Hi all,

Can anyone provide me with details of how to make changes to DHIS2 Tomcat logging levels?

I have tried editing logging.properties in [BASE]/conf, and turning off logging (and various other attempts at different levels, such as SEVERE, WARNING, etc) using the folling settings:

Hi Jason,

did you look at this section in the docs?

[http://dhis2.github.io/dhis2-docs/master/en/implementer/html/ch08s08.html](http://dhis2.github.io/dhis2-docs/master/en/implementer/html/ch08s08.html)

Hi Lars,

Yep – and unless I’ve dropped a few IQ points, I can’t see where it tell you how to adjust the logging levels.

It explains the extra logging I referred to, but doesn’t tell me how to change anything in the default logging, unless I am being daft?

I don’t want to use log4j, or anything else; I just want to stop the thing from logging authentications…

Am I being daft?

Best,

Jason.

Not daft (well not completely daft). You cannot change the default logging configuration. It is set programmatically in java.

Your option is to create a custom log4j configuration as per the documentation.

In production you might want to do this anyway, rather than rely on the baked in configuration. Some time ago I produced a log4j configuration file which mimiced the behaviour of the hard coded configuration but I lost it - I know, I should have committed it somewhere but I didn’t. Now I will (eventually) have to do it again.

(An alternative future approach might be to allow some of these things to be fine tuned in the settings through the ui but this is currently not possible)

Hi Jason,

we do use log4j for logging so you need to use the log4j configuration syntax to modify the behavior.

You can do this to raise the log level for the spring authentication, try something like this in your log4j.properties:

springframework.security.web.authentication = ERROR

Aha,

Now it all makes sense…

I did manage to break the logger altogether, which had the same effect as switching it off:

I changed the line below to read:

log4j.rootLogger = OFF

in the properties file, and it stopped logging – at least, apart from logging an error about the logger not being configured properly…. J

Same net result, and no harm done, since it’s a test sandbox.

Thanks for the feedback, guys – much appreciated.

If I have anything useful to contribute once I am finished, I’ll mail it.

Kind regards,

Jason.

Some time ago I produced a log4j configuration file which mimiced the behaviour of the hard coded configuration but I lost it - I know, I should have committed it somewhere but I didn’t. Now I will (eventually) have to do it again.
