Is it normal behavior Swap : 0k total, 0k used, 0k free, 3751268k cached ?

L1 Bithead

Hello.

 

Since last week in my monitoring there is an alert of 0% available in swap memory in my 5220 firewall.

 

When I check it by cli the firewall with the command show system resources it shows me the following:

 

KiB Swap: 0 total, 0 free, 0 used. 27097872 avail Mem

 

Swap 0 0 UNKNOWN

 

I would like to know if this is normal behavior, I have already reviewed two KB of the topic but it is not very clear to me if it is normal to have a total, free and used in 0.

 

In the note it only indicates 0 in used but does not say anything about the others.

 

These are the notes I found:

Your recommendations or experiences with this swap behavior would help me a lot.

Regards.

Has this firewall been set up stood up recently? if so, this is normal and it hasn't needed to create swap yet

keep an eye on your used/available 'mem' first. If that is running empty and still no swap appears, there could be an issue
