Hello. I've encountered a very large syslog on a machine running Ubuntu 24.04. Syslog output was disabled. Message level 0 (debug). I have syslog level 1 (Information) selected and enabled output to archive, stdout, and stderr. This behavior was present in build 3018 and the latest 3045, but only on Ubuntu. I'm not sure if this is a bug, so I apologize in advance if I haven't figured out how the logging works.

OpenSCADA doesn't write in the syslog at no setting such option — http://oscada.org/wiki/Special:MyLanguage/Documents/Program_manual#Config

And the log size in whole is dependent only from your project, who generates extra messages!!! ]]> Bug tracker roman Big syslog http://oscada.org/en/forum/posts///10404/ Wed, 24 Sep 2025 16:44:31 +0300 Hello.
