TargetMetrics.targets_configured
Number of targets/aspects configured during this build. Does not include targets/aspects that were configured on prior builds on this server and were cached. See BuildGraphMetrics below if you need that.
TargetMetrics.targets_configured_not_including_aspects
Number of configured targets analyzed during this build. Does not include aspects. Used mainly to allow consumers of targets_configured, which used to not include aspects, to normalize across the Blaze release that switched targets_configured to include aspects.
TargetMetrics.targets_loaded
DEPRECATED No longer populated. It never measured what it was supposed to (targets loaded): it counted targets that were analyzed even if the underlying package had not changed. TODO(janakr): rename and remove.
