Minha versão do sistema operacional é
[root@m-21-30 ~]# rpm -qf /etc/issue
centos-release-7-3.1611.el7.centos.x86_64
[root@m-21-30 ~]# uname -a
Linux m-21-30 3.10.0-693.5.2.el7.x86_64 #1 SMP Fri Oct 20 20:32:50 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
Os shows gratuitos eu usei 24G
[root@m-21-30 ~]# free -h
total used free shared buff/cache available
Mem: 62G 24G 678M 26M 37G 37G
Swap: 31G 32K 31G
Mas eu uso ps para encontrar toda a memória utilizada pelo processo:
[root@m-21-30 ~]# ps aux|grep -v RSS|awk '{ sum+=$4 }END{print sum*0.01*64}'
6.208
O resultado mostra que eu usei apenas 6G de memória, Abaixo, mostra o processo de 10 melhores usos de memória
[root@m-21-30 ~]# ps aux|head -1;ps aux|grep -v RSS|sort -nr -k4|head

Como eu poderia descobrir para onde vai minha memória?
