This is a document for PGroonga 2.X and 3.X. See PGroonga 1.x document when you're using old PGroonga.
pgroonga.query_log_path parameterpgroonga.query_log_path parameter controls the path of query log.
This parameter is meaningless when you don't use pgroonga_command function. Because query can be executed only via pgroonga_command function.
If you specify relative path, the path is resolved from $PGDATA.
You can disable query log output by specifying none as path.
The default value is none. It means that query log is disabled by default.
In SQL:
SET pgroonga.query_log_path = path;
In postgresql.conf:
pgroonga.query_log_path = path
path is a string value. It means that you need to quote path value such as 'pgroonga.query.log'.
PGroonga outputs query log to path.
Here is an example to output query log to $PGDATA/pgroonga.query.log:
SET pgroonga.query_log_path = 'pgroonga.query.log';
Here is an example to output query log to /var/log/pgroonga.query.log:
SET pgroonga.query_log_path = '/var/log/pgroonga.query.log';
Here is an example to disable query log:
SET pgroonga.query_log_path = 'none';
