Kwinqaku elilandelayo siza kujonga kwi-OProfile. Oku yi Iprofayile yokusebenza yeGnu / Linux. Usenokuzibuza ukuba kutheni ungasifuna isixhobo esinje kuba zininzi kakhulu izixhobo zohlalutyo ezisebenza kakuhle kakhulu kwaye ziyafumaneka ngokungagqibekanga kunikezelo oluninzi lweGnu / Linux. Le projekthi yomthombo ovulekileyo ebandakanya iprofayile yeenkcukacha manani yeenkqubo zeGnu / Linux, ezinakho yenza iiprofayili zayo yonke ikhowudi esebenzayo.
Le phakheji yezixhobo ezingasebenzi kuphela kuhlalutyo kwinqanaba elinzulu. Njengokuba igcina idatha kwaye isivumela ukuba sivelise ingxelo yokusebenza. Ezi ngxelo zibonelela ngobutyebi bolwazi olunokusinceda ukulungisa ingxaki kwaneyona ngxaki inzima yokusebenza.
I-OProfile sisixhobo esinamandla esiqhagamshela kwelona nqanaba lisezantsi lifumaneka kwiGnu / Linux ukufumana izinto zokubala zokusebenza kunye neemetriki eziya kuthi zisinike ulwazi oluxabisekileyo malunga neenkqubo zethu. Ngoku siyakwazi yazi ngokuchanekileyo ukuba yintoni inkqubo yethu eyenzayo kunye nendlela yokuphucula (ukuba sinolwazi oluyimfuneko). Ngokufunda iingxelo eziveliswe yi-OProfile, siya kuba nakho ukwenza izigqibo eziqhutywa yidatha ukulungisa inkqubo yethu.
Esi sicelo isebenzisa izixhobo zokubala zeCPU zokusebenza ukwenza ukuba ukubalwa kweenkcukacha-manani ezinomdla, ezinokusetyenziselwa ixesha elisisiseko elichithwe kwiprofayili. Yonke ikhowudi icacisiwe: izixhobo zekhompyutha kunye nokuphazamisa isoftware, iimodyuli zekernel, i-kernel, iilayibrari ekwabelwana ngazo kunye nokusetyenziswa. Siya kuba nayo vi-arias izixhobo zokwenza iprofayili yokuguqula idatha yeprofayile ibe lulwazi olunokufundeka ebantwini.
I-OProfile ayenzelwanga abaphuhlisi kuphela. Kwimeko ye desktop, i-OProfile ingasinceda ukulandelela imisebenzi yangasemva ye-CPU okanye iifowuni ze-I / O okucothisa inkqubo yethu kwaye akubonakali kwangoko. Oko kuthethiweyo, abaphuhlisi ngokuqinisekileyo baya kufumana okuninzi kwi-OProfile. Ngolwazi oluthe kratya malunga nenkqubo, nabani na oyifunayo unokuya kwi iwebhusayithi yeprojekthi.
Faka i-OProfile kwi-Ubuntu 17.10
Kukho inqaku elibaluleke kakhulu ekufuneka uligcinile engqondweni ngaphambi kokungena kwi-OProfile. Sisenokungakwazi ukuyifaka kwindawo ebonakalayo. Ukuba usebenzisa i-Gnu / Linux ngaphakathi kwe-VirtualBox, VMWare, okanye imeko efanayo ye-VM, i-OProfile ayinakho ukufikelela kwizibali zokusebenza ezifunekayo ukuqokelela idatha.
Izabelo ezininzi ze-Gnu / Linux zine-OProfile kwiinkqubo zazo zolawulo lweephakeji. Ukufakela le nkqubo kwi-Ubuntu 17.10 kuya kufuneka sivule i-terminal (Ctrl + Alt + T) kwaye ubhale:
sudo apt install oprofile
Umzekelo olula
Umyalelo "ls»Inokuba yeyona uyisebenzisa kakhulu ngexesha lakho phambi kweconsole. Ibonisa nje uluhlu lweefayile kunye neefolda kulawulo lwangoku. Siza kulanda iziphumo zayo ngokuchwetheza kwi-terminal (Ctrl + Alt + T):
sudo operf ls
Uza kubona into efana nekrini ephezulu. Nje ukuba iprofayile igqibe, i-terminal iyakusibonisa umyalezo «Ukwenza iprofayili kwenziwe«. Ezi datha zikhona igcinwe kwifowulda ebizwa ngokuba yifayile yedatha ebekwe kwikhaya lomsebenzisi enokusetyenziselwa ukwenza ingxelo.
Ukuqhuba i-opreport command (ngaphandle kwesudo kule meko) ivelisa ingxelo efana nale ilandelayo:
Kulo mzekelo, ingxelo emiselweyo ibonisa ifayile ye Inani leesampulu xa i-CPU yayingekho kwimeko ye-HALT (ngamanye amagama, bendisenza into ethile). kallsyms ibonelela ngophendlo lwesimboli olusetyenziswe ngumnxibelelanisi, kunye ld. ngoko y libc.so ziyinxalenye yephakheji ye-glibc. Le yokugqibela ilayibrari eqhelekileyo edityaniswe phantse kuzo zonke izinto ezinokwenziwa zeGnu / Linux. Ukubonelela ngokusebenza ngokusisiseko abanokuthi basebenzise ababoneleli ukubonelela ngenqanaba eliqhelekileyo lokuhambelana kwenkqubo yokuwela.
Amanyathelo ekufuneka elandelwe xa ugqibile
Nje ukuba sigqibe ngengxelo, ngumbono olungileyo cima ifolda yedatha okanye uyigcine kuhlalutyo lwexesha elizayo. Njengakulo mzekelo senza umthetho ngesudo, kufuneka sicime ifolda ngesudo.
sudo rm -Rf oprofile_data
Kubalulekile ukuba uqaphele ukuba nangona Inkangeleko ye-OP akufuneki iphazamisane nokusebenza kweenkqubo zakhoIya kwenza isentloko ngaphezulu. Ke ngoko iyakucothisa ukwenziwa kwezi. Ngenxa yale nto, Andiqondi ukuba licebo elilungileyo ukusebenzisa le nkqubo kwindawo yemveliso yeseva. Ngaphandle kokuba sijamelene nomcimbi osebenzayo obalulekileyo ekufuneka usonjululwe kwangoko. Kule meko, unokuyisebenzisa ixesha elide ngokwaneleyo ukufumana ingxaki.
Ukuba kukho umntu ofuna eminye imizekelo yezinto ezinokwenziwa ngale nkqubo, ungazijonga ukusuka kwiwebhusayithi esemthethweni yenziwe yafumaneka kubasebenzisi.
Khipha iOProfile
Siza kuba nakho ukuyiphelisa le nkqubo kwinkqubo yethu ngokuchwetheza kwi-terminal (Ctrl + Alt + T) oku kulandelayo:
sudo apt remove oprofile && sudo apt autoremove
