Deploy Datasentinel via AWS Marketplace with Metering

https://aws.amazon.com/marketplace/pp/B08L436C4Q

AWS Marketplace Metering Service

Datasentinel manages PostgreSQL instance registration and monitoring within your Amazon subscription.

Costs are based on the hourly monitoring count of instances.

For further information on pricing, please refer to the AWS Marketplace.

This deployment type does not require purchasing individual licenses.

To make use of individual licenses on AWS, just deploy an EC2 instance, install Datasentinel, and apply the license.

EC2 requirements

The EC2 instance containing the Datasentinel server must meet the following requirements.

Requirement	Details
IAM role permission	An IAM role with the aws-marketplace:MeterUsage permission must be associated with the EC2 instance This permission allows the role to contact the Metering Service API and record usage. A user with rights to define and assign roles can create the role in either of the following ways: 1. Create the role on the Configure Instance Details panel of the wizard 2. Manually create the role To get the aws-marketplace:MeterUsage permission, attach the AWS managed policy AWSMarketplaceMeteringFullAccess to the role. If a role with the required permissions is not associated with the EC2 instance, Datasentinel reports issues with metering service availability. For more information, see: Subscribing, Launching, and Managing Products on AWS
Access to the metadata URL	The EC2 instance must have HTTP connectivity to 169.254.169.254, which is a local IP address accessible only from within Amazon instances. To validate that the EC2 instance can access the metadata service, execute the following command: curl http://169.254.169.254/latest/meta-data/ The command returns a list of available metadata items. For more information: Retrieving Instance Metadata
Access to the metering service	The EC2 instance must be able to reach the AWS Metering Service (MeterUsage API). The URL is: https://metering.marketplace.{region}.amazonws.com/ The region is where your EC2 instance is running For example: https://metering.marketplace.us-east-1.amazonaws.com To be able to launch Datasentinel, you must have an Internet gateway configured. The Metering Service has an endpoint on the public Internet. To access the Metering Service, your Virtual Private Cloud must be configured to allow an outbound HTTPS connection to the public Internet. For more information, see https://docs.aws.amazon.com/vpc/latest/userguide/vpc-network-acls.html To validate that the EC2 instance can connect to the Metering Service, execute the following command: curl https://metering.marketplace.{region}.amazonws.com/ Replace {region} with the region where your EC2 instance is running. You should receive healthy as a response from the server.

How to connect to Datasentinel?¶

• How to Access Your EC2 Instance

Connect to the Linux AMI via SSH using the ec2-user and authenticating with a public key.

• To connect to Datasentinel application

Launch a web browser and enter the host name (Public DNS) or IP address of your new Datasentinel instance as the URL.

To log in, enter datasentinel

The default password is the AWS instance ID.

Troubleshooting

Encountering this error while connecting to the GUI signifies a communication issue between Datasentinel and the AWS Marketplace.

There exists a variety of potential reasons

• The IAM Role does not exist or does not have the right rights

• Metadata is not accessible (Version v1 and v2)

// To inspect the metadata service, 
// establish an SSH connection to the server using 'ec2-user' credentials
curl --max-time 1 http://169.254.169.254/latest/meta-data/product-codes

How to add your PostgreSQL instances?

After the installation is finalized, the only remaining task is to configure the instances for monitoring.

You'll have the option to choose between:

• Agent-based mode

Install an agent on each server locally and configure it to establish communication with the platform. This is particularly suitable when you have direct control over your PostgreSQL instances.

🕶️pageAgent

• Agentless mode

Set up connections directly through the user-friendly graphical interface. This approach is optimal for AWS managed instances such as RDS and Aurora. Additionally, you can automate connection additions via the API.
