You can use the Tablestore console to view the monitoring data of an instance, a data table, a secondary index, or a search index. For example, you can view the queries per second (QPS), number of rows, traffic statistics, and capacity units (CUs) of an instance. You can also view the average access latency and QPS of a data table, secondary index, or search index. In addition, you can view the metering data of a search index, such as the storage volume, number of reserved read CUs, and number of rows.
Prerequisites
If you view the monitoring data of Tablestore as a RAM user, make sure that the following prerequisites are met:
The
AliyunOTSFullAccessorAliyunOTSReadOnlyAccesspolicy is attached to the RAM user. The AliyunOTSFullAccess policy grants full access to Tablestore to the RAM user. The AliyunOTSReadOnlyAccess policy grants read-only access to Tablestore to the RAM user. For more information, see Grant permissions to a RAM user.The
AliyunCloudMonitorFullAccessorAliyunCloudMonitorReadOnlyAccesspolicy is attached to the RAM user. The AliyunCloudMonitorFullAccess policy grants full access to CloudMonitor to the RAM user. The AliyunCloudMonitorReadOnlyAccess policy grants read-only access to CloudMonitor to the RAM user. For more information, see Grant permissions to a RAM user.
You can also create custom policies to manage permissions in a fine-grained manner. For more information, see Create custom policies.
Usage notes
The Tablestore metrics available vary based on the resource types. For more information, see the Metrics section of the "Overview" topic.
The collection of monitoring data statistics may be delayed.

View monitoring data of data tables or indexes
You can view monitoring data such as the average access latency, QPS, number of rows, and traffic statistics of data tables, secondary indexes, or search indexes in the Tablestore console.
The operation types vary based on the types of the resources whose monitoring data you want to view.
Go to the Instance Management page.
Log on to the Tablestore console.
In the top navigation bar, select a region and a resource group.
On the Overview page, click the name of the instance that you want to manage or click Manage Instance in the Actions column of the instance that you want to manage.

Specify a time range.
You can select a preset time range or specify a custom time range. The time range cannot exceed 30 days.
Specify the monitoring data that you want to view.
By default, Overview is selected for Metric Group. You can specify a value for Operation Type to view the monitoring data of all metric groups regarding the specified operation type.
NoteSearch indexes do not support the Table Size metric group.
If you want to view the monitoring data of all operation types based on a specific metric group, set Metric Group to the required metric group. For example, you can set Metric Group to Average Latency. The following figure shows the monitoring data of all operation types based on the average access latency.
