Configuring access policies for Performance Insights - Amazon Aurora

Configuring access policies for Performance Insights

To access Performance Insights, a principal must have the appropriate permissions from AWS Identity and Access Management (IAM). You can grant access in the following ways:

  • Attach the AmazonRDSPerformanceInsightsReadOnly managed policy to an IAM user or role.

  • Create a custom IAM policy and attach it to an IAM user or role.

If you specified a customer managed key when you turned on Performance Insights, make sure that users in your account have the kms:Decrypt and kms:GenerateDataKey permissions on the KMS key.

Attaching the AmazonRDSPerformanceInsightsReadOnly policy to an IAM principal

AmazonRDSPerformanceInsightsReadOnly is an AWS-managed policy that grants access to all read-only operations of the Amazon RDS Performance Insights API. Currently, all operations in this API are read-only.

If you attach AmazonRDSPerformanceInsightsReadOnly to an IAM user or role, the recipient can use Performance Insights with other console features.

Creating a custom IAM policy for Performance Insights

For users who don't have the AmazonRDSPerformanceInsightsReadOnly policy, you can grant access to Performance Insights by creating or modifying a user-managed IAM policy. When you attach the policy to an IAM user or role, the recipient can use Performance Insights.

To create a custom policy

  1. Open the IAM console at https://console.aws.amazon.com/iam/.

  2. In the navigation pane, choose Policies.

  3. Choose Create policy.

  4. On the Create Policy page, choose the JSON tab.

  5. Copy and paste the following text, replacing us-east-1 with the name of your AWS Region and 111122223333 with your customer account number.

    { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "rds:DescribeDBInstances", "Resource": "*" }, { "Effect": "Allow", "Action": "rds:DescribeDBClusters", "Resource": "*" }, { "Effect": "Allow", "Action": "pi:DescribeDimensionKeys", "Resource": "arn:aws:pi:us-east-1:111122223333:metrics/rds/*" }, { "Effect": "Allow", "Action": "pi:GetDimensionKeyDetails", "Resource": "arn:aws:pi:us-east-1:111122223333:metrics/rds/*" }, { "Effect": "Allow", "Action": "pi:GetResourceMetadata", "Resource": "arn:aws:pi:us-east-1:111122223333:metrics/rds/*" }, { "Effect": "Allow", "Action": "pi:GetResourceMetrics", "Resource": "arn:aws:pi:us-east-1:111122223333:metrics/rds/*" }, { "Effect": "Allow", "Action": "pi:ListAvailableResourceDimensions", "Resource": "arn:aws:pi:us-east-1:111122223333:metrics/rds/*" }, { "Effect": "Allow", "Action": "pi:ListAvailableResourceMetrics", "Resource": "arn:aws:pi:us-east-1:111122223333:metrics/rds/*" } ] }
  6. Choose Review policy.

  7. Provide a name for the policy and optionally a description, and then choose Create policy.

You can now attach the policy to an IAM user or role. The following procedure assumes that you already have an IAM user available for this purpose.

To attach the policy to an IAM user

  1. Open the IAM console at https://console.aws.amazon.com/iam/.

  2. In the navigation pane, choose Users.

  3. Choose an existing user from the list.

    Important

    To use Performance Insights, make sure that you have access to Amazon RDS in addition to the custom policy. For example, the AmazonRDSPerformanceInsightsReadOnly predefined policy provides read-only access to Amazon RDS. For more information, see Managing access using policies.

  4. On the Summary page, choose Add permissions.

  5. Choose Attach existing policies directly. For Search, type the first few characters of your policy name, as shown following.

    
						Choose a Policy
  6. Choose your policy, and then choose Next: Review.

  7. Choose Add permissions.

Configuring an AWS KMS policy for Performance Insights

Performance Insights uses an AWS KMS key to encrypt sensitive data. When you enable Performance Insights through the API or the console, you can do either of the following:

  • Choose the default AWS managed key.

    Amazon RDS uses the AWS managed key for your new DB instance. Amazon RDS creates an AWS managed key for your AWS account. Your AWS account has a different AWS managed key for Amazon RDS for each AWS Region.

  • Choose a customer managed key.

    If you specify a customer managed key, users in your account that call the Performance Insights API need the kms:Decrypt and kms:GenerateDataKey permissions on the KMS key. You can configure these permissions through IAM policies. However, we recommend that you manage these permissions through your KMS key policy. For more information, see Using key policies in AWS KMS.

The following example shows how to add statements to your KMS key policy. These statements allow access to Performance Insights. Depending on how you use the KMS key, you might want to change some restrictions. Before adding statements to your policy, remove all comments.

{ "Version" : "2012-10-17", "Id" : "your-policy", "Statement" : [ { //This represents a statement that currently exists in your policy. } ...., //Starting here, add new statement to your policy for Performance Insights. //We recommend that you add one new statement for every RDS instance { "Sid" : "Allow viewing RDS Performance Insights", "Effect": "Allow", "Principal": { "AWS": [ //One or more principals allowed to access Performance Insights "arn:aws:iam::444455556666:role/Role1" ] }, "Action": [ "kms:Decrypt", "kms:GenerateDataKey" ], "Resource": "*", "Condition" : { "StringEquals" : { //Restrict access to only RDS APIs (including Performance Insights). //Replace region with your AWS Region. //For example, specify us-west-2. "kms:ViaService" : "rds.region.amazonaws.com" }, "ForAnyValue:StringEquals": { //Restrict access to only data encrypted by Performance Insights. "kms:EncryptionContext:aws:pi:service": "rds", "kms:EncryptionContext:service": "pi", //Restrict access to a specific RDS instance. //The value is a DbiResourceId. "kms:EncryptionContext:aws:rds:db-id": "db-AAAAABBBBBCCCCDDDDDEEEEE" } } }
