How to enable Log4j level trace when launching a Job on a JobServer from Talend Studio.
Talend Studio log4j JobServer trace level
Talend Data Integration
When executing a job locally from Talend Studio, the log4j trace level can be set in the Run View by clicking the Run tab Advanced settings, then checking the log4jLevel box and choosing the trace level. As a result, the Job log4j messages will be displayed according to the log4j trace level you set for a local Studio Talend job execution.
However, when executing a job remotely on a Jobserver from Talend Studio, the log4j messages won't be displayed according to the trace level you set in the Run View. You need to enable the log4j trace to a level so that when launching a job from Talend Studio on a Jobserver, you will be able to see the log4j trace in the Jobserver logs as well as in the local Talend Studio.
Problem root cause
Solution or Workaround
When a job launched from Talend Studio is executed on a Jobserver, the log4j configuration can be set by performing the following steps in Talend Studio:
Click File > Project properties > Log4j.
Set the trace level in this configuration by changing the priority value:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/' >
<!-- Root Logger -->
<priority value ="trace"/>
<!-- <appender-ref ref="LOGSTASH"/> -->
The log4j level here is set to trace level.
Click OK and Save.
When running the job, you should get the trace on the Jobserver with the log4j level set, as well as in Talend Studio Run View.
