How do we enable the display of costs within appengine appstats? The documentation from here says this:
Displaying cost
AppStats can keep track of RPC cost as well as time. If your application is fast enough but more expensive than you expect, look for operations that cost more than you expect. To turn on cost tracking, set appstats_CALC_RPC_COSTS = True in your appengine_config.py file.
I've tried to do this, with the the code below:
# appengine_config.py
from google.appengine.ext import vendor
vendor.add('lib')
def webapp_add_wsgi_middleware(app):
from google.appengine.ext.appstats import recording
appstats_CALC_RPC_COSTS = True
app = recording.appstats_wsgi_middleware(app)
return app
However, visiting myapp.appspot.com/_ah/stats still displays zero values for both the cost and cost% columns.
Visiting the quota page on the app engine cloud console also doesn't display any helpful information, no stats, no nothing. I can however see the historical costs when I click on View usage history, however, these are the costs from days previous.
