Resumo

A Regra TotalStartedThreadCountDelta coleta dados de desempenho da Máquina Virtual Java com o uso de uma chamada de estatísticas para um servlet usando a consulta /Stats.

A alteração no número total de threads Java que foram iniciadas 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.
