Configure a separate log file with customizing file name pattern

dieuph — Thu, 26 Sep 2019 04:23:20 -0400

Based on the answer from:

https://answers.axonivy.com/questions/1852/how-can-i-configure-a-separate-log-file-for-the-runtime-log

And:

https://stackoverflow.com/questions/5117758/configuring-rollingfileappender-in-log4j

I see we could customize the file name of the separated log file by using org.apache.log4j.rolling.RollingFileAppender instead of org.apache.log4j.RollingFileAppender Then I try to add log4j-extras (https://mvnrepository.com/artifact/log4j/apache-log4j-extras/1.2.17) to {engine_dir}/plugins. But it doesn't work.

Do I miss anything?

How to change the category name of the log when calling REST client by using Ivy.rest().client(...) ?

Lieu Vo — Thu, 29 Aug 2019 04:11:43 -0400

When I call any REST clients by using Ivy.rest().client(...), it will have the log with the category name [rest_client] from IVY Core. However, I want to make the log messages written into the specific log files of each services. With the same category name for all REST services like this, I could not find any way to configure in log4jconfig.xml to make it correct.

If anyone have ideas to change that category name or change the log4j configuration, please help.

Thanks in advance.

How to find the root cause of error 500, frequently occuring in the logs

SupportIvyTeam — Mon, 13 May 2019 07:02:36 -0400

Some of users of my wf-app seem to face an error 500 while working. The errors show a viewExpiredException as cause of the problem. Generally this points to a session timeout issue. But as the user fires several request within seconds it doesn't make much sense, that one of the requests should fail with error 500 while others can be served as expected.

Unfortunately the behaviour is not 100% reproducible on any dialog. The logs expose the problem for several users but there is no clear pattern to find out which behaviour leads to these errors. Do I have any chance to isolate the real issue behind these error 500 logs?

Log Mail with Log4J SMTP Appender doesn't work

karstenk — Thu, 03 Jan 2019 05:05:38 -0500

Hello, i want Axon Ivy to send an Email when there is an error so i added this code to "log4jconfig.xml":

< appender name="EmailAppender" class="org.apache.log4j.net.SMTPAppender">
        < param name="BufferSize" value="512" / >
        < param name="SMTPHost" value="smtp.gmail.com" / > 
        < param name="SMTPProtocol" value="smtps" / >
        < param name="SMTPPort" value="465" / >
        < param name="SMTPUsername" value=" *** " / >
        < param name="SMTPPassword" value=" *** " / >
        < param name="From" value=" *** " / >
        < param name="To" value=" *** " / >
        < param name="Subject" value="Testing Log4j Mail Notification" / >
        < layout class="org.apache.log4j.PatternLayout">
            < param name="ConversionPattern" value="%-7p %d [%t] %c %x - %m%n" / >
        < /layout >
    < /appender >

  < root > 
    < level value ="WARN" / > 
    < appender-ref ref="FileLog"/ > 
    < appender-ref ref="EmailAppender"/ >
    < appender-ref ref="ConsoleAppender"/ >    
    < /root >

The FileLog works but i dont receive the email. When i change the order to this:

< appender-ref ref="EmailAppender"/ >
< appender-ref ref="FileLog"/ >

then the FileLog and the MailAppender doesn't work.
When i use the same code in an Eclipse Java Project it works and i get the email.

What should i do?

Edit: Do i have to add mail.jar and activation.jar to my build path in Axon Ivy? In Eclipse i added them to lib and it worked but i don't know how to integrate them to Axon Ivy.

Edit2: With Log4j debug=true i get this Error in my logfile:
2019-01-22 16:21:32.230 ERROR [ch.ivyteam.log.LoggerFactory] [main] [] Log4j: Could not configure java.lang.NoClassDefFoundError: javax/mail/internet/AddressException at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2671) at java.lang.Class.getConstructor0(Class.java:3075) at java.lang.Class.newInstance(Class.java:412) at org.apache.log4j.xml.DOMConfigurator.parseAppender(DOMConfigurator.java:247) at org.apache.log4j.xml.DOMConfigurator.findAppenderByName(DOMConfigurator.java:176)
