Ngaphezu kwalokho, iphrojekthi inomphakathi osebenzayo wabasebenzisi nabathuthukisi. Yiprojekthi yomthombo ovulekile ezimele ukuthi ihlala izimele kunoma iyiphi inkampani. Ukugcizelela lokhu, nokucacisa isakhiwo sokubusa sephrojekthi, uPrometheus wajoyina i- Isisekelo se-Cloud Native Computing ngo-2016 njengephrojekthi yesibili eyasingathwa, ngemuva Kubernetes.
Lolu hlelo lwenzelwe ukuthi lusetshenziswe ngesikhathi sokuphazamiseka, kusivumela ukuthi sihlolisise ngokushesha izinkinga ngedatha elisinikeza yona. Iseva ngayinye ye-Prometheus izimele, akuxhomekile kwisitoreji senethiwekhi noma kwamanye amasevisi akude. Yingakho singathembela kuyo lapho ezinye izingxenye zengqalasizinda yethu zehluleka.
Kumele kucaciswe ukuthi uma udinga ukunemba okungu-100%, njengokukhokha, i-Prometheus akuyona inketho enhle. Imininingwane eqoqiwe kungenzeka ayinemininingwane futhi igcwaliswe ngokwanele. Esimweni esinjalo, kungaba ngcono kunokusebenzisa olunye uhlelo ukuqoqa nokuhlaziya idatha yenkokhiso.
Izici ezijwayelekile ze-Prometheus
- Izosinikeza i- imodeli yedatha esezingeni eliphezulu kakhulu. Uchungechunge lwesikhathi lukhonjwa ngegama lenkomba kanye neqoqo lamanani wamanani wokhiye.
- Sizoba ne- kungenzeka ukusebenzisa ulimi lombuzo oluguquguqukayo, okuzosivumela ukuthi sisike futhi sisike idatha yochungechunge lwesikhathi esiqoqiwe ukukhiqiza amagrafu, amatafula kanye nezixwayiso ze-ad-hoc.
- Ngeke sithembele kwisitoreji esisatshalalisiwe.
- U-Prometheus une izindlela eziningi zokubonisa idatha- Isihloli samazwi esihlanganisiwe, ukuhlanganiswa kweGrafana, nolimi lwethempulethi lekhonsoli.
- Izitolo uchungechunge lwesikhathi kwimemori naku-disk yendawo, ngefomethi eyenziwe ngezifiso futhi esebenza kahle.
- Izexwayiso zichazwa ngokususelwa kulimi lombuzo oluguquguqukayo lwe-Prometheus futhi zigcina imininingwane yobukhulu. A umphathi wokuxwayisa usingatha izaziso futhi azithulise.
- I-Las imitapo yolwazi yamakhasimende vumela ukusetshenziswa kwezinsiza okulula. Imitapo yolwazi ngokwezifiso kulula ukuyisebenzisa.
- Abathengisi abakhona vele bavumela i- ukudala amabhuloho emininingwane nabantu besithathu.
para wazi okuningi ngalolu hlelo noma izici zalo ngokuningiliziwe, ungaxhumana ne- ikhasi le-GitHub leprojekthi.
Faka i-Prometheus
Ukufaka lolu hlelo ku-Ubuntu 18.04 kuqondile. Sizokwazi ifake kusuka kunketho yesoftware uhlelo olusebenzayo noma singadonsa ukuphela (Ctrl + Alt + T). Uma sikhetha le nketho yokufaka, ukuze siqale sibuyekeza uhlu lwesoftware etholakalayo. Sizoqhubeka nokufaka i-Prometheus ngokuthayipha umbhalo olandelayo:
sudo apt-get update -y && sudo apt-get install prometheus prometheus-node-exporter prometheus-pushgateway prometheus-alertmanager
Lapho ukufakwa sekuqediwe, singakwazi qala insiza lokho esisanda kukufaka.
sudo systemctl start prometheus
Singavumela ukuthi insizakalo iqala ngesikhathi sokuqala imishini ukuthayipha:
sudo systemctl enable prometheus
Sizokwazi hlola isimo sesevisi ngomyalo olandelayo:
sudo systemctl status prometheus
Finyelela ku-Prometheus
Ngemuva kokufakwa, sizothola ukuthi uhlelo lalela ethekwini 9090. Manje kufanele sivule isiphequluli sethu sewebhu futhi bhala i-URL http: // your-server-ip: 9090. Uzoqondiswa kabusha ekhasini eliyinhloko lapho singabuza khona.
Okulandelayo kuzoba umphumela wombuzo wedatha walesi sibonelo.
Ukusetshenziswa kangcono noma ukuxazulula noma ikuphi ukungabaza okungase kuvele ngesikhathi sokusebenzisa lolu hlelo, singaxhumana ne- imibhalo esizokuthola ekhasini elisemthethweni.
