AnalyticDB:View node monitoring information

Prerequisites

Before you begin, ensure that you have:

• An AnalyticDB for PostgreSQL instance

• Access to the AnalyticDB for PostgreSQL console

View node monitoring information

1. Log on to the AnalyticDB for PostgreSQL console.

2. In the upper-left corner of the console, select a region.

3. Find the instance you want to monitor and click its instance ID.

4. In the left-side navigation pane, choose Monitoring and Alerts > Node Monitoring. The Node Monitoring page has the following sections:

   • Node Status — Shows the overall health of the instance, including Coordinator Node Health Status, Compute Node Connection Health Status, Coordinator Node Connection Health Status, and Compute Node Storage Status. Check this section first to identify unhealthy nodes before drilling into specific metrics.

   • Coordinator Nodes tab — Shows performance metrics for coordinator nodes: CPU Utilization (%), I/O Usage (%), and Memory Usage (%). High CPU or memory utilization on coordinator nodes can slow query planning and distribution across compute nodes.

   • Compute Nodes tab — Shows performance metrics for compute nodes: CPU Utilization (%), I/O Usage (%), Memory Usage (%), Storage Used (MB), and Storage Usage (%). Monitor storage metrics to anticipate capacity issues before they affect query execution.

   Available metrics vary by instance resource type. For the full list of metrics per resource type, see Performance parameters.

5. (Optional) Select a time range to view metrics for a specific period.

   The interval between the start time and end time cannot exceed seven days.
