# TIER Beacon Opt-out
# Completely uncomment the following ENV line to prevent the containers from sending analytics information to Internet2.
# With the default/release configuration, it will only send product (Shibb/Grouper/COmanage) and version (3.3.1-17040, etc) 
#   once daily between midnight and 4am.  There is no configuration or private information collected or sent.  
# This data helps with the scalaing and funding of TIER.  Please do not disable it if you find the TIER tools useful.
# To keep it commented, keep multiple comments on the following line (to prevent other scripts from processing it).
