bootchart
The auditing is performed by a tool that runs in your initramfs, or early in your boot sequence, and records system statistics as your computer boots.
Tarballs of this data are left in /var/log/bootchart; from these either PNG or SVG will be generated if pybootchartgui is installed.

There is a bug in bootchart (at least with Mint Cinnamon 18.1 (Serena)): Bootchart never stops logging. This causes the /udev filesystem to grow (since Bootchart stores saved logs in /udev/.bootchart). Since udev is a memory resident filesystem; it starts using more memory. My 16 GBs PC run out of memory in 4 hours and the OOM (Out Of Memory) manager started killing applications. At the end I got a kernel panic; since I was using 15 GBs for buffes/cache. If you experience something similar, just check the disk usage of /udev.
Decent tool - you can get details from bootchart.org. Note, bootchart checks some standard ubuntu windows managers to trigger stop logging. Since Mint uses mdm this means it NEVER STOPS. This will kill your memory eventually. Add mdm to the list of programs in /etc/init.d/bootchart in order to fix it.
great tool, but lacks documentation, for example: How to disable it? Where is the GUI of pybootchartgui? Etc etc..
