Statistics Collector

Giriş

Açıklaması şöyle

Here’s an example of how to use the built-in statistics collector to monitor a Postgres database:

• Enable the statistics collector: The statistics collector is disabled by default in Postgres, so you’ll need to enable it in your postgresql.conf file. Set the stats_collector parameter to on, and configure any other relevant settings (such as stats_temp_directory to specify where to store the collected data).
• Collect and analyze metrics: Once the statistics collector is enabled, Postgres will automatically collect metrics and store them in the pg_stat_* system tables. You can query these tables to retrieve information on query performance, database activity, and more. For example, you can use the pg_stat_database view to retrieve information on database-level activity, such as the number of connections, transactions, and queries per second.
