log4j2:Providing log file location and log4j.xml configuration file through context variables

[aksharma]

Hi

I am migrating from log4j1( 6.2.1) to log42 (7.3.1)

Earlier we used to manually initialize the log4j through tlog4jinit and set the log file name and location through system. set in jobs.

Now we are planning for upgrade and want to use the talend provided log4j2 framework

I see the help document https://help.talend.com/r/9TuKg6zZZmEHit1Ntl3pOw/2kpRuWQFjIGun6Lj6H31ww

Just wanted to check if I can configure something like attach file and set default value for context.logfilename and context.logbasepath variable in the job .Basically I want to provide user to configure the log file name and location.

I tried multiple option but nothing is working. Need help

Hello,

Usually, we use log4j to capture the log message and it doesn't support context variable.

Is it working when you use the ${TalendJob.log}? Which creates a log file with the Talend's job name.

Hi

Thanks for reply

yes ,it works with ${sys:TalendJob.log} but we want to control location of log file generation as well as the log4j.xml file location

We can achieve this with  

<RollingFile name="RollingFileAppender" fileName="${log4j:configParentLocation}/${sys:TalendJob.log}" >

but we have to pass the log4j.xml file location through jvm parammeters

-Dlog4j.configurationFile=C:\Users\aksharma\Downloads\testlogs\log4j2.xml

But I am not sure if multiple job/service artifacts can use same location of log4j2.xml file

how we can achieve same for multiple rest services generating multiple log files running under same karaf container
