Temperature 37 Centigrade
CPU utilization 0 percent
Interrupt utilization 0 percent
Heap utilization 16 percent
Buffer utilization 43 percent
DRAM 64 Mbytes
Internet Processor II Version 1, Foundry IBM, Part number 9
Start time 1999-01-24 16:24:42 UTC
Uptime 2 hours, 21 minutes, 28 seconds
Meaning The command output displays the temperature of the air passing by the FEB, in degrees
Centigrade. It displays the total percentage of CPU, interrupt, heap space, and buffer
space being used by the FEB processor, including the total DRAM available to the FEB
