Ubuntu 12.10’da CPU Kullan\u0131m\u0131n\u0131 S\u0131n\u0131rlama Rehberi<\/h2>\n

Ubuntu 12.10, “Precise Pangolin” kod adl\u0131, LTS (Uzun S\u00fcreli Destek) olmayan bir s\u00fcr\u00fcm olmas\u0131na ra\u011fmen, bir\u00e7ok kullan\u0131c\u0131 i\u00e7in kararl\u0131 ve g\u00fcvenilir bir i\u015fletim sistemi deneyimi sunmu\u015ftur. G\u00fcncel olmasa da, bu s\u00fcr\u00fcmdeki sistem y\u00f6netimi prensipleri ve ara\u00e7lar\u0131, Linux tabanl\u0131 sistemlerde kaynak y\u00f6netimini anlamak i\u00e7in hala ge\u00e7erlidir. \u00d6zellikle eski donan\u0131mlarda veya belirli uygulamalar\u0131n CPU’yu a\u015f\u0131r\u0131 kullanmas\u0131n\u0131 engellemek istedi\u011finiz durumlarda, CPU kullan\u0131m\u0131n\u0131 s\u0131n\u0131rlamak hayati \u00f6nem ta\u015f\u0131yabilir. Bu teknik makale, Ubuntu 12.10 \u00fczerinde CPU kullan\u0131m\u0131n\u0131 nas\u0131l izleyece\u011finizi, sorunlu s\u00fcre\u00e7leri nas\u0131l belirleyece\u011finizi ve farkl\u0131 y\u00f6ntemlerle CPU kullan\u0131m\u0131n\u0131 nas\u0131l etkili bir \u015fekilde s\u0131n\u0131rlayaca\u011f\u0131n\u0131z\u0131 detayl\u0131 bir \u015fekilde a\u00e7\u0131klayacakt\u0131r.<\/p>\n

Neden CPU Kullan\u0131m\u0131n\u0131 S\u0131n\u0131rlamal\u0131y\u0131z?<\/h3>\n

CPU (Merkezi \u0130\u015flem Birimi), bilgisayar\u0131n\u0131z\u0131n beyni olup t\u00fcm hesaplama i\u015flemlerini y\u00fcr\u00fct\u00fcr. Bir i\u015flem veya uygulama, CPU’yu a\u015f\u0131r\u0131 derecede kulland\u0131\u011f\u0131nda, sistem genelinde yava\u015flamalar, donmalar ve tepkisiz bir kullan\u0131c\u0131 deneyimi ya\u015fanabilir. Bu durum, \u00f6zellikle \u015fu senaryolarda sorun te\u015fkil eder:<\/p>\n

* A\u015f\u0131r\u0131 Is\u0131nma ve Donan\u0131m Hasar\u0131:<\/strong> Y\u00fcksek CPU kullan\u0131m\u0131, i\u015flemcinin daha fazla \u0131s\u0131 \u00fcretmesine neden olur. Yetersiz so\u011futma durumunda bu, i\u015flemcinin \u00f6mr\u00fcn\u00fc k\u0131saltabilir veya sistemin kararl\u0131l\u0131\u011f\u0131n\u0131 bozabilir.
\n* Pil \u00d6mr\u00fc:<\/strong> Diz\u00fcst\u00fc bilgisayarlarda y\u00fcksek CPU kullan\u0131m\u0131, pilin \u00e7ok daha h\u0131zl\u0131 t\u00fckenmesine yol a\u00e7ar.
\n* Sistem Tepkiselli\u011fi:<\/strong> Bir uygulama CPU’nun b\u00fcy\u00fck bir k\u0131sm\u0131n\u0131 tekeline ald\u0131\u011f\u0131nda, di\u011fer uygulamalar ve i\u015fletim sistemi \u00e7ekirde\u011fi i\u00e7in yeterli CPU kayna\u011f\u0131 kalmaz, bu da sistemin genel tepkiselli\u011fini d\u00fc\u015f\u00fcr\u00fcr.
\n* Kaynak Payla\u015f\u0131m\u0131:<\/strong> Sunucu ortamlar\u0131nda veya birden fazla sanal makine \u00e7al\u0131\u015ft\u0131ran sistemlerde, CPU kaynaklar\u0131n\u0131n adil ve kontroll\u00fc bir \u015fekilde da\u011f\u0131t\u0131lmas\u0131 kritik \u00f6neme sahiptir.

Bu nedenlerle, CPU kullan\u0131m\u0131n\u0131 y\u00f6netmek ve gerekti\u011finde s\u0131n\u0131rlamak, hem sistem performans\u0131n\u0131 hem de kullan\u0131c\u0131 deneyimini iyile\u015ftirmek i\u00e7in \u00f6nemli bir beceridir.<\/p>\n

CPU Kullan\u0131m\u0131n\u0131 Anlama ve \u0130zleme<\/h3>\n

CPU kullan\u0131m\u0131n\u0131 s\u0131n\u0131rlama ad\u0131mlar\u0131na ge\u00e7meden \u00f6nce, mevcut durumu anlamak ve hangi s\u00fcre\u00e7lerin CPU’yu yo\u011fun kulland\u0131\u011f\u0131n\u0131 belirlemek \u00f6nemlidir. Ubuntu 12.10’da bu ama\u00e7la kullanabilece\u011finiz birka\u00e7 ara\u00e7 bulunmaktad\u0131r.<\/p>\n

Sistem Monit\u00f6r\u00fc<\/h4>\n

Ubuntu’nun varsay\u0131lan olarak sundu\u011fu “Sistem Monit\u00f6r\u00fc” (System Monitor), grafik aray\u00fcz\u00fc sayesinde CPU kullan\u0131m\u0131n\u0131 izlemek i\u00e7in en basit yoldur. Uygulamay\u0131 “Uygulamalar -> Sistem Ara\u00e7lar\u0131 -> Sistem Monit\u00f6r\u00fc” yolunu izleyerek veya Unity Dash’ten aratarak bulabilirsiniz. “S\u00fcre\u00e7ler” sekmesinde, \u00e7al\u0131\u015fan t\u00fcm s\u00fcre\u00e7leri CPU kullan\u0131m\u0131na g\u00f6re s\u0131ralayabilir, b\u00f6ylece hangi uygulaman\u0131n veya servisin i\u015flemcinizi me\u015fgul etti\u011fini kolayca g\u00f6rebilirsiniz.<\/p>\n

top Komutu<\/h4>\n

Terminal tabanl\u0131 bir ara\u00e7 olan top<\/code>, Linux sistemlerinde CPU kullan\u0131m\u0131n\u0131 ve di\u011fer sistem kaynaklar\u0131n\u0131 ger\u00e7ek zamanl\u0131 olarak izlemek i\u00e7in en yayg\u0131n kullan\u0131lan ara\u00e7lardan biridir. Terminali a\u00e7\u0131n (Ctrl+Alt+T<\/code>) ve top<\/code> yaz\u0131p Enter tu\u015funa bas\u0131n.<\/p>\n

S\u00fcre\u00e7ler varsay\u0131lan olarak CPU kullan\u0131m\u0131na g\u00f6re azalan s\u0131rada s\u0131ralan\u0131r. P<\/code> tu\u015funa basarak CPU kullan\u0131m\u0131na g\u00f6re s\u0131ralamay\u0131 garantileyebilirsiniz. k<\/code> tu\u015funa basarak bir s\u00fcreci sonland\u0131rabilir veya r<\/code> tu\u015funa basarak \u00f6nceli\u011fini de\u011fi\u015ftirebilirsiniz (nice de\u011feri).<\/p>\n
htop Komutu<\/h4>\n
htop<\/code>, top<\/code> komutunun daha geli\u015fmi\u015f ve kullan\u0131c\u0131 dostu bir alternatifidir. Renkli aray\u00fcz\u00fc, fare deste\u011fi ve daha kolay s\u00fcre\u00e7 y\u00f6netimi \u00f6zellikleri sunar. Ubuntu 12.10’da htop<\/code> genellikle varsay\u0131lan olarak y\u00fckl\u00fc de\u011fildir, bu y\u00fczden y\u00fcklemeniz gerekebilir:<\/p>\n
sudo apt-get update\nsudo apt-get install htop<\/code><\/pre>\n
Kurulumdan sonra, terminalde htop<\/code> yazarak \u00e7al\u0131\u015ft\u0131rabilirsiniz:<\/p>\n
htop<\/code><\/pre>\n
htop<\/code> ile s\u00fcre\u00e7leri daha kolay bir \u015fekilde \u00f6ld\u00fcrebilir, \u00f6nceliklerini de\u011fi\u015ftirebilir veya filtreleyebilirsiniz.<\/p>\n
Bu ara\u00e7larla hangi s\u00fcre\u00e7lerin CPU’yu yo\u011fun kulland\u0131\u011f\u0131n\u0131 belirledikten sonra, bu s\u00fcre\u00e7lerin CPU kullan\u0131m\u0131n\u0131 s\u0131n\u0131rlamak i\u00e7in \u00e7e\u015fitli y\u00f6ntemleri uygulayabilirsiniz.<\/p>\n

Ancak bu, do\u011frudan bir CPU kullan\u0131m s\u0131n\u0131r\u0131 koymaz; daha ziyade, CPU’nun yo\u011fun oldu\u011fu durumlarda di\u011fer s\u00fcre\u00e7lerin daha \u00f6ncelikli \u00e7al\u0131\u015fmas\u0131n\u0131 sa\u011flar.<\/p>\n
