Description
Slot 1 CPU 0 CPU usage
CPU 0 usage information for the interface module in slot 1.
0% in last 5 seconds
Average CPU usage in the last 5 seconds. (After the device boots, the device
calculates and records the average CPU usage at intervals of 5 seconds.)
0% in last 1 minute
Average CPU usage in the last minute. (After the device boots, the device
calculates and records the average CPU usage at intervals of 1 minute.)
0% in last 5 minutes
Average CPU usage in the last 5 minutes. (After the device boots, the device
calculates and records the average CPU usage at intervals of 5 minutes.)

Table5-3 Output description
Field
Description
Slot
Slot number of the interface module.
Mem
Memory usage information.
Total
Total size of the physical memory space that can be allocated.
The memory space is virtually divided into two parts. Part 1 is used for
kernel codes, kernel management, and ISSU functions. Part 2 can be
allocated and used for such tasks as running service modules and
storing files. The size of part 2 equals the total size minus the size of part
1.
Used
Used physical memory.
Free
Free physical memory.
Shared
Physical memory shared by processes.
Buffers
Physical memory used for buffers.
Cached
Physical memory used for caches.
FreeRatio
Free memory ratio.
-/+ Buffers/Cache
-/+ Buffers/Cache:used = Mem:Used – Mem:Buffers – Mem:Cached,
which indicates the physical memory used by applications.
-/+ Buffers/Cache:free = Mem:Free + Mem:B Mem:Cached,
which indicates the physical memory available for applications.
Swap
Swap memory.
