The command output displays the temperature of air passing by the SFM, in degrees
Centigrade. It displays the SFM CPU usage, including the total percentage used by the
SFM processor and the percentage used for interrupts.
The command output also displays the percentage of memory usage, including the total
DRAM available to the SFM processor, in megabytes (MB), and the percentage of heap
space (dynamic memory) being used by the SFM processor. Heap utilization greater than
80 percent can indicate a software problem (memory leak). The output shows the
percentage of buffer space being used by the SFM processor for buffering internal
messages.
If the SFM summary command output indicates that there is a problem, you can display
more detailed SFM status information with the following command:
