#### Visão geral

Através deste módulo *Relatórios → Relatório de disponibilidade* você
pode visualizar a proporção de tempo que cada trigger passou no estado
de OK/INCIDENTE.

Assim, fica facil determinar a disponibilidade de vários elementos do
seu ambiente.

Na barra de título é possível selecionar o modo de exibição (por host ou
por triggers de um template). Após isso utilize o filtro para restringir
melhor o que deseja visualizar e o período.

O nome de cada trigger possui um link para os últimos eventos dela.

Clicando no link *Mostrar* na coluna *Gráfico* irá apresentar um gráfico
de barra com a disponibilidade semanal no último ano.

A parte verde das barras representa o estado OK e a vermelha o estado de
INCIDENTE.

groups.
