App Engine has an API for getting datastore statistics programmatically:

DatastoreService datastore = DatastoreServiceFactory.getDatastoreService();
Entity globalStat = datastore.prepare(new Query("__Stat_Total__")).asSingleEntity();
Long totalBytes = (Long) globalStat.getProperty("bytes");
Long totalEntities = (Long) globalStat.getProperty("count")

See the documentation: https://cloud.google.com/appengine/docs/java/datastore/stats

You can get entities of a kind using __Stat_Kind__
