Installation

Clone the GitHub repo and run:

$ python setup.py install

Or, to install remotely from GitHub run:

$ pip install git+https://github.com/alerta/alerta-contrib.git#subdirectory=plugins/rocketchat

Note: If Alerta is installed in a python virtual environment then plugins need to be installed into the same environment for Alerta to dynamically discover them.

Configuration

To configure the Rocket.Chat plugin start by setting up an Incoming Webhook integration for your Rocket.Chat channel. Login to Rocket.Chat and go to "Administration" => "Integrations" => "New Integration" => "Incoming WebHook".

Enable the webhook, assign a webhook name, default channel (eg. #general) and username to post messages as (which must already exist).

Note: No integration script is needed so leave the "Script" box blank and disabled.

Save the changes and take a copy of the webhook URL.

Add rocketchat to the list of enabled PLUGINS in alertad.conf server configuration file and set plugin-specific variables either in the server configuration file or as environment variables.

PLUGINS = ['rocketchat']
ROCKETCHAT_WEBHOOK_URL = 'https://my.rocket.chat/hooks/TOKEN'
ROCKETCHAT_CHANNEL = ''  # if empty then uses channel from incoming webhook configuration

ICON_EMOJI = '' # default :rocket:
ALERTA_USERNAME = '' # default alerta

The DASHBOARD_URL setting should be configured to link Rocket.Chat messages to the Alerta console:

DASHBOARD_URL = ''  # default="not set"

Example

PLUGINS = ['reject','rocketchat']
ROCKETCHAT_WEBHOOK_URL = 'https://alerta.rocket.chat/hooks/Ahqyy84yFB4DuWorQ/ZyndPtdbY5PCnaQGsXTJPCXbNC9bDiTL9L2Q7ktLnuHFYNKd'
DASHBOARD_URL = 'http://try.alerta.io'

Troubleshooting

Restart Alerta API and confirm that the plugin has been loaded and enabled.

Set DEBUG=True in the alertad.conf configuration file and look for log entries similar to below:

2018-08-15 01:49:52,323 - alerta.plugins[36667]: DEBUG - Server plugin 'rocketchat' installed. [in /Users/nsatterl/Projects/alerta/alerta/utils/plugin.py:23]
2018-08-15 01:49:52,332 - alerta.plugins[36667]: INFO - Server plugin 'rocketchat' enabled. [in /Users/nsatterl/Projects/alerta/alerta/utils/plugin.py:31]
2018-08-15 01:49:52,332 - alerta.plugins[36667]: INFO - All server plugins enabled: reject, blackout, rocketchat [in /Users/nsatterl/Projects/alerta/alerta/utils/plugin.py:34]

An invalid Webhook URL or Auth Token can result in error messages similar to the following:
