# Notification by Telegram
|
||
Sending Icinga 2 notifications via Telegram!
|
||
|
||
Special thanks to contributing [steadfasterX](https://github.com/steadfasterX) and [Tom](https://github.com/Thomas-Gelf) :-)
|
||
|
||
|
||
## Preparing
|
||
### Create your bot
|
||
|
||
<img src="img/Telegram.png" width="25%" align="right">
|
||
|
||
Obviously you need a bot to begin:
|
||
|
||
Follow the [official Telegram guide](https://core.telegram.org/bots) and do not forget to grab your bot `API TOKEN` (referred to here as `BOTTOKEN`) afterwards
|
||
|
||
### Get your chat_id(s)
|
||
|
||
You can notify a specific TG user account or throw a message to a TG group.
|
||
|
||
In order to do so you need to know the corresponding (hidden) ID also called `chat_id` (`-q TELEGRAM_CHATID`).
|
||
|
||
If you want to notify a **group/channel**:
|
||
|
||
1. Add your bot to that group/channel
|
||
1. Send with your favorite client a simple mention msg to your bot (e.g. `hi @mybot`)
|
||
1. Catch updates for your bot:
|
||
`curl https://api.telegram.org/bot<BOTTOKEN>/getUpdates`
|
||
1. Review the output, an example below:
|
||
> "message":{"message_id":91, "from":{"id":123456789, "is_bot":false,"first_name":"foo","username":"foobar","language_code":"de"}, "chat":{"id":-987654321, "title":"<GROUPNAME>","type":"group","all_members_are_administrators":true},"date":1563547428,"group_chat_created":true}}]}`
|
||
|
||
There are 2 important parts here:
|
||
- a) `"from":{"id":123456789` which is the unique user/chat_id of the user who sends a message to your bot (required to send to a notify to that person directly)
|
||
- b) `"chat":{"id":-987654321` which is the unique group/channel id of the group where the message has been sent
|
||
|
||
If you do not want to notify a group i.e. just **a direct user notification**:
|
||
|
||
1. Do the same as above, just at step 1 make a direct message to your bot instead
|
||
1. As you have done a direct message you will only get a "from" id which is all you need here
|
||
|
||
## Examples
|
||
|
||
### Testing a notification
|
||
|
||
Sending a test notification – replace the token, botname and chat id obviously.
|
||
|
||
```
|
||
sudo -u nagios ./service-by-telegram.sh -4 127.0.0.1 \
|
||
-l myhostname \
|
||
-o testingTGnotifiy \
|
||
-p <myBotname> \
|
||
-q <myGroupChatId> \
|
||
-r "<1234134325:blafasel>" \
|
||
-s CRITICAL \
|
||
-c mycomment \
|
||
-b mycommentuser \
|
||
-i https://myicingaserver/icingaweb2 \
|
||
-n maaaaaaaaaaa \
|
||
-d"$(date +%F-%T)" \
|
||
-e serviceshort \
|
||
-u fullservicename \
|
||
-D
|
||
```
