envmond - Environmental Monitoring daemon
Environmental Monitoring provides a means of detecting
system threshold conditions, that if exceeded, could
result in a loss of data or damage to the system itself.
Using the envmond daemon, thresholds levels can be checked
and corrective action can ensue before any damage occurs.
The envmond daemon performs the following: Queries the
system for exceeded threshold levels. Broadcasts a message
to users warning of high threshold conditions or fan
and power supply failure, and suggests corrective action.
Sends a message to users when a high temperature condition
has been resolved. Notifies all users that an orderly
shutdown is to be initiated if recovery is not possible.
To enable Environmental Monitoring, the envmond daemon
must be started during the system boot. Before starting
Environmental Monitoring, a system check is performed. If
the system hardware does not support Environmental Monitoring,
the envmond daemon is not started.
You can customize, start, and stop the envmond daemon
using the envconfig utility. For more information, see
the envconfig reference page.
Some recent computer systems feature multiple sensors for
environmental monitoring. On those systems, the hwmgr
utility is used to set and read individual sensor
attribute values ( including thresholds) and to specify
actions to undertake when these thresholds are reached.
