java - 使用 Wily Introscope 对基于 Java 的应用程序进行方法级跟踪

Question

我真正想知道的是，我们如何使用 Wily Introscope 对基于 Java 的应用程序进行方法级别跟踪？我想跟踪我的应用程序中存在的所有类的所有方法。请帮忙。

Answer 1

您需要:

IntroscopeAgent.properties 文件中的

introscope.autoprobe.enable=true。然后，您需要为要监视的类构建一个 .pbd 文件。它看起来像:

#Custom Instrumentation for YouApplication
SetTracerClassMapping: ProxyBlamePointTracer com.wily.introscope.agent.trace.hc2.BlamePointTracer com.wily.introscope.probebuilder.validate.ResourceNameValidator
SetTracerParameter: ProxyBlamePointTracer nameformatter com.wily.field.ParameterSubstringFormatter
SetTracerParameter: ProxyBlamePointTracer newmode true
SetTracerParameter: ProxyBlamePointTracer useblame true

SetTracerClassMapping: ProxyExceptionErrorReporter com.wily.introscope.agent.trace.hc2.MethodThrewErrorReportingTracer com.wily.introscope.probebuilder.validate.MetricNameValidator
SetTracerParameter: ProxyExceptionErrorReporter nameformatter com.wily.field.ParameterSubstringFormatter
