Transaction Metrics

This page documents Prometheus metrics related to active database transactions in Yellowbrick, offering insight into transactional concurrency and long-running transaction behavior.

Purpose

These metrics are useful for:

• Tracking the number of currently open transactions in the system
• Detecting long-running transactions that could block vacuum, DDL, or create risk of transaction ID wraparound
• Supporting transaction-level diagnostics during query or session analysis
• Informing tuning of idle timeout or transaction isolation strategies
