ERROR:NoPaSInstrumentationException: Not instrumented properly with PerformaSure -
Description
I am seeing consistent errors in my Weblogic logs as follows:
< Mar 22, 2010 10:34:05 AM PDT > < Error > < HTTP > < BEA-101017 > < [ServletContext(id=25129151,name=Foglight_J2EE,context-path=/Foglight_J2EE)] Root cause of ServletException.com.quest.foglight.collector.DataSourceException: DataSourceFactory.createDataSource - Failed to load data source com.quest.foglight.weblogic.portal.WebLogicPortalDataSource

Cause
Since you have not integrated your agent with PerformaSure and so the errors are expected

Resolution
Foglight 4 cartridges comes with mainly two components - one, the basic jmx/configuration data and two, Request response time data. Request data is gathered by the PerformaSure technology. If you have not integrated your weblogic server with performasure, you are bound to get such errors in the logs. Since you have not integrated your agent with PerformaSure and so the errors are expected.
Even without performasure technology you are bound to get jmx data in FMS. The errors they see in the logs mean that no request response time data is collected.There are typically 3 types agents in Fog4 cartridge - WebLogic Agent (or WebLogicDomain or WebLogicPortal), RequestTime, J2EEMemory agent. The last two agents are performasure based agents.Also to clarify one more thing, a fog4 customer need not install the â€PerformaSuree†product to collect request response data. The instrumentation agent is packaged in Foglight cartridge itself. Performasure_home is FGL_Home/config/J2EEAgent/<os-arch>. So its normal instrumentation that needs to be done, but you need not install performasure product itself.
