2.4.3. Hardware Monitoring
CPU Temp
The SYS temperature is for the overall temperature inside the hardware unit. The CPU temperature
relates specifically to the unit's central processor which can be lower than the overall temperature
due to the method of cooling.
The -verbose option displays the current values plus the configured ranges:
gw-world:/> hwm -a -v
2 sensors available
Poll interval time = 500ms
Name [type][number] = low_limit] current_value [high_limit (unit)

Time to probe sensors: 2.980000e-05 seconds
Each physical attribute listed on the left is given a minimum and maximum range within which it
should operate. When the value returned after polling falls outside this range, NetDefendOS
optionally generates a log message that is sent to the configured log servers.
Setting the Minimum and Maximum Range
The minimum and maximum values shown in the output from the hwm command are set through
the Web Interface by going to System > Hardware Monitoring > Add and selecting the hardware
parameter to monitor. The desired operating range can then be specified.
A sensor is identified in the Web Interface by specifying a unique combination of the following
parameters:
• Type
This is the type of sensor shown in the CLI output above and is presented as a list of choices in
the Web Interface. For example, Temp.
• Sensor
This is the number of the sensor as shown in the CLI output above. For example, the SYS Temp
number is 0.
• Name
This is the Name of the sensor as shown in the CLI output above. For example, SYS Temp.
• Enabled
An individual sensor can be enabled or disabled used this setting. When enabled, an "(x)" is
= 41.500 (C)
Note: The meaning of "(x)"
The "(x)" at the side of each the sensor line, indicates that the sensor is enabled.

Note: Different hardware has different sensors and ranges
Each hardware model may have a different set of sensors and a different operating
range. The above output and its values are for illustration only.
