Additional information for creating STM rules
Manufacturers assign unique OIDs to their SNMP-instrumented products. In addition, systems supply information
about themselves using variables described in files called MIBs . These values are enumerated using an
industry-standard structure. MIBs are provided by vendors for their systems and must be registered with HP
SIM to be accessible and usable from STM . HP preregisters all HP MIBs and many third-party MIBs. You
can register the remaining MIBs using the MIB compiler, if you have the related systems on your network.
See “Registering a MIB” for information about registering MIBs. If you examine a MIB, you will find modules,
or groups of variables. Some variables have multiple values. Each of these values has an OID as well. You
can use these OIDs to determine which system you have and its current behavior by querying these OIDs.
Things you should know about DMI identification
DMI identification is based on how a system responds to a DMI request. Systems supply information about
themselves as defined in files called MIFs. MIFs are vendor-specific. Simply having a MIF file on a target
system does not guarantee DMI identification. MIFs cannot be registered the way MIBs are registered in HP
SIM. If you examine a MIF (for example, the generic Win32sl.MIF), you will find groups of attributes. The
values returned in response to requests for MIF attributes can be used to determine which system you have
and its current behavior.
For example, the following extract is part of the Win32sl.MIF. Notice the group named Component ID ,
followed by several attributes that identify one aspect of a DMI system (such as Manufacturer, Product,
Version, and Serial Number). Other MIFs have different groups and specify other aspects of a system. The
information in the MIFs is the information supplied to STM when you create a rule. STM can request a value
from a specific target for a specific attribute.
NOTE: DMI identification is only supported on Windows and HP-UX-based CMS installations. In addition,
only like operating systems can be identified. For example, a Windows-based CMS can identify a
Windows-based DMI, while HP-UX-based Central Management Server can only identify HP-UX-based DMI
systems.
