2 Visão geral

O módulo Monitoramento → Visão geral apresenta uma visão geral do status das triggers ou uma comparação de dados entre vários hosts de uma só vez.

Na barra de título da visão geral estão as opções de apresentação:

  • Localização da informação dos hosts (vertical ou horizontal)
  • Selecionar todos os hosts ou específicos
  • Selecionar todas as aplicações ou aplicações específicas
  • Selecionar o tipo de apresentação (dados ou triggers

Visão geral de triggers

A imagem a seguir apresenta exemplo da visão geral das triggers. São apresentados os estados das triggers (representado por suas cores) em cada host ao qual elas estão associadas:

Observe que as triggers que tiveram modificações recentes (nos últimos 30 minutos) serão apresentadas como blocos piscantes.

Setas para cima e para baixo indicam que a trigger tem dependências, ao passar com o mouse por cima delas as dependências são apresentadas.

Ao clicar em um bloco de trigger é apresentado o menu flutuante de triggers com links relacionados.

Visão geral de dados

A imagem a seguir apresenta exemplo da visão geral de dados. São apresentados os dados de Performance (observe o filtro) de dois hosts.

Apenas dados obtidos nas últimas 24 horas são apresentados por padrão, este limite foi introduzido para evitar problemas de performance ao buscar dados muito antigos. É possível modificar esta limitação ao modificar a constante ZBX_HISTORY_PERIOD no arquivo include/defines.inc.php.

Clicando em um dado será apresentado um menu flutuante com links para gráficos pré-definidos ou dados recentes.

Overview

The Monitoring → Overview section may display either:

  • Trigger overview - an overview of trigger states
  • Data overview - a comparison of data for various hosts at once

The following additional display options are available:

  • select horizontal or vertical display of information in the Hosts location dropdown

Note that there is a hard-coded limit of 50 records displayed. There is no pagination. If more records exist, a message is displayed at the bottom of the table, asking to provide more specific filtering criteria.

Overview of triggers

In the next screenshot Trigger overview is selected. As a result, the trigger states of a local host are displayed as colored blocks (the color of problem triggers depends on the problem severity color, which can be adjusted in the problem update screen):

Note that recent trigger changes (within the last 2 minutes) will be displayed as blinking blocks.

Blue up and down arrows indicate triggers that have dependencies. On mouseover, dependency details are revealed.

A checkbox icon indicates acknowledged problems. All problems or resolved problems of the trigger must be acknowledged for this icon to be displayed.

Clicking on a trigger block provides context-dependent links to problem events of the trigger, the problem acknowledgment screen, trigger configuration, trigger URL or a simple graph/latest values list.

Buttons

Button to the right offers the following option:

Additional information on the page content is displayed if you roll the mouse over this button.

View mode buttons being common for all sections are described on the Monitoring page.
