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>

Good afternoon.
I have a situation where I need to log information to 2 separate files,
but under different conditions, for the same context/class files.
Basically, I have 2 files: 1 log, 1 alarm_log.
I need to set the level for reporting to INFO, but only log WARN/ERROR
messages to alarm_log when a MDC value of “SEND_ALARM” is set. I have
tried to place a <filter> of type
“ch.qos.logback.core.filter.EvaluatorFilter” and cannot seem to get it
to work, messages of Level INFO show-up in the alarm_log.
Can this even be done (maybe I am just using it wrong)? Here is the
section of my logback.xml file specifying the appender:
<appender name="ALARM"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<filter class="ch.qos.logback.core.filter.EvaluatorFilter">
<evaluator>
<expression>
if (mdc == null || mdc.get("SEND_ALARM") == null)
return false;
return true;
</expression>
</evaluator>
</filter>
<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>
Thanks.
