Using the show-sensors Command at the
OpenBoot PROM
The show-sensors command at OpenBoot PROM displays the readings of all the
temperature sensors on the board. A sample output for typical sensor readings for a
Netra CP2500 is as follows:
Environmental Monitoring Application
Programming
The following sections describe how to use the environmental monitoring functions
in an application program.
For the environmental monitoring application program (envmond) to monitor the
hardware environment, the following conditions must be met:
