Requirements for FlexNet Manager Suite Sub-Cap

FlexNet Manager Suite 2022 R1 (On-Premises)

The full set of requirements for using FlexNet Manager Suite to calculate sub-capacity license calculations for IBM PVU or IBM VPC licenses divides into two groups: the legal conditions that IBM writes into the amended license agreement; and the mechanical requirements imposed by the product. An understanding of these requirements helps to guide you through the processes described in the subsequent pages.

IBM requirements for sub-capacity licensing

Using FlexNet Manager Suite data (derived from the 2015 release or later) to determine an IBM PVU or VPC license position on IBM software may be acceptable by IBM for sub-capacity reporting in place of IBM License Metric Tool (ILMT), Tivoli Asset Discovery for Distributed (TAD4D), IBM Software Usage Analysis (SUA), or IBM BigFix Inventory. This requires all of the following:

• You must be using FlexNet Manager Suite 2015 or later. (This documentation is for 2022 R1.) This product must be installed, configured and maintained correctly.
• You must have licensed (and use) the FlexNet Manager for Datacenters product.
• Inventory must be collected by the FlexNet inventory agent, which must be installed directly on the device(s) running (or that may run) the software that is linked to an IBM PVU or VPC license. The method of installation of the FlexNet inventory agent does not matter, and installation may be achieved (for example) by any of:
  • Adoption, using separate inventory rules targeting the servers in question to trigger the adoption
  • Deploying the FlexNet inventory agent independently, using your own preferred infrastructure tools
  • Including the FlexNet inventory agent in the base image used to clone virtual machines that may run relevant software
  • Installing the FlexNet inventory agent manually.

• You must increase the frequency of hardware inventory scanning on the target device so that it is performed every 30 minutes. The IBM reporting and archiving settings section of the Inventory Settings page contains the settings for the required increased frequency of hardware scanning.
• On the same frequency, you must check the virtual hosts (VMware vCenter, Oracle VM Manager and Hyper-V servers) for any changes affecting VMs running the software attached to an IBM sub-capacity license.

Product prerequisites for higher frequency processing of IBM sub-capacity licenses

The following technical conditions must be satisfied before you can use this facility:

• Permission: You have licensed the FlexNet Manager for Datacenters product.
• Inventory: Inventory must be collected by the FlexNet inventory agent locally installed on the devices that are (or may be) running software attached to IBM sub-capacity licenses. While you may use targets to trigger adoption of these devices, you may alternatively use any deployment method. For example, you might install the FlexNet inventory agent in your base image used to clone virtual machines.
• License with consumption: You have at least one IBM PVU or IBM VPC license linked to one or more applications that have installations shown in inventory. Since both IBM PVU and IBM VPC licenses are points-based licenses, you must be using the appropriate points rule: this may be one of the standard points rule sets downloaded with the Application Recognition Library, or (if you have negotiated a custom points rule with IBM), you may have a locally-customized points rule (remembering that where Flexera points rules and local points rules overlap, the local rule has priority).
• Reconciled: You have run a Reconcile since inventory was collected, triggering consumption from the above license. The initial gathering of this inventory and calculation of consumption is used to trigger operation of two specialized and normally hidden targets, described next.
• Targets: FlexNet Manager Suite automatically maintains two relevant targets:
  1. Servers running VMware vCenter and Oracle VM Manager (OVM Manager) — these servers (which may also manage clusters) do not expose their VM management to a locally-installed FlexNet inventory agent. For FlexNet Manager Suite to gather data about the VMs under management, this target must be used for inventory gathering by the inventory beacon remotely accessing the management API (this is called 'direct' inventory gathering, since it does not involve any form of the FlexNet inventory agent).
     Tip: Note that the list of these servers is not visible on the Discovery and Inventory Rules page in the web interface, but functions as a hidden target called Known vCenter or OVM Manager servers in the web interface: its use is controlled through a check box titled Collect inventory from VMware vCenter or Oracle VM Manager servers .
     When the Collect inventory from VMware vCenter or Oracle VM Manager servers check box is selected and the default Known vCenter or OVM Manager servers option is selected in the accompanying drop down list, this automated inventory, used to track the movement of virtual machines, is collected on the same frequency as the inventory of the devices running software attached to an IBM sub-capacity license. This target is populated from the discovered device records, so you must ensure discovery of all relevant servers before the target becomes effective. This hidden target automatically updates to include all discovered vCenter or OVM Manager servers, so that newly-installed sub-capacity-related software can be identified in dynamic environments. Alternatively, you may prefer to create your own custom target(s) that identify only those vCenter or OVM Manager servers known to manage VMs running PVU-related software. This enables you manage scanning, limiting it to only managers of inventory devices relevant to IBM sub-capacity licenses; but it also means that if you later deploy additional managers of VMs that should consume from IBM sub-capacity licenses, you must remember to update your targets to avoid creating an audit risk. (For details about creating targets, see the Creating a Target page in the online help.)
     Remember: Remote inventory gathering from virtual hosts requires that you have saved credentials for these servers in the Password Manager on the inventory beacon accessing the servers. (For details about using the Password Manager, see the Password Management Page page in online help.)
     Tip: IBM also allows that, in addition to VMware and Oracle hosts, several other virtual hosts are acceptable for sub-capacity consumption of IBM PVU licenses. However, these hosts do not require the same direct inventory gathering as the VMware vCenter and Oracle VM Manager servers described above. For example:

     • For Hyper-V hosts, the FlexNet inventory agent locally installed on the host server is able to collect all required information about the deployment of VMs. These hosts are automatically included in the target described below, rather than in the target for direct inventory.
     • For partitioned technologies other than Solaris zones, the FlexNet inventory agent gathers sufficient information from the partition, and separate inventory of the host is not required for IBM sub-capacity calculations (although, of course, you may have the FlexNet inventory agent installed on the host to gather regular software and hardware inventory for that device). As you expect, partitions reporting inventory from the FlexNet inventory agent are also included in the automatic target described below.
     • For Solaris zones, it is critical that the FlexNet inventory agent is installed in the global zone as well as in the non-global zones. Only the global zone inventory reports the required number of processors and cores. If inventory from the global zone is missing, the non-global zones on this host do not contribute to the peak consumption calculations (because of the missing core and processor counts), and this represents an audit risk. When the FlexNet inventory agent is correctly installed in all zones, they are all automatically included in the following target.
  2. Computers running software attached to an IBM sub-capacity license (a target called All devices consuming IBM PVU points, which, despite the name, actually collects all devices consuming IBM sub-capacity licenses, both IBM PVU and IBM VPC where applicable) — these computers require the FlexNet inventory agent installed locally (called 'adoption' when you are defining targets, although you may use other methods of deployment). In production, use of this target is required for compliance with IBM's conditions.
     Tip: The special target All devices consuming IBM PVU points is not visible on the Discovery and Inventory Rules page in the web interface. It is available only in the IBM reporting and archiving settings section of the Inventory Settings page, and only when you have first selected Enable frequent hardware scanning for IBM sub-capacity license calculations.
  These two automated targets rely on data already reaching the central application server. To 'seed' these automated processes, you need rules that execute the initial discovery actions on the target devices. Naturally, these rules require additional targets manually prepared:
  • A target for discovery of the servers running VMware vCenter and Oracle VM Manager (do not allow adoption on these devices).
  • A target for discovery and inventory of devices running software attached to an IBM PVU or IBM VPC license. In the case of (only) this target, you may also choose to configure the target for 'adoption' of devices (that is, automatically installing the FlexNet inventory agent locally on the target devices); or you may prefer alternative deployment methods.
  • Hyper-V hosts may be included in the previous target; or you might prefer a separate target for managing these virtual hosts. You could allow adoption of these devices; or use third-party methods to install the full FlexNet inventory agent locally on the Hyper-V host.
  During development or testing, you may need extra targets in special circumstances, such as:
  • Your inventory management team is ahead of your licensing team, and wants sign-off that they are collecting all required inventory, even though IBM sub-capacity license set up is not yet complete. The system cannot use consumption against the missing IBM sub-capacity licenses as a data source to update the list of computers that need special, more frequent hardware scans. If the inventory team knows of computers that have relevant software installed, which in due course will be linked to an IBM sub-capacity license, you can create a temporary target for those computers so that frequent hardware scans start as quickly as possible, for compliance with IBM's requirements.
  • Your licensing team is ahead of your inventory team. The IBM PVU and IBM VPC licenses all exist, and a complete list of the computers to manage with frequent hardware scans could be generated; but permission for increased hardware checks on some of the target devices has not yet arrived. In this case, do not use the built-in target All devices consuming IBM PVU points, but instead manage your own targets that include only computers where hardware inventory gathering is permitted. This could be a politically useful temporary measure; but you should not allow it to continue, as it does not meet IBM's conditions. You can identify computers that are consuming from IBM PVU licenses, but not yet subject to high-frequency scanning, in the IBM PVU Out-Of-Date Inventory report (see below) – there is no equivalent report for VPC licenses.
• Scheduled: While the schedule for inventory gathering by the installed FlexNet inventory agents is determined when you enable high-frequency scanning, you can separately configure your schedule for reporting periods (which govern how often you need to archive reports for IBM), for the switch-over date for reporting, and the length of time to retain historical data.
• Enabled: When all else is ready, you must enable high-frequency inventory mode for IBM sub-capacity licenses.
