Connections

The Connections tab breaks down current database connections and tracks utilization over time.

What it shows​

  • Connection counts by state — active, idle, idle in transaction, and other states.
  • Connections by user — which database users have the most connections.
  • Connections by application_name — which applications are consuming connection slots.
  • max_connections utilization — current count as a percentage of the configured limit.

Auto-refresh​

The tab refreshes while active. A manual Refresh button is also available.

Connection history​

If performance samples are available, a connection history chart shows active, idle, and idle-in-transaction counts over time.

High connection utilization feeds into the max_connections recommendation on the Tuning tab. When the app sees high utilization combined with many idle sessions, it recommends connection pooling instead of blindly raising the connection limit.
