PagerDuty plugin: notification type not showing up

Goal:

Send alerts to PagerDuty.

Steps:

  1. Download https://github.com/graylog-labs/graylog-plugin-pagerduty/releases/download/2.0.0/graylog-plugin-pagerduty-2.0.0.jar
  2. Place the download in plugin_dir (/usr/share/graylog-server/plugin)
  3. Restarted graylog-server

Expected result:

When adding a new notification, ‘PagerDuty’ is shown as ‘Notification Type’ option, as shown in the README: https://github.com/graylog-labs/graylog-plugin-pagerduty#usage

Actual result:

‘PagerDuty’ does not show up as ‘Notification Type’ option.

Logs:

The plugin is loaded:

2020-11-13T11:20:16.252+01:00 INFO  [CmdLineTool] Loaded plugin: PagerDutyNotificationPlugin 2.0.0 [org.graylog.plugins.pagerduty.PagerDutyNotificationPluginPlugin]

A script is included in Graylog web pages, indicating it has loaded successfully:

<script src="https://graylog0.cyberfusion.cloud/assets/plugin/org.graylog.plugins.pagerduty.PagerDutyNotificationPluginPlugin/plugin.org.graylog.plugins.pagerduty.PagerDutyNotificationPluginPlugin.5a86547f788cd5489c6c.js"></script>

What have I tried:

I found this post from January, but the README says: “Required Graylog version: 3.3 and later”, making me believe this information is outdated.

Question:

How do I get ‘PagerDuty’ to show up as ‘Notification Type’ option?

Turns out I did update Graylog to version 3.3, but forgot to restart the service :). Now running version 3.3 and the plugin works well.
