git clone https://github.com/marty1885/monitor-tgbot
cd monitor-tgbot
mkdir build
cd build
cmake ..
make

Before using the bot. A few configuations have to be provided by the user. First, you'll need to provide the token that the bot is attached to. If you don't have one, follow Telegram's guide to create one. With your token, you'll need to put the token into a confuration file. The bot will attempt to load ~/.config/monitor-tgbot/monitorbot_config.lua as it's configuration. You may also make one yourself then ask the bot to load it using the -f parameter.

c.bot.token = "132648513:haeohNLANDKban21ja8coanLANlnca64530" -- this is a made up token

Then you'll need to generate a password for the bot. The password authenticaes an account to be added to the list of brodcat. Then you will be notified when services goes down.

❯ cd /path/to/monitor-tgbot/build
❯ ./monitor-tgbot --gen-password
Password:

SHA256:yrmU1VSZtYkC6Oli:a1d9f71497f779b467d4b9b3519b9de06a87725e3487917a89c97bbcdb90517e

Don't worry. I generated the hash by a random monkey pressing randomly on my keyboard. Now put the password into the confuguration file.

c.bot.password = "SHA256:yrmU1VSZtYkC6Oli:a1d9f71497f779b467d4b9b3519b9de06a87725e3487917a89c97bbcdb90517e"

Then just specsify which services you want the bot monitor and how often the bot should check.

c.monitor.services = {"tor", "sshd"}
c.monitor.interval = 300

There are other configurations you can do or overwrite the values via command line. See monitorbot_config.lua and ./monitor-tgbot for more information

Now it's time to launch the bot.

❯ ./monitor-tgbot 

Go to your bot in Telegram. Type in your password. And the bot will confirm that you are added to the list of users.

ping - Pong!
monitored_services - Replies a list of monitored service
ack - acknowledges that I know the service is down. Don't bother me again
