Hi Arsene, GafferConfigurator (the groovy configurator in logback) does not support appender-ref elements. Please enter a jira issue so that we can track this omission. Best regards, -- Ceki http://twitter.com/#!/ceki On 17.04.2012 09:52, Arsene Lee wrote:

Hi,

I’m using Logback with groovy configuration. I want to use Perf4j with Logback but I’m having problem with the groovy configuration.

I want to add an AsyncCoalescingStatisticsAppender. The XML confugration looks like this.

<appender name="CoalescingStatistics" class="org.perf4j.logback.AsyncCoalescingStatisticsAppender">

<param name="TimeSlice" value="60000"/>

<appender-ref ref="graphExecutionTimes"/>

<appender-ref ref="graphExecutionTPS"/>

<!-- We add the JMX Appender reference onto the CoalescingStatistics -->

<appender-ref ref="perf4jJmxAppender"/>

</appender>

I don’t know how to translate it into groovy’s configuration. Especially the the appender-ref ref part. I tried the logback.xml to logback.groovy translator to translate but it generates which I don’t think it is correct.

appender("CoalescingStatistics", AsyncCoalescingStatisticsAppender) {

param =

appender-ref =

appender-ref =

appender-ref =

}

Regards,

Arsene
