Kuzinhlelo zamafu amakhulu, indaba yokulinganisa okuzenzakalelayo noma ukulinganisa umthwalo kuzinsiza zekhompyutha ibucayi kakhulu. U-Tionix (umthuthukisi kanye no-opharetha wezinsizakalo zamafu, ingxenye yeqembu lezinkampani ze-Rostelecom) naye uye wanakekela lolu daba.
Futhi, njengoba inkundla yethu eyinhloko yokuthuthukisa i-Openstack, futhi thina, njengabo bonke abantu, siyavilapha, kwanqunywa ukukhetha imojula esenziwe ngomumo esivele ifakiwe endaweni yesikhulumi. Ukukhetha kwethu kwawela ku-Watcher, esanquma ukuyisebenzisela izidingo zethu.
Okokuqala, ake sibheke imigomo nezincazelo.
Imigomo Nezincazelo
Injongo kuwumphumela ofundeka umuntu, obonakalayo futhi olinganisekayo okufanele uzuzwe. Kukhona isu elilodwa noma amaningi okufeza umgomo ngamunye. Isu wukuqaliswa kwe-algorithm ekwaziyo ukuthola isisombululo somgomo othile.
Isenzo kuwumsebenzi oyisisekelo oshintsha isimo samanje sensiza ephethwe eqondiwe yeqoqo le-OpenStack, njengokuthi: ukuthutha umshini obonakalayo (ukufuduka), ukushintsha isimo samandla se-node (change_node_power_state), ukushintsha isimo sesevisi ye-nova (change_nova_service_state) ), ukushintsha ukunambitheka (ukushintsha usayizi), ukubhalisa imilayezo ye-NOP (nop), ukuntuleka kwesenzo sobude besikhathi esithile - misa isikhashana (ukulala), ukudluliswa kwediski (ivolumu_migrate).
Uhlelo lokusebenza - ukugeleza okuthile kwezenzo ezenziwa ngendlela ethile ukuze kuzuzwe umgomo othile. I-Action Plan futhi iqukethe ukusebenza okulinganiselwe komhlaba wonke ngesethi yezinkomba zokusebenza. Uhlelo lokusebenza lwenziwa i-Watcher lapho kucwaningwa kwamabhuku ngempumelelo, ngenxa yalokho isu elisetshenzisiwe lithola isisombululo sokufeza umgomo. Uhlelo lokusebenza luqukethe uhlu lwezenzo ezilandelanayo.
Audit kuyisicelo sokuthuthukisa iqoqo. Ukuthuthukisa kwenziwa ukuze kufezwe Umgomo owodwa kuqoqo elithile. Ekucwaningweni ngakunye okuyimpumelelo, i-Watcher yenza i-Action Plan.
Audit Scope isethi yezinsiza lapho ukucwaninga kwenziwa khona (izindawo ezitholakalayo), izihlanganisi zezindawo, izindawo zokubala ezingazodwana noma izindawo zokugcina, njll.). Ububanzi bokuhlola buchazwe kusifanekiso ngasinye. Uma ngabe i-audit scope ingacacisiwe, lonke iqoqo liyacwaningwa.
Audit Isifanekiso — isethi egciniwe yezilungiselelo zokuqalisa ukuhlola. Izifanekiso ziyadingeka ukuze wenze ukuhlola izikhathi eziningi ngezilungiselelo ezifanayo. Isifanekiso kufanele sibe nenhloso yocwaningo, uma amasu engacacisiwe, bese kukhethwa amasu akhona afaneleka kakhulu.
Iqoqo iqoqo lemishini ephathekayo ehlinzeka ngekhompyutha, isitoreji, nezinsiza zokuxhumana futhi ephethwe inodi yokuphatha ye-OpenStack efanayo.
Imodeli Yedatha Yeqoqo (CDM) ukumelwa okunengqondo kwesimo samanje kanye ne-topology yezinsiza eziphethwe yiqoqo.
Isikhombi Sokusebenza - inkomba ekhombisa ukuthi isixazululo esidalwe kusetshenziswa leli su senziwa kanjani. Izinkomba zokusebenza ziqondene ngqo nomgomo othile futhi ngokuvamile zisetshenziselwa ukubala ukusebenza kahle komhlaba wonke komphumela wohlelo lokusebenza.
Ukucaciswa Kokusebenza iyisethi yezici ezithile ezihlotshaniswa Nomgomo ngamunye ochaza izinkomba zokusebenza ezihlukahlukene okumele isu lokufinyelela Umgomo ohambisanayo lizifinyelele esixazululweni salo. Ngempela, isixazululo ngasinye esihlongozwe yisu sizohlolwa kuqhathaniswa nencazelo ngaphambi kokubala ukusebenza kwaso emhlabeni jikelele.
Injini Yokushaya iyifayela elisebenzisekayo elinokokufaka okuchazwe kahle, okuphumayo okuchazwe kahle, futhi lenza umsebenzi wezibalo kuphela. Ngale ndlela, ukubala kuzimele endaweni okwenziwa kuyo—kuzonikeza umphumela ofanayo noma kuphi.
Umhleli Wokubuka - ingxenye yenjini yokuthatha izinqumo. Le mojula ithatha isethi yezenzo ezikhiqizwe isu futhi idale uhlelo lokuhamba komsebenzi olucacisa indlela yokuhlela lezi zenzo ezihlukene ngesikhathi kanye nesenzo ngasinye, ukuthi iyini imibandela.

- Ekhasini Lokwenza Ukuthuthukisa - Izinhlelo ze-Action 500 (kokubili ku-Queens emsulwa kanye nesitendi esinamamojula we-Tionix), livela kuphela ngemva kokwethulwa kocwaningomabhuku kanye nohlelo lokusebenza; elingenalutho livuleka ngokujwayelekile.
- Kunamaphutha kuthebhu yemininingwane yesenzo, akwenzeki ukuthola umgomo wocwaningo kanye namasu (kokubili kumaQueens amsulwa kanye nesitendi esinamamojula we-Tionix).
- Ukucwaningwa kwamabhuku okunenjongo ye-Dummy (ukuhlola) kuyadalwa futhi kwethulwe ngokujwayelekile, kwenziwa izinhlelo zokusebenza.
- Ukuhlolwa komgomo Ongahlukaniswanga akudalwa ngenxa yokuthi umgomo awusebenzi futhi uhloselwe ukulungiselelwa okuphakathi lapho kwakhiwa amasu amasha.
- Ukuhlolwa kwenhloso Yokulinganisa Umthwalo Womsebenzi (Isu Lebhalansi Yekhono Lokulondoloza) kudalwe ngempumelelo, kodwa uhlelo lokusebenza alukhiqizwa. Akukho ukulungiselelwa kwephuli yesitoreji okudingekayo.
- Ukuhlolwa komgomo Wokulinganisa Umthwalo Womsebenzi (Isu Lokufuduka Kwebhalansi Yomthwalo Womsebenzi) kudalwe ngempumelelo, kodwa uhlelo lokusebenza alwenziwa.
- Ukuhlola Ukulinganisa Komthwalo Womsebenzi (Isu Lokuzinza Komthwalo Womsebenzi) kwehlulekile.
- Ukucwaningwa kwethagethi Yomakhelwane Onomsindo kudalwe ngempumelelo, kodwa uhlelo lwesenzo alwenziwa.
- Ukuhlolwa kwenhloso yokugcinwa kwe-Hardware kudalwe ngempumelelo, uhlelo lokusebenza alwenziwa ngokugcwele (izinkomba zokusebenza ziyakhiqizwa, kodwa uhlu lwezenzo ngokwalo alwenziwa).
- Ukuhlelwa ku-nova.conf configs (esigabeni esimisiwe compute_monitors = cpu.virt_driver) ku-comute nodes yokulawula awalungisi amaphutha.
- Ukucwaninga okuqondiswe ku-Server Consolidation (Isu eliyisisekelo) nakho kuyahluleka.
- Ukuhlolwa kwenhloso ye-Server Consolidation (isu lokuhlanganisa umthwalo we-VM) kwehluleka ngephutha. Kumalogu kunephutha ekutholeni idatha yomthombo. Ingxoxo yephutha, ikakhulukazi .
Sizamile ukucacisa i-Watcher kufayela lokumisa (akusizanga - ngenxa yephutha kuwo wonke amakhasi okuthuthukisa, ukubuyela kokuqukethwe kwangempela kwefayela lokumisa akusilungisi isimo): [watcher_strategies.basic] idathasource = i-ceilometer, i-gnocchi - Ukucwaningwa kwamabhuku okonga Amandla kwehlulekile. Uma sibheka izingodo, inkinga kusewukungabikho kwe-Ironic; ngeke isebenze ngaphandle kwenkonzo ye-baremetal.
- Ukucwaningwa kwe-Thermal Optimization kwehlulekile. I-traceback iyafana neye-Server Consolidation (isu lokuhlanganisa umthwalo we-VM) (iphutha ledatha yomthombo)
- Ukuhlolwa kwenhloso ye-Airflow Optimization kwehluleka ngephutha.
Amaphutha alandelayo okuphothula ukuhlola nawo ahlangatshezwane nawo. I-Traceback kumalogi e-decision-engine.log (isimo seqoqo asichazwanga).
→ Ingxoxo ngephutha
isiphetho
Umphumela wocwaningo lwethu lwezinyanga ezimbili kwaba isiphetho esingaguquki sokuthi ukuze sithole uhlelo olugcwele, olusebenzayo lokulinganisa umthwalo, sizoba, kule ngxenye, sisebenze eduze ekucwengisiseni amathuluzi epulatifomu ye-Openstack.
I-Watcher ibonakale ingumkhiqizo ongathi sína nothuthukayo ngokushesha onamandla amakhulu, ukusetshenziswa kwawo ngokugcwele okuzodinga umsebenzi omkhulu onzima.
Kodwa okwengeziwe ngalokhu ezihlokweni ezilandelayo zalolu chungechunge.
