Hi all,  
Did any of you even have used [https://sentry.io/](https://sentry.io/) for logging?  
How did you implent it with servoy?

Regards,

Gerard Immeker

Servoy uses log4j2 for logging.

Sentry seems to have an integration with log4j, see [https://sentry.io/for/log4j2/](https://sentry.io/for/log4j2/)

I guess if you add sentry-log4j2.jar to the war file, you could modify the log4j2.xml as shown in that page,

Hi Rob,  
I’ve add the jar to the tomcat/lib folder.  
Added the appender to the xml file.  
When we deploy the solution, the error below occours.  
[Fatal Error] log4j2.xml:31:17: Open quote is expected for attribute “dsn” associated with an element type “Sentry”. │  
│ ERROR StatusLogger Error parsing /usr/local/tomcat/webapps/autoflex/WEB-INF/log4j2.xml

Any ideas?  
Regards,  
Gerard

As the error says, your log4j2.xml is probably malformed, there is a missing double quote somewhere.  
Check the quotes for the “dsn” attribute in the appender.
