Yuav ua li cas tag nrho CPU siv suav rau Linux server saib?

  1. Kev siv CPU yog xam siv 'sab saum toj' hais kom ua. Kev siv CPU = 100 - idle time.
  2. idle nqi = 93.1. Kev siv CPU = (100 - 93.1) = 6.9%
  3. Yog lub server yog an AWS, CPU siv tau suav nrog cov formula:

Ntxiv mus, CPU siv cov txheej txheem suav li cas?

Siv tau Kev siv CPU rau kev ua haujlwm yog xam raws li feem pua ntawm cov zuam tau dhau los ntawm CPU nyob rau hauv hom neeg siv lossis hom ntsiav rau tag nrho cov zuam dhau los. Yog hais tias nws yog multithreaded txheej txheem , lwm cov cores ntawm processor kuj siv summing tag nrho kev siv feem pua yuav ntau tshaj 100.

Tsis tas li ntawd, kuv yuav txwv CPU siv ntawm Linux li cas? Kev txwv cov txheej txheem CPU siv zoo, cpulimit, thiab cgroups

  1. Siv cov lus txib zoo kom txo qis txoj haujlwm tseem ceeb.
  2. Siv cov lus txib cpulimit kom rov ncua cov txheej txheem kom nws tsis pub dhau ib qho kev txwv.
  3. Siv Linux cov pab pawg tswj hwm ua ke, ib lub tswv yim uas qhia tus neeg teem sijhawm kom txwv cov peev txheej muaj rau cov txheej txheem.

Ib yam li ntawd, nws tau nug, cov txheej txheem twg siv ntau dua CPU Linux?

14 Cov cuab yeej hais kom ua kab txhawm rau txheeb xyuas CPU siv hauv Linux

  1. 1) Sab saum toj. Cov lus txib saum toj kawg nkaus qhia txog lub sijhawm saib ntawm cov ntaub ntawv ntsig txog kev ua haujlwm ntawm tag nrho cov txheej txheem khiav hauv qhov system.
  2. 2) Iostat.
  3. 3) Vwm.
  4. 4) Kev tiv thaiv.
  5. 5) Sib.
  6. 6) CoreFreq.
