Recommendations reference for the Splunk App for AWS
The Splunk App for AWS presents selected recommendations to you about your AWS environment on the Topology dashboard.
If any recommendations are available for you to review, the recommendations icon in the top right corner of your Topology dashboard displays a number in a small orange circle.
Click the icon to open your recommendations list and review each one.
Prerequisites
Python for Scientific Computing
The app's ability to evaluate your environment and provide recommendations depends on the Python for Scientific Computing app, available on Splunkbase. Install the version appropriate for your environment on all Splunk search heads running the Splunk App for AWS, or contact a Splunk software admin to perform this installation for you.
- Python for Scientific Computing for Linux 64-bit
- Python for Scientific Computing for Windows 64-bit
- Python for Scientific Computing for Linux 32-bit
- Python for Scientific Computing for Mac
CLI tools
To use the commands provided by the app to take action on the recommendations, you need the CLI tools. See http://docs.aws.amazon.com/AWSEC2/latest/CommandLineReference/ec2-cli-get-set-up.html for more information. You can also use the AWS Management Console to perform these actions in the UI instead of using the commands.
IAM permissions
To perform the suggested actions on your AWS EC2 resources, use an account with the following permissions.
ec2:StartInstances ec2:StopInstances ec2:ModifyInstanceAttribute ec2:DeleteSecurityGroup
Recommendations
Delete security groups
The Splunk App for AWS polls your security groups to check if any are not assigned to any EC2 instances. Unused security groups can be deleted to make it easier to organize and manage your environment. For more information about deleting a security group using the CLI or in the AWS management console, see http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html#deleting-security-group.
Upgrade or downgrade instances
The Splunk App for AWS evaluates your instance usage to determine if any instances are either over- or under-utilized. The app will identify the instances that should be resized to a larger instance type to avoid performance problems or downtime. The app will also identify instances that are underutilized so that you can save cost by resizing those to smaller instance types.
For more information about modifying an instance type using the AWS Management Console, see http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-resize.html. For more information about the modify-instance-attribute
CLI command, see http://docs.aws.amazon.com/cli/latest/reference/ec2/modify-instance-attribute.html.
