Description
I get an error when starting my TIBCO Streaming application, indicating my logback configuration is invalid:
2021-08-20 14:18:23.280000-0400 [14544:main] WARN com.tibco.ep.dtm.lifecycle: TIBCO-EP-DTM-00007: user-specified Logback configuration class path resource "logback.xml" at file:/C:/logconfigs/debug/logback.xml is invalid, using product default configurationI have reviewed my logback.xml, but I do not see why it is invalid. How can I troubleshoot further?
Resolution
Use the logback.statusListenerClass Java system property to get more detailed log messages, which should help reveal why the configuration is deemed invalid. You can set this property in your StreamBase Engine HOCON configuration as follows:
StreamBaseEngine = {
jvmArgs = [
"-Dlogback.statusListenerClass=ch.qos.logback.core.status.OnConsoleStatusListener"
]
}
You should now see additional ch.qos.logback.* messages in the console output, for example:
14:06:51,975 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@d737b89 - There is no conversion class registered for conversion word [process] 14:06:51,975 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@d737b89 - [process] is not a valid conversion word 14:09:23,822 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@35dab4eb - There is no conversion class registered for conversion word [transaction] 14:09:23,823 |-ERROR in ch.qos.logback.core.pattern.parser.Compiler@35dab4eb - [transaction] is not a valid conversion word
