Well,
Now I get the info with sar comes the problem to understand the results.
Allways I try to see the real used memory in linux I have the same problem,
it seems that it´s using ALL the memory.
with sar -r:
kbmemfree kbmemused %memused kbbuffers kbcached kbswpfree
kbswpused %swpused kbswpcad
12:55:01 408540 3740728 90,15 391560 1191012
4096200 332 0,01 48
my system has 4GB and it looks it has 3,7G in use, but I don´t think it´s
true.
with the free -m command:
free -m
total used free shared buffers
cached
Mem: 4052 3705 346 0 384 1217
-/+ buffers/cache: 2103 1948
Swap: 4000 0 4000
the result is the same, but I have heard that the real free memory is the
in the colum free in the -/+ buffers/cache, is it true?
with vmstat as Manuel suggests:
vmstat -s -S m
4248 m total memory
3907 m used memory
2992 m active memory
738 m inactive memory
341 m free memory
404 m buffer memory
1289 m swap cache
4194 m total swap
0 m used swap
4194 m free swap
....
what is command I get other results
so how many memory are free on my system :-( ?
