Hi,
To debug a running batch processor I created output like 'application.output(“my output”, LOGGINGLEVEL.DEBUG);.
The problem is that I do not see this output appear anywhere.
I expected it to be in the server log, that I can read from the admin pages.
Am I wrong here or should the output appear somewhere else?
Is there a log4j property setting that I have to add to the properties file?
Thanks!

I just run into a similar issue but using the smart client.
Have an error caught within a try/catch
```auto
try{
my code….
} catch (_oErr) {
application.output("ERROR: " + _oErr, LOGGINGLEVEL.ERROR);
databaseManager.rollbackTransaction();
}
```
This is Servoy 7.3.0

Hmm,
I just noticed that the very first output at INFO level is logged.
Everything else is not.
Servoy 7.3.1.

Maybe that’s where the x.x.1 stands for ![:D]( "Very Happy")

Hi Marcel,
You can tell Servoy what logging level you want to see in the various outputs (file, webpage,etc.).
See the log4j.properties option in the servoy admin pages.
For more info see [https://wiki.servoy.com/display/public/ … g+Settings](https://wiki.servoy.com/display/public/DOCS/Server+Log+Settings)
Hope this helps.
Edit: changed the URL to the current version

Debug is not shown by default (or you must set tracing on i guess on the admin page)
if you really want to let it show you can use ERROR or WARN
Or tweak the logging properties as Robert says.

In smart-client this doesn’t seem to work…
Has been a default install, no tweaking on logging properties so far…

in smart client this info will go to the java console.
You will not see this in the server log. (i think there are tools for that)

So in short, all clients running on the server (batch processors, web client, any kind of headless clients really) will log to the server log (when the [logging level permits it](https://wiki.servoy.com/display/public/DOCS/Server+Log+Settings)).
Smart client will only log into the client console (when open) and if you want to log it to the server you need a third-party plugin like Patrick Ruhsert’s [Log plugin](http://www.servoy-plugins.de/plugins/log/log-plugin.html) (which happens to use log4j as well).
