CPUTool - Oke na jikwaa ojiji CPU nke usoro ọ bụla na Linux
Otu n'ime mpaghara dị oke egwu n'okpuru ngwaọrụ nleba anya arụmọrụ Linux iji leba anya ka ihe na-apụta na sistemụ.
Ọtụtụ n'ime ngwaọrụ ndị a na-ewepụta steeti/ọnụ ọgụgụ sistemụ ebe ole na ole ndị ọzọ na-enye gị ụzọ ijikwa arụmọrụ sistemụ. Otu ngwa a na-akpọ CPUTool.
CPUTool bụ ngwa ahịrị iwu dị mfe ma dị ike maka ịmachi na ịchịkwa ojiji CPU nke usoro ọ bụla na oke enyere ma na-enye ohere nkwụsị nke mmezu usoro ma ọ bụrụ na ibu sistemu gafere oke akọwapụtara.
Iji gbochie ojiji CPU, cputool na-eziga akara SIGSTOP na SIGCONT na usoro na nke a na-ekpebi site na ibu sistemu. Ọ dabere na /proc pseudo-filesystem ka ịgụọ PID na usoro ojiji CPU ha.
Enwere ike iji ya belata ojiji CPU ma ọ bụ ibu sistemụ na-emetụta otu usoro ma ọ bụ otu usoro na oke enyere na/ma ọ bụ kwụsịtụ usoro ma ọ bụrụ na ibu sistemu gafere oke.
Wụnye CPUTool iji kpachie ojiji CPU na nkezi ibu
Otu CPUTool dị naanị iji wụnye na Debian/Ubuntu yana ihe ndị sitere na ebe nchekwa sistemụ ndabara site na iji ngwa njikwa ngwugwu.

Iji nyochaa ojiji CPU anyị nwere ike iji ngwaọrụ nlele nke na-enye anyị ohere ilele ọnọdụ a na-emelite oge niile nke usoro sistemụ Linux na-agba ọsọ:

# cputool --cpu-limit 50 -p 8275
Mgbe emechara cputool, anyị nwere ike ịlele ojiji CPU ọhụrụ maka usoro ahụ (PID 8275) ọzọ. Ugbu a ojiji CPU maka usoro dd kwesịrị ịdị na (49.0%-52.0%).

Maka ozi ndị ọzọ na ojiji, lelee ibe CPUTool man:
# man cputool
Lelee ntuziaka bara uru maka ịchọta ozi CPU na nlekota oru CPU:

- Cpustat – Na-enyocha ojiji CPU site na usoro ịgba ọsọ na Linux
- CoreFreq – Ngwá ọrụ nlekota CPU siri ike maka Sistemụ Linux
- Chọta usoro ịgba ọsọ kacha elu site na ebe nchekwa kacha elu yana ojiji CPU na Linux
Na mmechi, CPUTool na-abịa n'ezie maka njikwa arụmọrụ Linux. Kekọrịta echiche gị gbasara akụkọ a site na mpempe nzaghachi n'okpuru.
