FitterHappier
=============

FitterHappier is a Rails plug-in that provides actions for monitoring site and/or database availability. FitterHappier's monitoring controller disables unnecessary Rails features, like sessions, layouts, and logging, for lightning-fast monitoring URIs.

FitterHappier provides three monitoring URIs

% curl localhost:3000/fitter_happier
FitterHappier Site Check Passed

% curl localhost:3000/fitter_happier/site_check
