Count Palo Alto Memory Usage

L2 Linker

Hello All,

I want to ask about memory on PA-850 and PA-3410.

i use the calculation "Free Memory/Total Memory = xxx %" and the rest i assume is the used memory

 

 

but when i see the memory utilization on PA-3410 its only have 210MB for free memory. 

so when i use the calculation, the free memory only 1% from the total memory, it has a large number on used and buffer.

(i was checked on several PA-3410 it show the same picture like a attach below).

I was following the Kb : How to calculate the actual used memory - Knowledge Base - Palo Alto Networks

but i think it have a little different with my palo alto.

 

is this categorized as a high memory?

i still confuse about buffer/cache is this categorize as a free/used memory.

 

PA-850

free is memory that is not being used at all while buffer/cache is memory that was once used and is kept in a ready state in case a process asks for the memory again. Both are not actively used but the buffer/cache has some preloaded data for quick access, this buffer data can be freed if another process needs more memory for a task

 

the high memory indicator would be the diff between total and used
