Gostaria de saber quanto de memória cada processo esta consumindo do seu ambiente, conheça o “ps_mem“.
Com o ps_mem você consegue identificar quanto cada processo esta consumindo de memória e a soma de consumo de todos processos.
Para instalar o mesmo no CentOS é bem simples, siga o exemplo abaixo:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 |

[root@srv-centos ~]# |
Simples não, apos instalar bastar rodar o comando “ps_mem“, segue saída do comando:
