Adapt log4j config after deploying

Anonymous — Sat, 16 Nov 2024 04:07:55 GMT

Hello,

I have made a lot of job in Talend Data Integration Studio.

Now, I would like to put log info in the log server. I have found a solution with the edition of the project properties to update the log4j file to activate the logstash appender. It's good for new jobs.

Is it possible to update the log4j file for already deployed job ?

If yes, where I can find the log4j config file ?

Thanks in advance

Dimitri

Hi Dimitri
Are you using Talend Enterprise subscription product and the job has been deployed to TAC?

Hello,

Yes, I use Talend Enterprise subscription and use TAC.

I would like to add the logstash appender only when I deploy on TAC.

If I modify the log4j file in project, when I run in local in Studio, I have an error message from log4j.

How I can configure log4j to have logstash appender only on job deployed in TAC ?

Thanks in advance

Dimitri

Hi,
Tac doesn't allow to modify the existing appender or add new appender in the log4j.xml, because tac integration the log4j inside, and load the file appender with the setting in configuration page. also tac remove the feature to send logs to logstash, instead to use:
- audit log
- logserver use filebeat to collect the logs
which would release the press on tac.
Hope that helps you!
