Resource classes defined by the microsensor resource manager

Edit online

The microsensor resource manager provides a way to extend the monitoring capabilities of the system by enabling you to create user-defined attributes for monitoring.

Extending the system in this way involves creating a microsensor.

Table 1 describes the classes defined by the microsensor resource manager.

Table 1. Resource classes defined by the microsensor resource manager
Resource class Description
IBM®.Microsensor Each resource of this class represents a microsensor, a dynamically-loaded shared library that provides C-based functions, which the RMC runs to:
  • Obtain control information about the microsensor.
  • Start the monitoring of some user-defined values.
  • Stop the monitoring of some user-defined values.
  • Retrieve the user-defined values.
  • Notify the library that it is no longer needed.

The microsensor is essentially a resource that you add to the microsensor resource class of the microsensor resource manager. The values returned by the functions are dynamic attributes of that resource. Using the event response resource manager commands, you can then create a condition to monitor any of the attributes you have defined. The microsensor resource manager provides a command-line interface for creating, changing, listing, and removing microsensors.

Complete syntax information on the commands is provided in RSCT for AIX®: Technical Reference and RSCT for Multiplatforms: Technical Reference.

For information on listing attribute values or attribute definitions for the resource class (or resource instances of the resource classes) shown in the preceding table, see Listing resource information.
