The show environment command display reports the current environmental status of the system.
The report displays the date and time of the query, the refresh times, the overall system status, and
any parameters that are out of the normal values. No parameters are displayed if the system status is
normal. The example that follows shows the display for a system in which all monitored parameters
are within Normal range.

Environmental status as of Sat 10-31-1992 16:42:48
Data is 0 second(s) old, refresh in 60 second(s)
All Environmental Measurements are within specifications
If the environmental status is not normal, the system reports the worst-case status level in the last
line of the display, instead of the status summary that is shown in the last line of the preceding
example. For example, if the fan array is not operating properly, the system displays the following
warning message:
WARNING: Fan has reached CRITICAL level
The show environment last command retrieves and displays the NVRAM log of the reason for the
last shutdown and the environmental status at that time. If no status is available, it displays the reason
as unknown.

The show environment table command displays the temperature and voltage thresholds for each
monitored status level, which are the same as those listed in Tables 1-7 and 1-8. The current
measured values are displayed with the unit of measure noted, (V) or (C), and each is listed below a
column heading that indicates its current status level. Measurements that fall within the Normal
range are displayed in the Normal column of the table, while measurements that have reached a
critical level are shifted to the Critical column, and so on.
