Hi folks,

i looked at the output of vzmemcheck and realized something
wired, the allocated Memory, shown in 'free' is much lower
than shown in 'vzmemcheck'. I will look into the code if i
find time for that. Here is a sample:

so far...

vzmemcheck doesn't show free.
Can you point to the numbers in the picture which make you worry?

Thanks,

Okay, maybe its a misunderstanding, i worry about the following:

veid LowMem LowMem RAM MemSwap MemSwap Alloc Alloc Alloc
util commit util util commit util commit limit

3 3.35 34.01 150.99 150.99 1248.72 579.61 290.00 1057.99

so, VPS 3 has a committed allocation of 290MB (65535 Pages) and a
allocation limit of 1057MB (262140 Pages). If i look at the allocation
utilization it shows me 579MB, but according to 'free' the machine has
390MB RAM used, so am i wrong with my supposition that 'Alloc util' is
the total RAM used? Or is 'RAM util' the determining factor for the
_real_ memory consumption?

Thanks

AFAIK,
Alloc refers to virtual address space,
RAM to physical memory.
Also you should remember that host system is not listed here, but
consumes some memory as well (actually can be seen in
/proc/user_beancounters)
