 How do I check my VPS Memory Resource Usage?
Solution You can use the command free -m to check the memory usage.

-bash-2.05b# free -m
total used free shared buffers cached
Mem: 1024 186 837 0 0 0
-/+ buffers/cache: 186 837
Swap: 0 0 0

total = Total RAM available
used = RAM used
Available RAM = RAM guaranteed - Used RAM

You can use the command top -c to see which process is taking more load.

While running the command press + p to sort the process by cpu usage.

To sort it by memory usage press + m.

To exit press +c.

Free memory = RAM guaranteed - Used RAM (384M - used RAM). When the memory usage exceeds the guaranteed RAM, the system forces the processes to release it causing some process to terminate.
