IBM License Metric Tool vs Reprise License Manager (RLM)

IBM License Metric Tool inventories IBM software measured by processor core and measures required licenses in full-capacity and virtualization sub-capacity environments. IBM recommends it for full-capacity licensing and requires it for sub-capacity licensing. It scans infrastructure for installed IBM software and version details that can support version management and security patching. For sub-capacity use, it produces audit reports, tracks license utilization thresholds, and sends email notifications when thresholds approach or exceed their limits. Installation options are License Metric Tool Lite, License Metric Tool with Ansible, and License Metric Tool with BigFix. It integrates with BigFix and provides a REST API for external systems, which must retrieve data through the API rather than directly from the database. The tool is free, with a listed price of free; customers supply hardware and installation services. Linux installations require DB2, included at no charge for use only with the tool. Windows installations require a customer-provided MS SQL Server instance; MS SQL Server Express is supported for environments under 500 endpoints. Sub-capacity audit snapshots must be generated quarterly and kept for at least two years.
