Logging in Talend.

Anonymous — Sat, 16 Nov 2024 12:47:56 GMT

Hi,
I'm currently using tLogCatcher to catch errors to file. I want to be use log4j to create logs because I want to be able to rotate the log.
I've looked into using tLog4J but I can't seem to understand how to use it and define a properties file for it. Can tLogCatcher in some combination be used to rotate log? how can I use tLog4J for this?

Hi
tLog4j should be used with tLog4jCatcher and tInitLog4j together, here is an example job shared by bcourtine on Talend exchange.

There is components in 4.2.2. the tLog4J is self contained.

Hi
The path of logs file is defined in the log4j.xml file, and you need to specify the path of log4j.xml file on the tInitLog4j component.

	<appender name="DailyFileAppender" class="org.apache.log4j.DailyRollingFileAppender">
	<param name="DatePattern" value="'.'yyyy-MM-dd"/>
	<param name="File" value="d:/file/test/logs_test.log"/>
	<param name="Append" value="true"/>
	<layout class="org.apache.log4j.PatternLayout">
		<param name="ConversionPattern" value="%d{HH:mm:ss,SSS} %-5p %c{2} - %m%n"/>
	</layout>
	</appender>

You can find an example job that using log4j components on Talend Exchange.

you have to create web project and add configuration of log4j into web.xml as following

<context-param>
<param-name>log4jConfigLocation</param-name>

<param-value>file:${automation.prop.folder}/TALEND_PROPERTIES/log4j.xml</param-value>
</context-param>
<listener>
<listener-class>
org.springframework.web.util.IntrospectorCleanupListener
</listener-class>
</listener>
<listener>
<listener-class>
org.springframework.web.util.Log4jConfigListener
</listener-class>
</listener>

Hello Ppl,
can we change the log4j.xml file to get the Error log output in a file instead of console ?
If Yes, could you please tell me how.

Thanks,
Abhijit
