I got GUID zero in transaction trace when I deployed struts2 field pack

[Sam Lin]

Hi,

 

I download the struts2 field pack from community and deployed it into Agent r9.7.1.0.

Then I found so many transaction trace that showing abnormal in trace view.

 

 

There are my step for deploy struts2 field pack.

 

1. copy struts2.pbd and biz-trx-struts2.pbd into <Agent_HOME>/core/config

2. copy struts2Monitoring.jar into <Agent_HOME>/core/ext

3. setup the setting in IntroscopeAgent.profile as below

introscope.autoprobe.directivesFile=webligic-typical.pbl,struts2.pbd,biz-trx-struts2.pbd

introscope.agent.decorator.enabled=true

4. enable the setting in biz-trx-http.pbd as below

SetTracerClassMapping: BizTrxHttpTracer com.wily.introscope.agent.biztrxhttp.trace.BizTrxHttpTracer com.wily.introscope.probebuilder.validate.ResourceNameValidator

SetTracerOrdering: BizTrxHttpTracer -2005

SetTracerParameter: BizTrxHttpTracer nameformatter com.wily.introscope.agent.trace.biz.trx.BizTrxNameFormatter

SetTracerParameter: BizTrxHttpTracer errorTracing true

 

Then Struts can working normally but only GUID's value is zero

 

So, any ideal about this?

 

Thanks,

Sam

Hi Sam,

I found a similar symptom struts2/GUID=0 internal reference where the ServletHeaderDecorator code was not trapping 0 values for the GUID. Andreas reian06  worked on it but he is out until Dec 21, but Guenter Guenter_Grossberger or Hiko Hiko_Davis may be able to help.

I do know there were updates done by myself to the Communications Tracer specifically for Struts2 and those changes were rolled into APM 10.1 (or 10.2; I will need to recheck my notes).

Hi Sam,

I spoke with Guenter and I am attaching a desktop fix version of 9.7.1 ServletHeaderDecorator.jar which contains modified version of this class:

com.wily.introscope.agent.servletheaderdecorator.common.GUIDUtilsReflected

Please:

• stop the agent
• backup your existing version of AGENT_HOME\wily\core\ext\ServletHeaderDecorator.jar & replace with the new version from the zip file
• restart the agent.

Please let us know how you go.

 

Thanks

Hi Sam,

Just checking if you have managed to retest with the new jar file and if you are now seeing non-zero GUID values?

 

Thanks
