Discourse Docker インスタンスで prometheus-exporter プラグインを有効にする

[Falco]

@Martin_Lim

Is there something special Discourse normally does with puma to ensure that the prometheus-exporter can open a TCP connection on port 9405?

If you install Discourse following the official install guide it won’t use Puma, but Unicorn. All our plugins and themes assume an install that follows the official install.
