introscope.autoprobe.enable
This property enables and disables AutoProbe.
"Autoprobe' is the entry point to instrument classes.
When the property set to 'true' it loads the pbd files and decide what to instrument and so on.
When the property set to false , the autoprobe is disabled. It means, the Agent will load but will not instrument any classes / methods.
But there are some features do not need instrumentation will get metrics even the autoprobe is disabled. Like EM host and Port.
The features need instrumentation will not gather metrics when its disabled.
