Monitoramento de rede com o Bandwidthd
Dica publicada em Linux / Introdução
Monitoramento de rede com o Bandwidthd
Esse monitoramento de rede serve para ver quais sãos os protocolos que estão sendo mais usados e ver o consumo de banda de cada host na rede, ele gera um gráfico muito bom e através desse gráfico você fica com uma visão melhor da sua rede para fazer um controle de banda ou QOS.
Instalação dos programas necessários:
1. O bandwidthd monitora os protocolos acessados pelas maquinas da rede, ele deve ser instalado no gateway da rede.
2. Instale o servidor Apache e o bandwidthd:
# apt-get install apache2 bandwidthd
Configuração do Bandwidthd:
3. Vamos agora para a configuração do bandwidthd.
3.a. Com o seu editor predileto vamos com figurar o bandwidthd.
# mcedit /etc/bandwidthd/bandwidthd.conf
# mkdir /var/www/bandwidthd
# chmod 775 -R "/var/www/bandwidthd
# /etc/init.d/bandwidthd stop
# /etc/init.d/bandwidthd start
3.b. Agora é só acessar o seu servidor pela web.
http://localhost/bandwidthd
