A tool to find out how memory consumption is evolving
The vps utility has been modified to keep a snapshot of the memory used by processes.
It records the virtual size and the resident size. It does this for the host server
and for every containers independently.

It has two operation mode:

!Collection

It keeps in a file with a record for every program. If a program has many instances, it sums up
the memory usage of all instances and save the totals. You use this after a restart
of all services, for example.

!Compare

It collects the memory usages and compare them with the previous statistics stored
in a file. It then presents every processes where the virtual size or resident size has increased.

We created this tool after our test server went havoc because the network-manager service had
filled the swap. So now we have the tool to figure out which service is growing.
