logback 1.0 - pickup config change & reconfigure

[Sean Kennedy-12]

Some parts of this message have been removed. Learn more about Nabble's security policy.

Hi,

I’m trying to get logback to read an external config xml and “scan” it for changes,

I’ve setup an entry in web.xml and done it via an include..

All looks good when I run it, change is detected in external file , but changes to fillter logging levels are ignored, in fact if I blank the entire external file it’s also ignored !!

 

From ready various other posts this should be possible , it was fixed in 0.9.16 but perhaps I’ve missed something fundamental

I’ve changed the filter up to ERROR and I still get INFO output !!

 

 

Web.xml

      <env-entry>

        <env-entry-name>logback-file</env-entry-name>

        <env-entry-type>java.lang.String</env-entry-type>

        <env-entry-value>C:/logback_properties/localhost/logon.xml</env-entry-value>

      </env-entry>     

 

Logback.xml

<configuration scan="true" scanPeriod="10 seconds" debug="true" >

<insertFromJNDI env-entry-name="java:comp/env/logback-file" as="logback-file" />

<include file="${logback-file}" />

</configuration>

 

Logon.xml  [i.e. external file]

 

<?xml version="1.0" encoding="UTF-8"?>

<included>

 

  <appender name="A1" class="ch.qos.logback.core.rolling.RollingFileAppender">

  

    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">

      <level>INFO</level>

    </filter>

   

    <File>C:/logs/localhost/logon.log</File>

 

    <encoder>

      <pattern>%d{ISO8601} %-5p %c - %m%n</pattern>

    </encoder>

 

    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

      <fileNamePattern>C:/logs/localhost/logon.log.%d</fileNamePattern>

      <maxHistory>2</maxHistory>

    </rollingPolicy>

 

  </appender>

 

  <root level="DEBUG">

    <appender-ref ref="A1"/>

  </root>

 

</included>

Hi Sean,

The on console status listener [1] should give you more information as
to what is going on. Just add the following line just after the
<configuration> element in your top-most config file, i.e. logon.xml.

<statusListener
     class="ch.qos.logback.core.status.OnConsoleStatusListener" />

HTH,

Ceki,
thanks, I'd already got the status listener servlet working..

I've simplified my application to 1 servet, hello world type setup,
Logback will detect and reconfigure a change to an external logback.xml as expected,

However if <include file=...../> mechanism is used it detects the change to the included file but doesn't reconfigure !

Regards,
Sean
