Statement Monitoring

Installation of the pg_stat_statements module and creation of the extension in at least one database is required for statement tracking. Basic steps follow below. For more information on how to install this, refer to the relevant PostgreSQL documentation for your version.

1. In postgresql.conf, set these sample properties. The pg_stat_statments module allows more advanced configuration, but these are the minimum required.
   shared_preload_libraries = 'pg_stat_statements'
   pg_stat_statements.max = 10000
   pg_stat_statements.track = all
   
   More info on properties: https://www.postgresql.org/docs/current/static/pgstatstatements.html
2. Restart server
3. In PSQL, pgAdmin, or another client program, execute this statement when connected to any database (postgres is fine): "CREATE EXTENSION pg_stat_statements;" The pg_stat_statements view should appear in DB's public schema. If the public schema does not exist, create this first.
4. When configuring the Foglight for PostgreSQL agent properties, make sure to enable statement tracking and provide the database name where the extension was created.
