View instance monitoring information

The Instance Monitoring page in the AnalyticDB for PostgreSQL console shows real-time metrics for your instance's health, connections, and storage—within any time window up to seven days. Use it to:

Spot abnormal storage growth or connection spikes before they affect your workloads.
Correlate performance degradation with a specific time window.
Confirm that an instance is healthy after a configuration change.

Prerequisites

Before you begin, make sure you have:

An AnalyticDB for PostgreSQL instance
Access to the AnalyticDB for PostgreSQL console

View instance monitoring data

Log on to the AnalyticDB for PostgreSQL console.
