Script simples que tem como objetivo verificar o consumo de memória dos processos.

Alterar a variável "file = open(home_dir + "/scripts/.Config", "r")" para o caminho onde encontra-se seu arquivo de configuração contendo os nomes dos processos que deseja-se monitorar:

Ex.:

cat .Config

logstash
metricbeat
elasticsearch
kibana

check_process.py
