Picking the errors from log/console

[ipazin]

Hi there @wpardim7,

welcome to KNIME Community Forum!

There are different levels of logging in KNIME and Console so you can have different information in Console and KNIME log file. You want to write down only errors or all messages? If errors only then you can use Try/Catch sequences on multiple places in workflow and write down error in database together with some additional info like timestamp, part of workflow where it failed… I did something similar when building ETL process with KNIME. Otherwise I think you have to go to KNIME log file.

This topic can give you some insight to logging:

Workflow log file rotation workaround

I usually run large and complex workflows that orchestrate many database reading & writing and data modifications performing nodes. In my typical workflow, tens of nodes execute either in parallel or in loops so I usually end up with hundreds of nodes executed at the moment my workflow finishes. In most cases it was hardly usable to solving problems investigating log file KNIME Analytics Platform produces since it doesn’t cover all the workflow. I learnt KNIME writes log entries to a knime.log …
