# Notebook Telemetry
#
# Elastic relies on anonymous usage statistics to continuously improve. This
# script allows us to see which notebooks are most used, which in turn helps us
# redirect our efforts to the areas that matter most to our users.
#
# What data is collected?
#
# This script configures your elasticsearch client to send a custom user agent
# string with requests made to Elastic Cloud. The new user agent contains
# the name of the notebook and the platform you are running it on. Here is an
# example user agent:
#
#     searchlabs-py/00-quick-start (Colab)
#
# No other data is collected by this script.
