free memory = buff/cache + available memory?
It's under my impression that free memory is just by looking at available memory. I am wondering it is not correct. seems like free memory calculation = available memory + buff/cache.
What is the formula to calculate free memory?
total used free shared buff/cache available
Mem: 15G 4.9G 596M 8.6G 10G 914M <-- available is 914M and buff/cache is 10G
Swap: 8.0G 978M 7.0G
Please shed some light on this issue.
