Turning Performance Insights on and off for Aurora

Focus mode

Turning Performance Insights on and off for Aurora - Amazon Aurora

You can turn on Performance Insights for your DB cluster when you create it. If needed, you can turn it off later by modifying your DB cluster from the console. Turning Performance Insights on and off doesn't cause downtime, a reboot, or a failover.

Note

Performance Schema is an optional performance tool used by Aurora MySQL. If you turn Performance Schema on or off, you need to reboot. If you turn Performance Insights on or off, however, you don't need to reboot. For more information, see Overview of the Performance Schema for Performance Insights on Aurora MySQL.

If you use Performance Insights with Aurora global databases, turn on Performance Insights individually for the databases in each AWS Region. For details, see Monitoring an Amazon Aurora global database with Amazon RDS Performance Insights.

The Performance Insights agent consumes limited CPU and memory on the DB host. When the DB load is high, the agent limits the performance impact by collecting data less frequently.

Console

In the console, you can turn Performance Insights on or off when you create a DB cluster. Enabling Performance Insights allows you to manage Performance Insights settings and options for your DB cluster. Cluster level settings apply to all DB instances the cluster.

Turning Performance Insights on or off when creating a DB cluster

After creating a new DB cluster, Amazon RDS enables Performance Insights by default. To turn off Performance Insights for your DB cluster, choose the option Database Insights – Standard and deselect the option Enable Performance Insights.

To create a DB cluster, follow the instructions for your DB engine in Creating an Amazon Aurora DB cluster.

The following screenshot shows the Performance Insights section.

Turn on Performance Insights during DB cluster creation with console.

If you choose Enable Performance Insights, you have the following options:

Retention (for the Standard mode of Database Insights only) – The amount of time to retain Performance Insights data. The retention setting in the free tier is Default (7 days). To retain your performance data for longer, specify 1–24 months. For more information about retention periods, see Pricing and data retention for Performance Insights.
AWS KMS key – Specify your AWS KMS key. Performance Insights encrypts all potentially sensitive data using your KMS key. Data is encrypted in flight and at rest. For more information, see Changing an AWS KMS policy for Performance Insights.

Turning Performance Insights on or off when modifying a DB cluster

In the console, you can modify a DB cluster to manage Performance Insights.

To manage Performance Insights for a DB cluster using the console

Sign in to the AWS Management Console and open the Amazon RDS console at https://console.aws.amazon.com/rds/.
Choose Databases.
Choose a DB cluster, and choose Modify.
To turn on Performance Insights, select Enable Performance Insights. To turn off Performance Insights for your DB cluster, choose the option Database Insights – Standard and deselect the option Enable Performance Insights.

If you choose Enable Performance Insights, you have the following options:
- Retention (for the Standard mode of Database Insights only) – The amount of time to retain Performance Insights data. The retention setting in the free tier is Default (7 days). To retain your performance data for longer, specify 1–24 months. For more information about retention periods, see Pricing and data retention for Performance Insights.
- AWS KMS key – Specify your KMS key. Performance Insights encrypts all potentially sensitive data using your KMS key. Data is encrypted in flight and at rest. For more information, see Encrypting Amazon Aurora resources.
Choose Continue.
For Scheduling of Modifications, choose Apply immediately. If you choose Apply during the next scheduled maintenance window, your instance ignores this setting and turns on Performance Insights immediately.
Choose Modify instance.

AWS CLI

When you use the create-db-instance AWS CLI command, turn on Performance Insights by specifying --enable-performance-insights and set --database-insights-mode to either advanced or standard. To turn off Performance Insights, specify --no-enable-performance-insights and set database-insights-mode to standard.

You can also specify these values using the following AWS CLI commands:

To manage Performance Insights for a DB cluster using the AWS CLI

Call the modify-db-cluster AWS CLI command and supply the following values:
- --db-cluster-identifier – The name of the DB instance in your DB cluster.
- --enable-performance-insights to turn on or --no-enable-performance-insights to turn off
- database-insights-mode – The mode of Database Insights for the DB cluster. To turn off Performance Insights, set this value to standard.
The following example turns on Performance Insights for sample-db-cluster.

For Linux, macOS, or Unix:
```
aws rds modify-db-cluster \
	--database-insights-mode standard \
    --db-cluster-identifier sample-db-instance \
    --enable-performance-insights
```
For Windows:
```
aws rds modify-db-cluster ^
	--database-insights-mode standard ^
    --db-cluster-identifier sample-db-instance ^
    --enable-performance-insights
```

When you turn on Performance Insights in the CLI, you can optionally specify the number of days to retain Performance Insights data with the --performance-insights-retention-period option. You can specify 7, month * 31 (where month is a number from 1–23), or 731. For example, if you want to retain your performance data for 3 months, specify 93, which is 3 * 31. The default is 7 days. For more information about retention periods, see Pricing and data retention for Performance Insights.

The following example turns on Performance Insights for sample-db-cluster and specifies that Performance Insights data is retained for 93 days (3 months).

For Linux, macOS, or Unix:


aws rds modify-db-cluster \
	--database-insights-mode standard \
    --db-cluster-identifier sample-db-instance \
    --enable-performance-insights \
    --performance-insights-retention-period 93

For Windows:


aws rds modify-db-cluster ^
	--database-insights-mode standard ^
    --db-cluster-identifier sample-db-instance ^
    --enable-performance-insights ^
    --performance-insights-retention-period 93

If you specify a retention period such as 94 days, which isn't a valid value, RDS issues an error.


An error occurred (InvalidParameterValue) when calling the CreateDBInstance operation: 
Invalid Performance Insights retention period. Valid values are: [7, 31, 62, 93, 124, 155, 186, 217, 
248, 279, 310, 341, 372, 403, 434, 465, 496, 527, 558, 589, 620, 651, 682, 713, 731]

Note

You can only toggle Performance Insights for an instance in a DB cluster where Performance Insights is not managed at the cluster level.

RDS API

When you create a new DB instance in your DB cluster using the CreateDBInstance operation Amazon RDS API operation, turn on Performance Insights by setting EnablePerformanceInsights to True. To turn off Performance Insights, set EnablePerformanceInsights to False and set DatabaseInsightsMode to standard.

You can also specify the EnablePerformanceInsights value using the following API operations:

When you turn on Performance Insights, you can optionally specify the amount of time, in days, to retain Performance Insights data with the PerformanceInsightsRetentionPeriod parameter. You can specify 7, month * 31 (where month is a number from 1–23), or 731. For example, if you want to retain your performance data for 3 months, specify 93, which is 3 * 31. The default is 7 days. For more information about retention periods, see Pricing and data retention for Performance Insights.
