Hardware Health Monitoring

The hardware health of discovered servers is monitored. Sensors provided in the hardware are used to monitor temperature, voltage, and fan speed. For more information about associated hardware, see the Sun N1 System Manager Connection Information in Sun N1 System Manager 1.1 Site Preparation Guide.

Sensor data is retrieved from the service processor for SPARC devices through the Advanced Lights Out Manager (ALOM) interface. Sensor data is retrieved from IPMI for x64 servers.

General management interface data for Sun Fire V20z and Sun Fire V40z machines is obtained through the command line. General management interface data for Sun Fire x4100 and Sun Fire x4200 servers is obtained through IPMI. Data can be retrieved dynamically from the command line.

The following characteristics of server hardware can be monitored:

• CPU temperature

• Ambient temperature

• Fan speed in revolutions per minute

• Voltages

• LEDs

A detailed list of these sensors is provided in Hardware Sensor Attributes.

You can view filtered hardware health monitoring information for all servers by using the show server command:

N1-ok> show server health health

See show server in Sun N1 System Manager 1.1 Command Line Reference Manual for details of possible values of the health filters.
