I don't believe this information is logged. The labeling engine lives in
"gt-render", a module of GeoTools. The sources are here:
https://github.com/geotools/geotools/tree/master/modules/library/render
I think that the paintLabels method in the LabelCacheImpl class would be a
good place to start looking to implement this feature, but it may be the
case that candidate labels are already discarded before that method gets
called.
