[logback-user] Flushing problem

[Harish Krishnaswamy]

Hi Ceki,
I am using the RollingFileAppender and the SMTPAppender. And actually I get
the email but its just not going to the file which makes me believe that its
just not getting flushed. I am listing the shutdown task and the logback
config. I appreciate the help!

<configuration>

    <appender name="FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>file.log</file>

        <rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>file-%d{yyyy-MM-dd}.log</FileNamePattern>
        </rollingPolicy>

        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>%date %level [%thread] [%logger{0}] %msg%n%ex</Pattern>
        </layout>
    </appender>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>%msg%n</Pattern>
        </layout>
    </appender>

    <root>
        <level value="info" />
        <appender-ref ref="FILE" />
        <!-- appender-ref ref="STDOUT" /-->
    </root>

    <appender name="EMAIL" class="ch.qos.logback.classic.net.SMTPAppender">
        <SMTPHost>smtp.gmail.com</SMTPHost>
        <SMTPPort>465</SMTPPort>
        <SSL>true</SSL>
        <Username>user at gmail.com</Username>
        <Password>pwd</Password>

        <To>id at domain.com</To>
        <From>name at gmail.com</From>
        <Subject>Stats - %m</Subject>
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>%msg%n</Pattern>
        </layout>
    </appender>

    <logger name="email">
        <level value="info" />
        <appender-ref ref="EMAIL" />
    </logger>

</configuration>


        return new Runnable()
        {
            public void run()
            {
                // If another thread cleared this task then return
                if (_shutdownTask == null)
                    return;

                _shutdownTask = null;

                _logger.info("Importer shutting down...");

                // Log stats
                if (_piLoader != null)
                {
                    PiStats stats = _ctx.get(PiStats.class);

                    Logger emailLogger = LoggerFactory.getLogger("email");
                    emailLogger.info(stats.toString());

                    String hostName = null;

                    try
                    {
                        hostName = InetAddress.getLocalHost().getHostName();
                    }
                    catch (UnknownHostException e)
                    {
                        hostName = "Unknown host";
                    }

                    // This will trigger the email
                    // user.name and host will indicate the environment this
message is coming from
                    emailLogger.error(System.getProperty("user.name") + " -
" + hostName);
                }

                // Cleanup state

                // This will give any open SqlSessions a chance to finalize
                // System.runFinalization();

                _runningToken.delete();

                _logger.info("Importer shutdown complete.");

                LoggerContext lCtx = (LoggerContext)
LoggerFactory.getILoggerFactory();
                lCtx.stop();
            }
        };
