Review Comment:
The 7th item indicates the size of cached memory which may not be suitable.
```shell
MemTotalInGB="$(cat /proc/meminfo | grep 'MemTotal' | awk '{print int($2 /
1024 / 1024)}')"
MemAvailableInGB="$(cat /proc/meminfo | grep 'MemAvailable' | awk '{print
int($2 / 1024 / 1024)}')"
```
These metrics may be useful.
MemTotalInGB = total
MemAvailableInGB = free + buffers/cache
