Feature Availability
Certain D-Link hardware models allow the administrator to use the CLI to query the current value
of various hardware operational parameters such as the current temperature inside the firewall.
This feature is referred to as Hardware Monitoring.
Configuring and performing hardware monitoring can be done either through the CLI or
through the Web Interface.
Enabling Hardware Monitoring
The System > Device > Hardware Monitoring section of the Web Interface provides the
administrator with the following settings for enabling hardware monitoring when it is available:
Enable Sensors
Enable/disable all hardware monitoring functionality.
Default: Disabled
Poll Interval
Polling interval for the Hardware Monitor which is the delay in milliseconds between readings of
hardware monitor values.
Minimum value: 100
Maximum value: 10000
Default: 500
Using the hwm CLI Command
To get a list of the current values from all available sensors, the following command can be used:
gw-world:/> hwm -all
This can be abbreviated to:
gw-world:/> hwm -a
Some typical output from this command for two temperature sensors is shown below:
gw-world:/> hwm -a
Note: Hardware monitoring is not available on all models
The hardware monitoring feature is not available on the DFL-260E and DFL-860E.
