Rocket.Chat Plugins

The Rocket.Chat plugins talk to the Rocket.Chat REST API. They need a user that holds the view-statistics permission (the stats API is not public).

Plugins in this group

  • rocketchat-stats: total and active users, online users, channels, messages, uploads and file-storage usage.
  • rocketchat-version: installed Rocket.Chat version, EOL check.

Authentication

Create a dedicated Rocket.Chat user with permission to read statistics. How you grant the permission depends on the edition.

Rocket.Chat Enterprise Edition

Custom roles are an Enterprise feature. In the admin area (top-left avatar menu > Administration):

  1. Permissions > New Role: name stats, scope Users, grant only the View Statistics permission, Save.
  2. Users > New: username rocket-stats, assign a password manually, add the stats role under Roles, Save.

Rocket.Chat Community Edition

CE does not allow creating custom roles through the UI; you repurpose a built-in role instead.

  • Simple: create rocket-stats with the built-in admin role. Overprivileged but one step.
  • Narrower: in Administration > Permissions, tick View Statistics on the built-in bot role, then create rocket-stats with the bot role. The bot role also exempts the user from rate limits, which is acceptable for a monitoring account.

Invoking the Plugins

The plugins are then called with --url (e.g. https://rocketchat.example.com/api/v1), --username=rocket-stats and --password.

Common parameters

Shared across both Rocket.Chat plugins (run <plugin> --help for the full list):

  • --url: Rocket.Chat API base URL. Default http://localhost:3000/api/v1.
  • --username / --password: credentials of the monitoring user.
  • --insecure: skip TLS certificate verification.
  • --no-proxy: ignore HTTP_PROXY / HTTPS_PROXY.
  • --timeout: network timeout in seconds.

Service Sets in the Icinga Director Basket

The shipped basket activates both Rocket.Chat plugins through one Service Set, assigned via the rocketchat tag on the host:

  • Rocket.Chat Service Set: runs rocketchat-stats and rocketchat-version against the stats user above.
