I’m sorry, but I seem to be missing something very basic. I’m trying to make Graylog create incidents in Pagerduty.
Graylog 4.2.11 is running on Debian 10. Package
graylog-server was installed from deb repository.
According to the documentation, graylog-labs / graylog-plugin-pagerduty is not required for versions 4.1+. From this page I understand that a list of notification types should include Pagerduty by default. But my Graylog instance provides only two types of notifications (email and HTTP) plus two legacy alarm callbacks (email and HTTP).
