Hi!
I'm using B.11.11.
vmstat
Memory:
avm: 717500
free: 625727
Multiply it by 4096 to get size in bytes. So, is it correct:
625727 * 4096 / 1024 / 1024 = 2444MB ??
This value is real "free memory"?
Please, could someone give me a help?
Thanks

hi,
try glance -m
e.g.
Total VM : 1.21gb Sys Mem : 1.27gb User Mem: 455.9mb Phys Mem: 8.00gb
Active VM: 888.5mb Buf Cache: 409.6mb Free Mem: 5.88gb
$ vmstat -n
VM
memory page faults
avm free re at pi po fr de sr in sy cs

vmstat output is not straight-forward. The value you have computed for free memory is ok.
hope this helps!

Re: vmstat (correct interpretation)
cfeitosa,
I always use glance for MEM usage and reporting. It gives you "real" information as opposed to top or vmstat or even swapinfo, they can/are very misleading as to the output of the information.
Take care,
Adam
