We have installed the CTG server agent as explained in documentation. I the investigatr it only reports GC and few other metrics we are not getting any CTG server metrics

In the logs it reports:

3/12/19 10:07:21 AM CET [ERROR] [IntroscopeAgent.Agent] Introscope AutoProbe will not run because the provided directives files are not valid: Can't proceed because (/CA/WILY/core/config/PPCTGServer-full.pbd:70) the specified tracer class "MethodTraceDecrementor" is invalid.
3/12/19 10:07:21 AM CET [ERROR] [IntroscopeAgent.Agent] Failed to load extensions bundles PBDs
3/12/19 10:07:21 AM CET [ERROR] [IntroscopeAgent.Agent] Unable to instantiate class com.wily.introscope.autoprobe.AutoProbeTransformer
The problem is due to the fact that in the combination of directive files  specified the MethodTraceIncrementor is not mapped to a class.

That mapping is done in the required.pbd

The documentation does show in the example that required.pbd should be at in the property value


introscope.autoprobe.directivesFile=<list of existing PBDs>,PPCTGClientHC-full.pbd,PPCTGServerHC-full.pbd,required.pbd
