Page not found for Prometheus metrics endpoint about graylog-plugin-metrics-reporter

You need to add configurations to your server.conf according to the Readme:

Well, I take it you mean changes the Prometheus configuration file (prometheus.yml) rather than server.conf, since there is no reference to server.conf on that page?

Either way, that still doesn't work. The problem isn't Prometheus, it's the exposed /metrics endpoint on the Graylog server. A simple browser request to that endpoint returns the Page not found message. (And, a 200 status code rather than a 404 as well just to add to the overall confusion.) It's Graylog that's the issue here, not Prometheus.

@AtebMT I am unable to reproduce your issue with a Graylog 3.x setup. Accessing the prometheus API endpoint via curl and the browser works fine:

If this is still relevant, please re-open the issue with some more details about your setup. (especially server logs) Make sure to update to the latest stable release (3.0.2 as of this writing).

Thank you!
