Munyaya inotevera tichazotarisa nekukurumidza maitiro atingaite kuongorora disk I / O mashandiro muUbuntu tichishandisa iotop uye iostat maturusi. Semutemo wakazara, vashandisi vanogona kushandisa rairo pamusoro kuziva maitiro ekuuraya ehurongwa (nezvimwe zvinhu) munguva chaiyo uye uone zvingangoita matambudziko. Asi kana isu tikasawana chero nyaya dzekuita zvine chekuita ne kushandiswa kwesimbaKunyanya neCPU uye ndangariro, zvinonakidza kuenderera mberi nekutarisa mimwe minda kuti uone zvipingaidzo.
Mukuraira kuburitsa pamusoro kune minda yatinogona kushandisa kuti tione kana paine epamusoro I / O kuverenga nekunyora mashandiro pane zvigadzirwa zvekuchengetedza uye zvikamu. Kana dhisiki I / O oparesheni iri kumusoro, inogona kunge iri iyo yekukonzeresa kwekuita lag, saka dhisiki I / O nhamba mune ino sisitimu inofanira kuongororwa, uye apa ndipo panogona kutibatsira maturusi e iotop uye iostat.
Iotop uye iostat kuongorora I / O nhamba
Kuti utarise huwandu hweI / O zvakadzama, vashandisi vanogona kushandisa iotop uye iostat mirairo. Iyi mirairo inoshandiswa kuratidza matambudziko ekuita nemidziyo yekuchengetedzakusanganisira ma disks emuno kana iyo network faira system.
Chii chinonzi iotop?
Izvi zvinoshandiswa Izvo zvakafanana nemurairo wepamusoro, asi inoratidza chiitiko chediski munguva chaiyo. Ichi chinoshandiswa chinotarisa kernel I / O ruzivo rwekushandisa uye inoratidza tafura yazvino I / O kushandiswa kuburikidza nemaitiro kana tambo pane ino sisitimu. Iyo zvakare inoratidza iyo bandwidth uye kuverenga uye kunyora I / O nguva yeimwe neimwe maitiro kana tambo.

Uyu murairo unoburitsa mishumo iyo inogona kushandiswa kushandura iyo system yekugadzirisa kuti ive nani kuyananisa iyo yekuisa / yekubuditsa mutoro pakati penyama disks. Iyo iostat yekuraira inogadzira marudzi maviri emishumo; CPU kushandiswa y kushandiswa kwechigadzirwa.
Mune macomprocessor masystem, CPU manhamba anoverengerwa pane ese system sevhareji kune ese ma processor.
Isa iostat
Chishandiso iostat chikamu che sysstat package, iyo inogona kuiswa kubva kune yepamutemo repository. Isu tinongoda kuvhura terminal (Ctrl + Alt + T) uye nekuita rairo mairi:
