How to turn on statistics for your PostgreSQL database? Please read instructions at: http://www.postgresql.org/idocs/index.php?monitoring-stats.html If nothing else, you will have to issue following SQL statement in database that you wish to monitor. Otherwise, you will not get ANY results! set STATS_COMMAND_STRING = true ; set STATS_BLOCK_LEVEL = true ; set STATS_ROW_LEVEL = true ; You could also add following lines in your postgresql.conf: STATS_COMMAND_STRING = true STATS_BLOCK_LEVEL = true STATS_ROW_LEVEL = true This module should be considered "beta". I have no idea what performance penalty for database is to collect statistics and/or pull data to cricket every 5 minutes. You have been warned.
