Description of problem:
SELinux is preventing ps from 'search' accesses on the diretório lightdm.

*****  Plugin catchall (100. confidence) suggests   **************************

Se você acredita nisso ps deve ser permitido search acesso no lightdm directory por padrão.
Then você deve informar que este é um erro.
Você pode gerar um módulo de política local para permitir este acesso.
Do
permitir este acesso por agora executando: # ausearch -c 'ps'--raw | audit2allow -M my-ps # semodule -X 300 -i my-ps.pp

Hi alamar, 

I close multiple your issues related to pcp and SELinux. Let's discuss it in this bugzilla ticket.

Are you able to reproduce it? It looks like mislabeled system. Could you please attach output of: 

# ps -efZ | grep pcp_

Thanks,
Lukas.
