Linux öndürijiligine gözegçilik etmek üçin Sysstat Utilities-iň 20 peýdaly buýrugy (mpstat, pidstat, iostat we sar)
Geçen makalamyzda sysstat paketini gurmak we kämilleşdirmek we paket bilen gelýän kömekçi enjamlar barada gysgaça düşünmek hakda öwrendik.
- Sysstat - Linux üçin öndürijilik we ulanyş işjeňligine gözegçilik guraly
Bu gün, meseleleri kesgitlemäge kömek edip biljek mpstat, pidstat, iostat we sar enjamlarynyň käbir gyzykly amaly mysallary bilen işlemekçi. Bu kömekçi enjamlary ulanmak üçin dürli mümkinçiliklerimiz bar, dürli görnüşli iş üçin dürli opsiýalar bilen buýruklary el bilen otlap bilersiňiz ýa-da talaplaryňyza görä ýöriteleşdirilen skriptleri döredip bilersiňiz. Sysadminsiň elmydama ýalta bolandygyny bilýärsiňiz we elmydama iň az tagallalar bilen işleri etmegiň aňsat ýoluny tapmaga synanyşýarsyňyz.

13. Aşakda sar çagyrmak üçin esasy buýruk bar. Häzirki katalogyňyzda “sarfile” atly bir faýl döreder. “-U” opsiýalary CPU jikme-jiklikleri üçin bolup, 2 sekunt aralygynda 5 hasabat ýygnaýar.

14. aboveokardaky mysalda sar bilen interaktiw ýüz tutduk. Şeýle hem, skriptleri/usr/local/lib/sa1 we/usr/local/lib/sa2 ulanyp (gurnama wagtynda prefiks hökmünde/usr/ýerli ulanan bolsaňyz), kron arkaly interaktiw däl ýüz tutmak mümkinçiligimiz bar.
- /usr/local/lib/sa1 gündelik ikilik log faýlyny döredýän kron meýilnamalaşdyrmak üçin ulanyp boljak gabyk skriptidir.
- /usr/local/lib/sa2 gabyk skriptidir, ikilik log faýlyny adam okalýan görnüşe üýtgeder.
Bu interaktiw däl etmek üçin aşakdaky Kron ýazgylaryny ulanyň:
