An HP-UX DMI 2.0 Example Code
The Example Component
The Example Component
The component used in HP's System Example, like all components, is
created from two types of elements in the Component Interface: the
component's MIF file and the various instrumentation files.
The systemExample.mif, like all components, contains the Component
ID Group. This static group contains the six attributes required to
identify a component. They are Manufacturer, Product, Version, Serial
Number, Installation, and Verify.
The example component MIF also contains two dynamic data groups:
the scalar System Group and the tabular Processor Time Group. The
System Group contains the attributes Total Physical Memory and Total
Processors. The Processor Time Group contains the attributes
Processor ID, Sleep Time, Run Time, Zombie Time, and Idle Time. The
attributes within these two groups are accessed dynamically and
require component instrumentation.
Figure A-3
Example Component
Component instrumentation for the dynamic data in this example is
handled in the ci_systemExample.h file. Instrumentation provided by
the developer is identified as following between headers and footers like
those illustrated below. The corresponding ci_systemExample.c file does
not need to be modified.
