Database Hosts

The Hosts tab provides a host-level view of your monitored database instances, showing key performance and resource utilization metrics.

Hosts Table

Column	Description
Database Host	Instance hostname or endpoint
Queries/s	Average queries per second
Total Duration	Cumulative query execution time
Avg Duration	Mean query execution time
Max Duration	Longest single query execution
Rows/s	Rows processed per second
Avg CPU Utilization	Average CPU usage percentage
Max CPU Utilization	Peak CPU usage percentage

Filters

The left-hand panel provides:

• Database Type — Filter by engine (PostgreSQL, MySQL). Each type is shown with its logo icon.
• Version — Filter by database version.
• Database Identifier — Search by DB instance identifier.

Click to Drill Down

Click a host row to open a detail drawer with:

• Overview metrics — CPU utilization, active connections, queries per second, and replication lag over time.
• Databases table — Lists each database on the host with its size, active connections, commits, rollbacks, and conflict count.
• Replication metrics — Write lag, flush lag, replay lag, and replication slot delay (when applicable).

Use Cases

• Capacity planning — Identify hosts approaching CPU or connection limits.
• Performance debugging — Correlate host-level resource spikes with query duration increases.
• Fleet management — Compare performance across database instances to find outliers.
