@Urbanecm_WMF AFAIK this isn't a problem, but maybe there's something we should do about reducing the log levels?

It's not a user-facing problem, but it logs a lot of INFO-level messages now that most wikis we're deployed to do not have a mentor list. I think WikiConfigException should not be thrown at all if the page is simply missing from the config, as we accept that as a valid configuration. I'll upload a patch that makes a difference between a) mentor list is not configured b) mentor list is configured in an invalid way.

This should stop logging messages for wikis where the mentor list is missing, but keep them if a wiki manages to set an invalid value for the variable (which is probably important for us to know).

Once that patch gets deployed, we might even consider increasing the log level to WARNING (or even ERROR), so invalid list is caught during chores.

This is not a production error; it is logged into a dedicated channel (GrowthExperiments) that does not appear in standard error dashboards.

Moving to sprint, as I uploaded a patch that needs CR.

Checked on wmf.23 - the info-level messages are still present (link for normalized_message:"No mentor available for {user}".
There are also a messages that include individual user names (the same link as for the normalized message).

@Urbanecm_WMF - there should be a follow-up patch as per commit message on https://gerrit.wikimedia.org/r/719061?

Yep yep, moving to In progress again.

This still needs some treatment (see Logstash), but i'm not actively working on this those days.

Checked the link "Mentorship: No mentor available" message in Logstash - a high number of hits just for the one day (363,115).

Thanks for checking that @Etonkovidova. Putting this in the current sprint for us to do something about reducing the volume of Logspam.

@Urbanecm_WMF I think we should do something about this Logspam; is that something you could work on in the context of the GrowthExperiments-Mentorship work?

Message should be gone now (hopefully).
