Virtual service specific log is not getting generated under the logs folder. This was working before but not now.
There was change made in the log level to the property "log4j.logger.VSE".
The log level for "log4j.logger.VSE" was set to "ERROR".
The ERROR log level will only write in to the logs when there is any ERROR in the VS. If there were no Errors, the logs will not get generated.
Open the logging.properties from DevTest_Home folder
Change the log level of "log4j.logger.VSE" to INFO and save the file.
Please note the virtual specific log gets generated as soon as there are transactions against this virtual service
