Monitoramento do Gerenciador de Rede Virtual do Azure com logs de fluxo de rede virtual

  • Artigo

O monitoramento do tráfego é fundamental para entender como sua rede está funcionando e solucionar problemas. Os administradores podem utilizar os logs de fluxo de rede virtual para mostrar se o tráfego está fluindo ou bloqueado em uma rede virtual por uma regra de administração de segurança. Os logs de fluxo de rede virtual são um recurso do Observador de Rede.

Saiba mais sobre os logs de fluxo de rede virtual, incluindo o uso e como habilitar.

Habilitar os logs de fluxo de rede virtual

Atualmente, é necessário habilitar os logs de fluxo de rede virtual em cada rede virtual que quiser monitorar. Você pode habilitar os logs de fluxo de rede virtual em uma rede virtual usando o portal do Azure, o PowerShell ou o guia da CLI do Azure.

Veja um exemplo de um log de fluxo:
