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> -----Original Message----- From: logback-user-bounces@qos.ch [mailto:logback-user-bounces@qos.ch] On Behalf Of ceki Sent: Friday, June 22, 2012 2:54 PM To: logback users list Subject: Re: [logback-user] Problems with jaino evaluator 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, [1] http://logback.qos.ch/manual/appenders.html#smtpAppender_Evaluator On 20.06.2012 19:34, George, Kenneth V [NTK] wrote:

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</fileNamePatt ern>

<!-- 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.

Ok, so I made the change and I do not get the error now. However, I still am getting text in the alarm.txt file that should not be there. I changed the evaluation for level > INFO to be level == ERROR. I am still getting info and debug messages in the alarm file. Also, SEND_ALARM has not been set in the code, yet I am getting log messages.

I clear-out the logs before I start my app. I am using earlier versions of the libraries though... logback-core-1.0.0.jar logback-classic-1.0.0.jar slf4j-api-1.6.4.jar From: logback-user-bounces@qos.ch [mailto:logback-user-bounces@qos.ch] On Behalf Of Tony Trinh Sent: Friday, June 22, 2012 4:11 PM To: logback users list Subject: Re: [logback-user] Problems with jaino evaluator On Fri, Jun 22, 2012 at 4:58 PM, George, Kenneth V [NTK] <Kenneth.V.George@sprint.com<mailto:Kenneth.V.George@sprint.com>> wrote: Ok, so I made the change and I do not get the error now.

I can't reproduce your symptoms (my alarms.log contains only messages that pass the filter). Are you sure you're not looking at a stale log? What library versions are you working with?
