Обсуждение: How to mesure transaction rate in Postgres

Hello,

I've been asked for the transaction rate we have on an installed Postgres server. Where and how can I get this information. I could not find anything in the documentation. I have root access to the system.

Thank you for your Help.

connect to database, and issue this command:
begin; create table not_previously_existsing(id int4); select xmin from pg_class where relname = 'not_previously_existsing'; rollback;

returned value is id of the transaction that created the table.
repeat this command every so often (mrtg does that every 5 minutes), and you can see how it grows.

Or just SELECT xact_commit + xact_rollback FROM pg_stat_database;
