MySQL Need unix/linux command
Hi,

When i ran the command as sar in linux box. i got a output like as below

Code:
[spt@scrbgcddkcph431 tools]$ sar
Linux 2.6.18-274.3.1.el5 (scrbgcddkcph431)      06/29/2012

12:00:01 AM       CPU     %user     %nice   %system   %iowait    %steal     %idle
12:10:01 AM       all           8.78       0.00      26.11       3.80         0.00        61.30
12:20:01 AM       all           3.09       0.00      5.12         1.13         0.00        90.65
