Обсуждение: Capturing just slow queries
Hi,
log_min_duration_statement captures all statements including DMLs that have exceeded the threshold. Is there a way in PG 12 to capture just select statements excluding all DMLs and DDLs? In my environment, it's acceptable for DMLs and DDLs to cross the threshold and we are more interested in capturing poor performing select statements.
Thanks.

Thank you for the information. That's a comprehensive list of monitoring solutions. I'll take a look.
