using Boost Log to generate application time distribution?

Question

I have an Eigen-based C++ application where I'm interested in generating the time distributions for the different steps in a way one could generate a time distribution performance plot. This will help quickly finding the current bottlenecks e.g. compiling using MKL as backend etc.

How can I use Boost Log for this purpose? is there built in support in Boost Log to show the elapsed time from the last logging statement for a specific level?

Answer 1

OK I found it, the Boost Log library (I'm using the latest 1.54) supports predefined and custom attributes and this is how the functionality is offered. The predefined attribute Stop Watch (timer) "provides high resolution of the time estimation and can even be used as a simple in-place performance profiling tool."
