Query Logs


The Funnelback query logs provide an important record of the queries that have been used on the search service. The query logs are vital for purposes such as generating reports on how the search service is being used.

Log Locations

The Funnelback query log is located at:

data_root/collection_name/live/log/queries.log (e.g. /opt/funnelback/data/shakespeare/live/log/queries.log)

This log file is updated for each query.

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


The archived file is named according to the current date:

Example: /opt/funnelback/data/shakespeare/archive/queries.log.20040715

Log Formats

Query log files have the following format: one line in the logfile per query processed and each line contains fields separated by commas. Some example lines from a query log:

Mon Sep  8 14:51:13 2008,100.200.300.400,gdp graph,g"0",,1,10,2x,0,1,28,info
Mon Sep  8 14:51:26 2008,,public holidays,g"0",,1,10,2x,21677,425628,7,
Mon Sep  8 14:51:51 2008,,tax,,,1,10,2x,129974,0,4,

The comma-separated fields are described in the following table:
