Physicsal/swap Memory Information

The missing memory you are referring to (I think?) is more than likely being
used by kernel processes.  More detailed memory statistics can be obtain by
using tools such as vmstat and looking at the contents of /proc/meminfo.

 

Thanks,

 

Josh

Hi, 

I would like to ask the forum, (again) about Memory utilization. ...from
which tool i will be able to get information of current max utilization of
Memory.

the output of "top" with "M" is

as you people can see that top utilization of mysql is "93 M" where as the
output of  "free -m" is 

# free -m
              total        used     free  shared    buffers     cached
Mem:      9991       9958        33          0         12       9729
-/+ buffers/cache:        215       9775
Swap:         6142          0       6141


where is remaining  memory ???????????????. 

while i can see the utilization in "GUI" task manger tools .......

any idea. .........

thanks
