The Lucidity Cost Saving Assessment uses AWS Systems Manager Run Command to securely collect configuration and storage information from EC2 instances. This is a standard AWS mechanism used by thousands of customers — no agents, no SSH keys, and no access to customer data.
What these commands do
They gather only infrastructure metadata needed for storage and optimization analysis, such as:
Attached disks and partitions
Storage pools / volume groups
Available vs. used capacity
Operating system version
Why SSM is used
100% read-only and automated
No manual login
Secure and fully auditable via CloudTrail
Respects customers’ access boundaries and security policies
Purpose of commands
Purpose | Example Actions |
|---|---|
Identify disks & filesystems | List block devices, physical or virtual disk, mount points, drive letters |
Check available storage | View free space & total size |
Check advanced storage setups | Identify Btrfs/ZFS/LVM or Windows Pool where applicable |
OS identification | Retrieve Linux or Windows OS version |
Uses native PowerShell cmdlets like Get-PhysicalDisk & Get-Partition for Windows and df, lsblk, are used for Linux — all standard OS utilities
Compliance & Transparency
All SSM actions are logged in AWS CloudTrail
SSM Run Command history is visible in your AWS console
No customer data is read, stored, or transmitted
Short-lived access only for the duration of Assessment. Once a role is deleted all access is removed.
The tool uses secure, read-only AWS native methods to collect storage configuration details — not application or user data. This ensures a smooth and secure optimization assessment without disrupting workloads or requiring privileged access.
