Thread: Count actual transaction per minute?
| pgsql-general@postgresql.org Can anyone tell me how to measure _actual_ transactions per minute on a PostgreSQL server. I am not talking about using pgbench, as I am not interested in determining what is possible, but rather the actual count of queries / transactions being sent to the server.

| Thanks very much! I put that query into a script that puts the initial result into a variable, sleeps for a minute, queries again into a second variable and subtracts the difference. Works fine.
