Initialize New Relic before including bottle to avoid naming problem when bottle.auth_basic is used.

bottle_with_auth.py

import newrelic.agent
newrelic.agent.initialize('newrelic.ini')

from bottle import route, run, template, app, auth_basic

@route('/public')
def public():
    return 'something something'

@route('/hello/:name')
def index(name):
    return template('<b>Hello {{name}}</b>!', name=name)

def check(u,p):
    return u == "bob" and p == "bob"

@route('/private')
@auth_basic(check)
def private_handler():
    return 'you\'ve found a secret'

run(host='localhost', port=8080, app=newrelic.agent.WSGIApplicationWrapper(app()))
