There are several groups to whom a WMF-hosted or self-hosted Sentry instance could be interesting:
- Labs tool maintainers could use the beta Sentry instance to log errors. This works for web services as well as bots run on Labs (or your own machine, for that matter)
- owners of 3rd party wikis can use Sentry to easily collect PHP + JS errors
- may be useful for mobile apps / desktop tools?
I'll hold a short presentation/demo about Sentry, then those who are interested can stay for a hacking session. I expect the presentation part will be ~15 mins.
