Is there any way to enable logging for specific service ?

[Rahul Verma]

Folks,
We have performance VSE in our project and transactions rates are too high .Almost no logging is enabled due to performance constraints.
WARN logs don't show anything helpful for debugging 
Is there any way to enable logging for a specific service based on name or anything else .
I am facing issue on one of the service where intermittenlty it is not able to match any response in VSI.
Issue is simple there might be a incoming requets that is not matching but finding that trnasaction is not possible without logging due to high TPS .
Possibly vse_matches logs will help if enabled for that servcie

Hi Rahul
First, try enabling DEBUG level log as well as VSE log. Repro
the non-matching problem and go through the logs. If you find any specific
package/class that gives the information that you need for diagnosis, then
make a note of that class.

Now you can add a class Specific DEBUG level logging. Shown below is an
example specific to version 10.7.2

Assuming that the class that you are interested in is "
com.itko.lisa.ws.rest.RESTNode"

This is how you could add a DEBUG logger exclusive to this class by editing
LISA_HOME/logging.properties file:

Define the logger:

logger.nonmatching.name = com.itko.lisa.ws.rest.RESTNode
logger.nonmatching.level = DEBUG
logger.nonmatching.additivity = false
logger.nonmatching.appenderRef.A1.ref = A1

Add the logger to the list of loggers:

loggers = nonmatching,<existing loggers="">

Save the file. No need to restart your services.

With the class specific DEBUG logging in place, you can retain ROOT logger
at WARN or ERROR level to optimize the performance of VSE.

Hi Sankar,
Thanks for your reply .
But i can't enable DEBUG mode that will hamper server perfromance because for all the services we have very high TPS almost 24*7
Can it be done at service level ?
