I am using a 512MB Ubuntu 12 VPS. I'd like to get a daily (maximum) memory consumption log, as a reference to add more memory or not.
Is there a tool for this?

I recommend Munin for trending your system statistics.
$ sudo apt-get install munin munin-node
This will install two packages, munin
for aggregating data and munin-node
for collection of data from your system. When munin has been running for a while, you can take a look at the visualized data from it and consider if you need more memory or not.
By default, munin will create HTML-files in the directory /var/cache/munin/www
. Serve these files by a web server and start watching your system trends.
It is also a great tool for trending other statistics.
For detailed statistics, install sysstat and learn how to use sar(1). You know you need more memory when the paging traffic goes high.
