Apache Thrift server logs - scala

Question

I have a server which has implemented in scala.
import org.apache.thrift.server.TServer
import org.apache.thrift.server.TThreadPoolServer
import org.apache.thrift.transport.TServerSocket
import org.apache.thrift.transport.TTransportException
import hms.config.demo.AppStoreConfig
object Server {
def main(args: Array[String]) {
start
}
private def start {
try {
val serverTransport: TServerSocket = new TServerSocket(7911)
val processor = new AppStoreConfig.Processor(new AppStoreConfigImpl)
val server: TServer = new TThreadPoolServer(new TThreadPoolServer.Args(serverTransport).processor(processor))
println("Starting server on port 7911 ...")
server.serve
}
catch {
case e: TTransportException => {
e.printStackTrace
}
}
}
}
I need to get logs from the server. That means how it handles the requests and respond to clients like tomcat server. Is there a way to achieve my task in thrift server?

It depends on slf4j as you can see here in "depends on". Here is documentation on how to configure slf4j: http://slf4j.org/faq.html. Basically you start by making a config file src/main/resources/logback.xml and putting something like this into it:
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
<file>/var/log/mysuperapp/supername.log</file>
<append>true</append>
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<logger name="org.apache.thrift.server" level="info" />
<root level="info">
<appender-ref ref="FILE" />
</root>
</configuration>
Pick the appropriate level for desired package, add multiple lines for multiple packages. This requires you to have logback dependecy/jar present on classpath.
