How can I set a reasonable time format for Java logging entries in Crowd 3?

Question

Hello!

In Crowd 2 I could simply add to apache-tomcat/conf/logging.properties the line

< 1catalina.java.util.logging.SimpleFormatter.format=%1$tF %1$tT %2$s%n%4$s: %5$s%6$s%n

and I had a time format that I could understand. Crowd 3 looks pretty different. Where and how can I set here a reasonable time format for logging?

Hello Marcin!

The migration from Crowd 2.12.0 to version 3.1.2 fails every time, but at least I can see that the log files contain a reasonable date format. (Which I might adjust later, now that I know where to perform this task.)

Thank you!

Hi @iron.werther

In Crowd 3.x we've updated version of Tomcat which is bundled inside Crowd from 7.x to 8.5.x

In Tomcat 7, the log format configuration looked like:

java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

thus by changing the

1catalina.java.util.logging.SimpleFormatter.format

you could adjust the date format in logs.

In newer version of Tomcat (8.5.x bundled in Crowd 3.x) this config looks like:

java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = org.apache.juli.OneLineFormatter

notice that the formatter has changed.

I believe you may try to change the time format in logs by adjusting the tomcat's logging config as follows:

java.util.logging.ConsoleHandler.formatter = org.apache.juli.OneLineFormatter
org.apache.juli.OneLineFormatter.timeFormat = yyyy-MM-dd HH:mm:ss

(the timeFormat - is using the SimpleDateFormat syntax)

Unfortunately I did not test that on a working Crowd version, this is what I got by following the Apache Tomcat docs.

Hope that helps,
