[one-users] datastore log info missing from oned.log in v4.2

[Gary S. Cuozzo]

Then it seems that this has changed since the 3.8.x series.  I use log_debug script function to log various messages in my drivers.  I have my log level set to DEBUG in conf file.  I used to see those messages, as I would expect, unless I changed the log level to something above DEBUG.  The messages were logged regardless of the outcome of the script.

It seems that if that is no longer the case, then the log facility can't be used for anything other than error conditions and having DEBUG, INFO, etc. is not very useful anymore.

Maybe I'm missing the point of the feature, but it definitely did not work this way before and was something I relied on for certain things.  I'm now overriding the log_debug function locally in my script and writing the output to my own log file.  That is not as nice because now the log entries are not intertwined with other events which are happening in the oned.log file.

IMO, any message should be written to the file based on the configured log level.

Let me know your thoughts.

Thanks for the reply,
gary

STDERR is only logged when the action is not successful, maybe that is
your problem.

It was related to a bug fix where the SRC & DST arguments to pre/postmigrate were swapped.  I simply had to swap them back.  The irony in it is that I was the one that suggested the pre/postmigrate feature request and reported that bug.  ;)

Even if I changed the logs from log_debug to log_error, still no output.  I'll try forcing exit 1 to see if that causes the logs to show up.

I did not have time to work on this, so the server sat for a few weeks.  Now I'm back to working on it and not seeing the messages.  Very odd.
