Service for managing and receiving Alertmanager alerts on Matrix

alertmanager-matrix

Service for sending alerts from the Alertmanager webhook to a Matrix room and managing Alertmanager.

Usage

The service is configured either through command line arguments or environment variables. With the provided systemd service file (alertmanager_matrix.service), the configuration is done in /etc/default/alertmanager_matrix as follows:

ARGS=""
HOMESERVER=http://localhost:8008
USER_ID=@bot:example.com
TOKEN=<token>

See alertmanager_matrix -help for all possible arguments.

Configure Alertmanager with a webhook to this service:

receivers:
- name: matrix
  webhook_configs:
  - url: "http://localhost:4051/<room_id>"

When the -rooms option is provided the bot will join the listed rooms and only allow commands from these rooms. The service will not automatically join the room given in a webhook.

Message customization

The alert messages can be customized by providing custom templates using the -text-template and -html-template flags. The built-in default templates can be found in the documentation.

The icons and colors define the behaviour of the built-in icon and color templating functions. They can be configured by providing a YAML file using -icon-file and -color-file respectively. See the documentation for the default values.
