You can run Apache in single process mode and strace that (provided that
Apache isn't needed for anything else at the time):
strace -o outputfile -f apache2 -X
You should see mod_tile (a) trying to open the tile on disk (grep for
the filename) and if unsuccessful (b) trying to contact renderd (grep
for the renderd socket name).
