License Statistics version 5.14 includes the enhancements and fixes detailed below. Most of these improvements were made in response to customer feedback. For more information on how we incorporate customer feedback into our development process, see Customer-driven development. For information about activating your License Statistics license, see Activating a License Statistics license on Windows or Activating a License Statistics license online.

Performance

This release is a result of our hard work to improve License Statistics performance in terms of the number of servers, features and users it is possible to monitor. We achieved these improvements by making changes in data structure and application architecture and by reducing the number of technologies used (which will be continued in future releases for easier maintenance and higher stability). It's also expected that the amount of resources required to run License Statistics will decrease.

Details about the changes introduced in this release are given below. For larger installations, we strongly recommend testing the upgrade procedure before running License Statistics v5.14 in production. If you have any questions or problems, please contact X-Formation Support.

Database Structure

This release significantly modified the database structure. Make sure you follow the License Statistics upgrade procedure for embedded or external database, especially:

  • Create a backup of the License Statistics database in case of any issues with the data migration.
  • Use the new configuration file (xflicstat.cfg) delivered with License Statistics, and adjust it to your needs instead of copying your previous configuration file to the new installation.

SQL Console

Due to significant changes in database structure, we are not able to deliver backward compatibility for custom queries saved in SQL Console. Saved queries may stop working after upgrading to License Statistics v5.14, and they will have to be removed or adjusted to accommodate the new structure.

Configuration file

Renaming of the REPORTSERVER_PORT key to CORE_HTTP_PORT is a breaking change in xflicstat.cfg. License Statistics won't start if this configuration key isn't changed.

Enhancements

License Statistics v5.14 includes the following enhancements.

Separate Java components were merged into single multi-module Java component to reduce resource consumption and simplify maintenance.

Old componentsNew component
  • api.jar
  • core.jar
  • parser.jar
  • querytool.jar
  • report.jar
  • core.jar

LICSTAT-14381

Parser adjustments
LICSTAT-14849

Implemented stricter xsd structure for custom license server:

Attribute nameRequiredPreviously allowed valuesCurrently allowed values
EXPIRESNo

Any string

  • Empty string
  • "permanent"
  • A date in the format:
    YYYY-MM-dd
CHECKOUT_TIMEYes

Any string

YYYY-MM-dd HH:mm

BORROW_EXPIRE_TIMENo

Any string

A date in the format:
YYYY-MM-dd HH:mm

LICSTAT-14400

LICSTAT-14377

LICSTAT-13656

Unified algorithm for parsing Reserved and Borrowed licenses, regardless of license manager type:

  • Borrowed licenses are always included in usage
  • Reserved licenses are never included in usage

Note: Previously, reserved licenses were considered as used for FlexNet License Manager, but were not considered used for LM-X, Custom and DSLS license managers.

LICSTAT-12884Introduced consistent parsing results across all supported license managers compatible with previously gathered data and new database structure.
LICSTAT-4198Dropped support for disabling Feature Versioning for IBM LUM import usage parser in configuration file (DENYLOG_FEATURE_VERSIONING).

LICSTAT-12364Added API endpoints for Database Management operations.
Licensing

LICSTAT-14468

LICSTAT-13279


Improved handling when the License Statistics license's expiration date or limit on monitored users is exceeded.


License exceeded scenarioPrevious handlingCurrent handling
1

Expiration date expires while application is running.

(Not applicable to Perpetual license.)

All license servers are disabled.

User needs to enable them manually after the license is renewed.

Monitoring of all license servers is turned off, but license servers are not disabled (enabled flag is not changed).

After license renewal, license server monitoring is automatically turned on, up to the new license limit. If the maximum number of allowed license servers is fewer than in the previously expired license, then the maximum number of oldest license servers will be turned on.

2Maximum allowed user count from last 14 days was exceeded while monitoring license server.

All data read from license server in current iteration is not saved in database. License server is DISABLED.

User needs to enable them manually after the license is renewed.

All data read from license server in current iteration is not saved in database and email notification is sent (if configured). License server is NOT DISABLED. Data from future iterations will be stored if the license allows for it.

Note: Licensing rules and types of supported licenses are not changed. All existing licenses remain active on the same conditions as before.

Additional enhancements
LICSTAT-14860

Added new email alert for exceeding License Statistics license's user limit.

LICSTAT-14856Changed calculation of users for Current License Usage pie chart on Current Users report to match calculation used for licensing (user-host pairs or usernames only).
LICSTAT-14822Extended SQL Console with ability to make queries returning results in addition to SELECT (for example, SHOW or EXPLAIN queries can now be used).
LICSTAT-14669Importing LDAP User Groups functionality no longer creates empty User Groups.

LICSTAT-14655

LICSTAT-14645

LICSTAT-14644

Links to services that are no longer supported have been removed from email templates, GUI, installer, etc.:

  • https://feedback.x-formation.com
  • https://kb.x-formation.com
  • https://support.x-formation.com

LICSTAT-14649

LICSTAT-14647

EULA in installer has been updated to newest available version.
LICSTAT-14513Dropped ability to "Remove historical data" using the License Server tab. The entire license server can now be removed using the Administration tab, even if there is no configuration for it.
LICSTAT-14490

Introduced information about newest available License Statistics version on page footer.

Note: This feature requires an internet connection; otherwise, no information about new versions will be visible.

LICSTAT-14460Removed functionality of merging two realtime license servers, which was conditionally possible due to an old bug in v4.6.1.
LICSTAT-14342

After making changes to user, host, or license server groups, License Statistics automatically re-generates the reports according to the changes.

Note: It typically takes a few minutes before changes are visible on reports using the edited groups.

LICSTAT-13490Improved label for the Data Removal feature to clarify that the selected day is removed inclusively.
LICSTAT-12940Improved quality of data presented on Usage Per User report. Max columns for group aggregations are calculated based on maximum concurrent usage, not the sum of user maximum usages.
LICSTAT-12390Prevented removing data from current day using the Data Removal feature.
LICSTAT-10995Changed Usage Per User report data aggregation to delay until end of the first day of running License Statistics. All Usage Per User reports are now automatically available starting the day following the day that the first data was gathered.
