3% in last 5 seconds
Average CPU usage in the last 5 seconds. (After the firewall boots, the firewall
calculates and records the average CPU usage at the interval of 5 seconds.)
3% in last 1 minute
Average CPU usage in the last minute. (After the firewall boots, the firewall
calculates and records the average CPU usage at the interval of 1 minute.)

Table 7 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:Buffers + Mem:Cached,
which indicates the physical memory available for applications.
Swap Swap memory.
