Taxa de alteração de tempo do compilador JIT da JVM

Microsoft.JEE.ApplicationServer.PerformanceData.TotalCompilationTimeDelta (Rule)

A alteração no tempo de compilação entre amostras do compilador JIT (Just-In-Time) da Máquina Virtual Java.

Knowledge Base article:

Resumo

A regra GCCollectionCountDelta coleta dados de desempenho da Máquina Virtual Java com o uso de uma chamada de estatísticas para um servlet usando a consulta /Stats; depois, a regra calcula a diferença entre os valores de amostra atuais e os anteriores.

A alteração no tempo de compilação entre amostras do compilador Just In Time da Máquina Virtual Java.

Os dados de desempenho são gravados tanto no Banco de Dados do Sistema quanto no Data Warehouse.
