Click logs

The Funnelback click logs record collection search results and best bets that users have clicked on and provides information on popular results.

Usage

Set click_tracking=true in a collection’s collection.cfg file to enable click logging.

Log locations

Live Funnelback logs are located at:

data_root/collection_name/live/log/*.log (e.g. /opt/funnelback/data/shakespeare/live/log/clicks-localhost.log)

This log file is updated for each click. Note that older versions of Funnelback store clicks in queries.log and later versions use clicks.log.

When the collection is updated, these files are then archived by moving them to the directory:

data_root/collection_name/live/archive

The archived file is named according to the current date and hostname e.g. /opt/funnelback/data/collection/archive/clicks-localhost.20190827_022830.log.gz.

Log format

Click logs have the following format: one line in the log file per click processed and each line contains fields separated by commas. Some example lines from a clicks.log:
