Article ID: KB8394 KB Last Updated: 22 May 2019Version: 6.0
Summary:
Below you'll find information about the Memory Utilization calculation for the bar displayed on the WebUI:
Solution:

When the firewall starts up, there is some memory pre-assigned to certain processes on the box. The percentage of memory utilization that is noticed in the Memory bar in the WebUI is calculated based on the amount allocated and the amount left, not on the total memory on the box.

For example, an SSG-5 has 128MB of total memory. But when you do a "get mem" it shows:

ns-> get mem
Memory: allocated 34687824, left 19223616, frag 187

The memory bar on the WebUI is basically calculated as a percentage of allocated / (allocated + left).

In this case it is percentage of 34687824 / (34687824 + 19223616).
=> which is (34687824 / 53911440) x 100 % = 64.34
