Processamento de Eventos Pendentes Muito Demorado

Microsoft.SystemCenter.HealthServiceModules.WindowsEventLog.ProcessingBackLoggedEventsTooLong (UnitMonitor)

Este monitor verifica se o módulo de Registo de Eventos do Windows está a processar eventos pendentes durante um período de tempo.

Knowledge Base article:

Resumo

Este monitor e alerta indica que o Serviço de Integridade de Gestão do System Center tem processado eventos mais antigos para um determinado registo de eventos maior do que o previsto.

Segue-se um resumo da configuração predefinida deste monitor:

Estado de aviso: Transição para o estado de aviso se o Operations Manager ainda estiver a processar eventos de registo de tarefas pendentes passados 10 minutos. Tal significa que o Operations Manager processou o Evento 25017 (começou a processar eventos de registo de tarefas pendentes), mas não atingiu o registo atual (indicado pelo evento 25018).
Estado crítico: Transição do estado de aviso para o estado crítico se, passados 20 minutos, o Operations Manager ainda estiver a processar eventos de registo de tarefas pendentes. Tal significa que, além dos 10 minutos em que o Serviço de Integridade de Gestão do System Center já esteve a processar eventos de registo de tarefas pendentes, decorreram mais 10 minutos totalizando 20 minutos desde que o Evento 25017 foi transmitido.

Causas

Tanto o estado de aviso como o estado crítico podem indicar que poderá estar a ocorrer o seguinte no agente:

O computador em que foi gerado este evento está a registar centenas a milhares de eventos por minuto que precisam de ser processados, sem exceção, para monitorização.
O computador pode estar com poucos recursos disponíveis (por exemplo, memória).
O Serviço de Integridade de Gestão do System Center ficou parado durante muito tempo e tem de processar todos os eventos a partir do último que processou com êxito.

Resoluções

Pode efetuar as seguintes verificações para determinar a causa raiz do problema:

1. Abra o visualizador de eventos no computador para o qual existe este estado de alerta ou monitor.

2. Verifique se existe uma aplicação ou origem do evento que pareça estar a registar muitos eventos por minuto no registo de eventos

3. Se não existir nenhuma indicação clara da aplicação que possa estar a registar estes eventos, verifique a utilização de recursos neste computador. Se existir uma aplicação que esteja a consumir grandes quantidades de memória ou CPU, consulte o proprietário da aplicação ou o administrador para saber se este comportamento está previsto.

4. Se não estiver preocupado com a perda de monitorização dos eventos existentes, pode limpar o registo de eventos.

Nota: Limpar o registo de eventos quando o Serviço de Integridade de Gestão do System Center ainda está a processar eventos de registo de tarefas pendentes irá resultar na perda de monitorização.
