Here is the output from ubuntu top command..

top - 10:54:35 up 50 days, 20:11, 1 user, load average: 0.05, 0.07, 0.08

What does the bold means ?

Cpu(s): 0.0%us, 0.0%sy, 0.0%ni, 98.7%id, 0.0%wa, 0.0%hi, 0.0%si, 1.3%st

I guess sy = system and us = user , id = idle
What does wa , hi , si , st mean ?

Code:

top - 10:54:35 up 50 days, 20:11, 1 user, load average: 0.05, 0.07, 0.08

The field in blue is the current time, the field in red is the uptime (the same you get from the uptime command) that is how long the system is up and running. Regarding the CPU percent times:

Code:

us = user time

sy = system time

ni = nice time (see man nice for details)

id = idle time

wa = I/O waiting time

hi = hardware interrupts time

si = software interrupt time

st = steal time (used by virtual machine/processors)

Hope this helps.
