Este script manipula o daemon do MRTG das seguintes maneiras:
Start | Stop | Status | Restart

Os caminhos dos arquivos do MRTG podem variar dependendo de como o MRTG foi compilado, neste caso é só alterar as variáveis no começo do script.

No meu Red Hat coloquei o script em /etc/rc.d/init.d e ficou muito bom, facilitando bastante.
