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>

http://docs.observium.org/alerting_transports/#telegram

Add the bot to the channel.

Retrieving 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.

1. On Admim tab, select Configuration/Notification Groups/Telegram Channels

2. Click Add Channel

3. insert the Name of the channel that will be used on NeMo, the description, the chat identifier and the Bot Token

4. Create a new notification group (Configuration/Notification Groups→Add Group) and save changes

5. Select the notification group and click Edit Group button

6.

4. select the tab Members and select Telegram as method

5. Select the Telegram channel

Testing the notification group

The administrator of the telegram group must add users that want to receive notification in the group, then select the notification group and click Send Test button

Congratulations, you have created your Telegram Notification group!
