Hardware Sensor Attributes (Sun N1 System Manager 1.2 Administration Guide)

Sun N1 System Manager 1.2 Administration Guide

Hardware Sensor Attributes

For x86 servers, the management server software obtains the list of hardware sensor attributes to monitor through IPMI from the service processor of the server. For servers running the SPARC architecture, the ALOM interface is used. The list of hardware sensor attributes can vary from server to server, and between firmware versions. A sample listing for some servers and firmware versions is provided in this section. The attributes depend on the server type and on the number of CPUs that the server has.

Note –

Hardware disk failure and memory failure are not monitored in this version of the N1 System Manager.

The following example lists sensor names and descriptions for a Sun Fire V40z server with firmware version 2.1.0.16.
