Notification groups describe how the messages and alarms will be delivered to users.

There are the following ways:

• Email: the message will be delilvered through the smtp relay server to the user’s email address or to a specific email address
• SMS: the message will be delilvered through the sms proxy server to the user’s phone or to a specific phone number
• Telegram: the message will be delilvered to a specific Telegram user account

The steps to create a Telegram Notification are:

1. Create a channel to Telegram and a bot

2. Configure the channel to NeMo

3. Create the Notification group

Create a channel to Telegram and a bot

Fisrt step is to create a channel. Telegram members will join to the channel to read the Telegram nofitication sent by NeMo through the bot https://telegram.org/faq_channels):

For more information about bot please visit https://core.telegram.org/bots

Second step is to create a bot to add as administrator member of the channel. Open Telegram BotFather and create the bot

/start /newbot <choose the name and the username of the bot that will be configured on NeMo –note the username must end with bot>

Add the bot to the channel.

Retrieve the chat_id of the channel:

With the NeMo shell (or any other linux machine) you need to find the chat_id related to the channel:

curl https://api.telegram.org/bot<ADD the Token here>/getUpdates?offset=0

{“ok”:true,“result”:[{“update_id”:611548852, “channel_post”:{“message_id”:2,“chat”:{“id”:-1001148557862,“title”:“Channel-test”,“type”:“channel”},“date”:1499934011,“text”:“/my_ip”,“entities”:[{“type”:“bot_command”,“offset”:0,“length”:6}]}}]}[

In this case the chat id is: -1001148557862

Now you are ready to configure telegram notification to NeMo.
