Technical Tip: How to calculate the percentage of MemAvailable displayed in the Dashboard of FortiAuthenticator

While diagnosing the memory consumption on FortiAuthenticator, the 'get hardware memory' is run in FortiAuthenticator via SSH.

This command gives the below output with a few more parameters:

get hardware memory
### Memory info
MemTotal: 2045340 kB
MemFree: 443636 kB
MemAvailable: 613672 kB

The formula for calculating the percentage is the following:

• ((MemAvailable/MemTotal)*100)= % Of MemAvailable.

For this example:

• ((613672/2045340)*100)=30.00342241.

MemTotal: The amount of RAM, in Kilobytes.
MemAvailable: The amount of memory, available for starting new applications, without swapping.
