Based on the documentation, there should be no plugin needed for Slack notifications to work in 4.0. But i don’t see the option there either. It would be great if somebody from Graylog could give us a clue.
Update: So everything works fine on my ubuntu graylog v4.0.1+6a0cc0b, but i don’t see the Slack notification type on my os x graylog (also v4.0.1+6a0cc0b), which was installed through tgz, so maybe it’s something missing there.
Thank you, i put the jar in /usr/local/graylog/plugin/ on my osx installation and it works fine. Yes, i was using tarballs.
It would be great if you could include this information in the documentation at
