Rodando Proxy e configurando agente local

Feitas as configurações por parte do proxy, estamos prontos para iniciá-lo! Para fazer isso, reinicie o serviço zabbix-proxy:

sudo /etc/init.d/zabbix-proxy restart

Feito isso, verifique se está tudo certo vendo o arquivo /var/log/zabbix-proxy/zabbix-proxy.log
