[logback-user] Problems with jaino evaluator

[George, Kenneth V [NTK]]

This doesn't work.  I have changed the code, but I get every entry from the logger in the ALARM.LOG file.

Here is what I now have in logback.xml

    <appender name="ALARM" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <evaluator class="ch.qos.logback.core.filter.EvaluatorFilter">
            <expression>
                if (mdc == null || mdc.get("SEND_ALARM") == null)
                return false;

                return true;
            </expression>
        </evaluator>
        <file>logs/alarms.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!-- daily rollover -->
            <fileNamePattern>logs/archive/logFile.%d{yyyy-MM-dd}.log</fileNamePattern>

            <!-- keep 30 days' worth of history -->
            <maxHistory>30</maxHistory>
        </rollingPolicy>

        <encoder>
            <pattern>%date{MMM dd, yyyy hh:mm:ss} %-5level %msg%n</pattern>
        </encoder>
    </appender>

Hi George,

 From what could gather, you want to set an evaluaor[1] not a filter.
You should remove have the enclosing filter element as shown below:

<appender name="ALARM"
           class="ch.qos.logback.core.rolling.RollingFileAppender">

   <evaluator class="ch.qos.logback.classic.boolex.JaninoEventEvaluator">
    ..
   </evaluator>
</appender>

HTH,
