The Performance tool presents statistics about an interactive user process. Your application can record many similar statistics for services execution in the SERVICES-PAL log, which is accessed by clicking Designer Studio > System > Operations > Logs.
The log file is in a Comma-Separated-Values format. Each row of the CSV file corresponds to a service interaction.
To enable service logging:
<Logger name="ServicePAL" level="debug" additivity="false">
<AppenderRef ref="SERVICES-PAL"/>
</Logger>
