A service’s verbosity influences the way the log messages reach Distributed Logger and their quantity. If a service (such as RTI Persistence Service, RTI Routing Service, or another service that is integrated with Distributed Logger) is configured with a low verbosity, it will not pass a lot of messages to Distributed Logger, even if the Distributed Logger filter level is set to a very verbose one (such as TRACE). On the contrary, a high verbosity will work better, because it will pass more messages to Distributed Logger; in this case the filter level will have more effect.
Note: Since Distributed Logger uses a separate thread to send log messages, there is little impact on performance with more verbose filter levels. However, there is some performance penalty in services that use a higher verbosity.
