Iyini "i-watchdog" kukhompuyutha yezimboni?
Isifinyezo solwazi:
Lapho ezinye izinkampani zidinga ukuthenga amakhompyutha ezimboni, ngokuvamile zidinga imishini ukuze isebenze amahora angu-7*24 ngosuku, kodwa ngesikhathi sokusebenza komshini, akunakugwemeka ukuthi umshini uzophahlazeka noma ungene ku-loop efile. I-watchdog izosetha kabusha ikhompuyutha yezimboni ukuze ibuyisele esimweni esejwayelekile; ake ngethule ukuthi iyini inja ngokuningiliziwe ngezansi?
Okuqukethwe
- 1. Isingeniso se-"watchdog"
- 2. Uyini umgomo wokusebenza "we-watchdog"
- 3. Iyiphi indima edlalwa "i-watchdog" kumakhompyutha ezimboni
- 4. Hlobo luni lwezinkampani ezizodinga ukusebenzisa i-"watchdog"
- 5. Isiphetho
1. Isingeniso se-"watchdog"
I-watchdog kukhompyutha yezimboni wuhlelo olusetshenziswa kakhulu ukuhlola njalo isimo sangaphakathi sekhompyutha yezimboni. Uma iphutha noma okungavamile kutholakele, inja izothumela isignali yokuqalisa kabusha kukhompuyutha yezimboni ukuze izame ukubuyisela isimo esivamile sokusebenza.
2. Uyini umgomo wokusebenza "we-watchdog"
I-watchdog ikakhulukazi ihilela izingxenye ezimbili, i-monitor kanye ne-timer. Imonitha inesibopho sokuhlola isimo sekhompuyutha yezimboni, okuhlanganisa ukusetshenziswa kwe-CPU, ukusetshenziswa kwememori, isikhala sediski eliqinile, ukuxhumeka kwenethiwekhi, njll. Isibali sikhathi sizoqala ukubeka isikhathi lapho isistimu iqala, futhi lapho isibali sikhathi siphela, indlela yokuvikela inja yokubuka izoqaliswa. Ekusetshenzisweni okukhethekile, i-watchdog ingasetshenziswa ngehadiwe noma isoftware.
3. Iyiphi indima edlalwa "i-watchdog" kumakhompyutha ezimboni
Okokuqala, i-watchdog ingahlola njalo isimo sangaphakathi sekhompuyutha yemboni, okuhlanganisa isimo sezingxenyekazi zekhompuyutha, isimo sesofthiwe, njll. Uma okungavamile noma iphutha kutholakele, njenge-runaway program noma i-dead loop, i-watchdog izosetha kabusha ikhompyutha yemboni ngokushesha ukuze iyibuyisele esimweni esivamile sokusebenza.
Okwesibili, i-watchdog ingamelana nokuphazanyiswa yizwe langaphandle. Ngesikhathi sokusebenza kwekhompiyutha yezimboni, ivamise ukuphazanyiswa yizinto ezihlukahlukene zangaphandle, njengokuhluleka kwamandla, ukuphazamiseka kwenkundla kazibuthe, njll. Lokhu kuphazamiseka kungase kubangele amaphutha esikhombi sohlelo, kukhiphe imiyalelo yohlelo olungalungile, nezinye izinkinga, okuzobangela ukuthi uhlelo lungene esimweni esingalindelekile. Njengesilinganiso sokuvikela ihadiwe, umlindi angakwazi ukuqapha ngempumelelo isimo sesistimu, abone izinkinga ngesikhathi futhi athathe izinyathelo zokuvikela ezihambisanayo ukuze agweme ukuphahlazeka kwesistimu noma imiphumela engalindelekile.
Ngokufigqiwe, indima ye-watchdog kukhompyutha yezimboni ukuvikela ukusebenza okuzinzile kwesistimu, ukuthola izinkinga ngesikhathi futhi uthathe izinyathelo ezihambisanayo ukuze ugweme imiphumela engalindelekile yesistimu.
4. Hlobo luni lwezinkampani ezizodinga ukusebenzisa i-"watchdog"
(1) Izinkampani ezikhiqizayo: Lezi zinkampani ngokuvamile zidinga ukuqapha amathuluzi ukuvimbela ukungasebenzi kwemishini okuholela ekuphazamisekeni kokukhiqiza. Ama-watchdogs angakwazi ukubona ukwehluleka kwemishini ngesikhathi futhi aqale kabusha ngokuzenzakalelayo umshini ukuze aqinisekise ukusebenza okuzinzile komugqa wokukhiqiza.
(2) Izinkampani ezidayisayo: Izinkampani ezithengisayo zidinga ukuqapha i-inventory kanye nokuthengisa ukuze zigweme ukulahlekelwa yizimpahla noma ukuthengiswa okungavamile. Ama-Watchdogs angaqapha idatha yokuthengisa kanye ne-inventory ukuze athole okungavamile ngesikhathi futhi athathe izinyathelo ezihambisanayo.
(3) Izikhungo zezimali: Izikhungo zezezimali zidinga ukuqinisekisa ukunemba nokuvikeleka kwemisebenzi ukuze zigweme amaphutha okwenziwayo noma ukuba sengozini kwezokuvikela. Ama-Watchdogs angaqapha idatha yokwenziwayo, abone ukuthengiselana okungavamile ngesikhathi futhi athathe izinyathelo zokuphepha ezihambisanayo.
(4) Izikhungo zezokwelapha: Izikhungo zezokwelapha zidinga ukuqinisekisa ukusebenza okuzinzile kwemishini yezokwelapha ukugwema izingozi zezokwelapha. Abaqaphi bangakwazi ukuqapha isimo sokusebenza semishini yezokwelapha, babone amaphutha ngesikhathi futhi bathathe izinyathelo ezihambisanayo.
(5) Izinkampani ezisebenzela umphakathi: Lezi zinkampani kumele ziqinisekise ukusebenza okuzinzile kwengqalasizinda ukugwema umthelela emphakathini. Abaqaphi bangakwazi ukuqapha isimo sengqalasizinda, babone amaphutha ngesikhathi futhi bathathe izinyathelo ezihambisanayo.
5. Isiphetho
I-SINSMART Industrial Control ikholelwa ngokuqinile ukuthi ngokuqunga isibindi kuphela lapho singakwazi ukubona ukukhanya, futhi ngokuqunga isibindi sokusungula izinto ezintsha nokuzijwayeza lapho singanikeza amakhasimende imikhiqizo engcono. Sihlala sizisekela ezidingweni zamakhasimende futhi sinikeza uhla olugcwele lwamakhompiyutha ezimboni ezinokwethenjelwa kakhulu nezixazululo zokulawula izimboni.
