Is there a way to increase the number of logs?
As far as I understand the logs can be found under Diagnostics > Logs, as well as in the file system under Inductive Automation\Ignition\logs. There are only 6 log wrappers available.
My logs run out and override itself in less than a day. Is there a way to increase the number of logs?
I don’t know about the log database, but there are settings in ignition.conf that control the wrapper log size limit, number of kept files, and naming. Read the comments in ignition.conf.
The system_logs.idb file is generated by Ignition and controlled through a custom logback appender; you can change logback.xml to change the retention target from the default ~50,000 events:
