Monitor the columnar resources of a PolarDB-X instance - PolarDB

This topic describes how to monitor the columnar resources in the PolarDB-X console.

Note

You can only monitor the columnar resources of PolarDB-X Enterprise Edition instances.

Procedure

Log on to the PolarDB-X console.
In the top navigation bar, select the region where the instance is deployed.
On the Instances page, click the PolarDB-X 2.0 tab.
Find the instance that you want to manage and click the instance ID.
In the left-side navigation pane, choose Monitoring and Alerting > Columnar Resource Monitoring. Then, click the Cluster or Node tab to view the monitoring metrics for the columnar resources.
Note
- The Cluster tab displays the average metric values of all columnar nodes.
- The Node tab displays the metric values for a single columnar node.

Metric	Description
CPU Utilization	The columnar node's CPU utilization. Unit: %.
Memory Usage	The columnar node's memory utilization. Unit: %.
IMCIs	The total number of in-memory column indexes (IMCIs) in the instance.
IMCI Partitions	The total number of IMCI partitions in the instance.
Synchronization Throughput	The throughput of committed data during the synchronization process to the instance. Unit: bytes/s.
Synchronized Rows	The number of committed rows during the synchronization process to the instance.
Synchronization Delay	The delay between the successful synchronization of binlog events and the current time. Unit: milliseconds.
Backend Compaction Tasks	The number of real-time background compaction tasks currently being executed by the columnar storage system.
Binlog Event Synchronization Throughput	The number of binlog events consumed by the columnar storage system.
Binlog Reception Delay	The delay between the consumption of binlog events and the current time. Unit: milliseconds.
