Taxa de coleta de lixo

Microsoft.JEE.PerformanceHealth.GarbageCollectorRateMonitor (UnitMonitor)

O monitor de desempenho para a taxa de coleta de lixo de um servidor de aplicativos.

Knowledge Base article:

Resumo

O monitor de desempenho da taxa de coleta de lixo rastreia a taxa na qual as coletas de lixo estão acontecendo na Máquina Virtual Java associada ao servidor de aplicativos.

Causas

Um estado não íntegro indica que o coletor de lixo excedeu o limite monitorado configurado para o servidor de aplicativos.

Resoluções

Inicie o servidor de aplicativos com uma configuração de memória maior.
Mova alguns aplicativos implantados para outro servidor de aplicativos.
