[GENERAL] Linux TOP

2009-10-21 Thread Waldomiro
Hi, I have one of my database server that I run the "top" command: top - 16:16:30 up 42 days, 13:23, 4 users, load average: 3.13, 3.52, 3.36 Tasks: 624 total, 1 running, 623 sleeping, 0 stopped, 0 zombie Cpu(s): 1.4%us, 1.1%sy, 0.0%ni, 84.4%id, 12.9%wa, 0.0%hi, 0.2%si, 0.0%st Mem: 16432240k
