Enabling and disabling Performance Insights - Amazon Aurora

Enabling and disabling Performance Insights

To use Performance Insights, enable it on your DB instance. If needed, you can disable it later. Enabling and disabling Performance Insights 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.

If you use Performance Insights together with Aurora Global Database, enable Performance Insights individually for the DB instances 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.

In the console, you can enable or disable Performance Insights when you create or modify a new DB instance.

Enabling or disabling Performance Insights when creating an instance

When you create a new DB instance, enable Performance Insights by choosing Enable Performance Insights in the Performance Insights section. Or choose Disable Performance Insights.

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

The following screenshot shows the Performance Insights section.

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

  • Retention – The amount of time to retain Performance Insights data. Choose either 7 days (the default) or 2 years.

  • 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 Configuring an AWS KMS policy for Performance Insights.

Enabling or disabling Performance Insights when modifying an instance

In the console, you can modify a DB instance to enable or disable Performance Insights using the console.

To enable or disable Performance Insights for a DB instance using the console

  1. Sign in to the AWS Management Console and open the Amazon RDS console at https://console.aws.amazon.com/rds/.

  2. Choose Databases.

  3. Choose a DB instance, and choose Modify.

  4. In the Performance Insights section, choose either Enable Performance Insights or Disable Performance Insights.

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

    • Retention – The amount of time to retain Performance Insights data. Choose either 7 days (the default) or 2 years. If you chose Long Term Retention (2 years) when you enable Performance Insights, All displays 2 years of data. If you chose Default (7 days) instead, All displays only the past week.

    • 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.

  5. Choose Continue.

  6. For Scheduling of Modifications, choose Apply immediately. If you choose Apply during the next scheduled maintenance window, your instance ignores this setting and enables Performance Insights immediately.

  7. Choose Modify instance.

When you use the create-db-instance AWS CLI command, enable Performance Insights by specifying --enable-performance-insights. Or disable Performance Insights by specifying --no-enable-performance-insights.

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

The following procedure describes how to enable or disable Performance Insights for a DB instance using the AWS CLI.

To enable or disable Performance Insights for a DB instance using the AWS CLI

  • Call the modify-db-instance AWS CLI command and supply the following values:

    • --db-instance-identifier – The name of the DB instance.

    • --enable-performance-insights to enable or --no-enable-performance-insights to disable

    The following example enables Performance Insights for sample-db-instance.

    For Linux, macOS, or Unix:

    aws rds modify-db-instance \ --db-instance-identifier sample-db-instance \ --enable-performance-insights

    For Windows:

    aws rds modify-db-instance ^ --db-instance-identifier sample-db-instance ^ --enable-performance-insights

When you enable Performance Insights, you can optionally specify the amount of time, in days, to retain Performance Insights data with the --performance-insights-retention-period option. Valid values are 7 (the default) or 731 (2 years).

The following example enables Performance Insights for sample-db-instance and specifies that Performance Insights data is retained for two years.

For Linux, macOS, or Unix:

aws rds modify-db-instance \ --db-instance-identifier sample-db-instance \ --enable-performance-insights \ --performance-insights-retention-period 731

For Windows:

aws rds modify-db-instance ^ --db-instance-identifier sample-db-instance ^ --enable-performance-insights ^ --performance-insights-retention-period 731

When you create a new DB instance using the CreateDBInstance operation Amazon RDS API operation, enable Performance Insights by setting EnablePerformanceInsights to True. To disable Performance Insights, set EnablePerformanceInsights to False.

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

When you enable Performance Insights, you can optionally specify the amount of time, in days, to retain Performance Insights data with the PerformanceInsightsRetentionPeriod parameter. Valid values are 7 (the default) or 731 (2 years).
