NodeRed Log file location - how to increase more than 100 rows

I am trying to debug a flow (function node) and placed several node.warn statements. I can see the logs in system->logs->nodered logs but this has only last 100 rows. Where can I find the full file or alternatively, how can I increase the file to have more than 100 rows - say 500 rows. Please help!

I added this to the configuration.yaml file, but it did not seem to have any impact on count of nodered log entries.

system_log:
  max_entries: 1000

I usually just write the values I want to monitor to some global variables.
They stay after a run and if you call them step1, step2…and so on,then you know where you are.
