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/telegram

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

Add telegram 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 = ['telegram']
TELEGRAM_TOKEN = ''  # default="not set"
TELEGRAM_CHAT_ID = ''  # default="not set"
TELEGRAM_TEMPLATE = '' # default will use hardcoded one (can be a filename to template file)
TELEGRAM_PROXY = '' # default="not set", URL must start from http://, socks5 not supported
TELEGRAM_PROXY_USERNAME = '' # default="not set"
TELEGRAM_PROXY_PASSWORD = '' # default="not set"

Create a new Telegram Bot using a Telegram client.

See https://core.telegram.org/bots#creating-a-new-bot

To ack, close or blackout an alert from the Telegram client set the webhook URL to your Alerta API Telegram endpoint (must be HTTPS):

TELEGRAM_WEBHOOK_URL = 'https://alerta.example.com/webhooks/telegram'
BLACKOUT_DURATION = 86400   # default=3600 ie. 1 hour

To enable/disable sound on notifications(disable_notification) use TELEGRAM_SOUND_NOTIFICATION_SEVERITY:

# Only severities 'security', 'critical' and 'major' have disable_notification=False
# all other severities have disable_notification=True
TELEGRAM_SOUND_NOTIFICATION_SEVERITY = ['security', 'critical', 'major']

If TELEGRAM_SOUND_NOTIFICATION_SEVERITY is unset then all telegram notifications have disable_notification=False

Templating

There can be defined template to send data to telegram it have to be defined in TELEGRAM_TEMPLATE. TELEGRAM_TEMPLATE can be a filename pointing to Jinja2 template file. Template have to be writen in Jinja2 Alert data will be passed to it as context. So you can modify tg message as you wish. Example can be found in Explorer
