A alteração no número total de classes Java que foram descarregadas pela Máquina Virtual Java desde que esta foi iniciada.
A regra TotalLoadedClassCountDelta coleta dados de desempenho da Máquina Virtual Java usando uma chamada Stats para um servlet que utilize a consulta /Stats.
A alteração no número total de classes Java que foram descarregadas carregadas pela Máquina Virtual Java desde a consulta /Stats anterior.
Os dados de desempenho são gravados tanto no Banco de Dados do Sistema quanto no Data Warehouse.
