Schedule Regular Scans
- Configure Scan Frequency: Set up the ILMT agent to perform regular scans. A best practice is to run scans at least once a week to ensure up-to-date software usage reporting.
- Validate Data Collection: Monitor the ILMT console to ensure data from all endpoints is collected successfully.
- Automate Data Collection: Automate the scanning process to minimize manual intervention and reduce the risk of missing data collection deadlines.
Reporting and Managing Compliance
One of ILMT’s primary functions is to provide accurate and timely reporting of software usage to facilitate compliance.
Generating Reports
- Sub-Capacity Reports: ILMT generates reports detailing the consumption of IBM products under sub-capacity licensing. These reports must be regularly reviewed and retained for audit purposes.
- Custom Reports: Use the ILMT reporting capabilities to create custom reports that provide insights into specific products or usage trends.
- Audit-Ready Compliance: IBM requires that sub-capacity reports are generated and retained for at least two years to demonstrate compliance during audits.
Identifying Non-Compliance
- License Overages: If ILMT reports show that the usage exceeds the purchased licenses, it’s crucial to immediately purchase additional licenses or reduce usage.
- Resolving Issues: Utilize ILMT’s alerts to detect anomalies or errors in the data collection process. For example, if an endpoint has not reported data in a while, it may require troubleshooting.
- Mitigation Strategies: Develop mitigation strategies for non-compliance, such as reallocating resources or purchasing additional licenses.
Maintaining ILMT
Regular maintenance is essential to keep ILMT functioning effectively and ensure the collected data remains accurate.
Updates and Patches
- Apply Regular Updates: IBM periodically releases updates to ILMT, which include bug fixes, new features, and security patches. Ensure that your ILMT installation is always up to date.
