siteping

Siteping is a tiny bash script for monitoring hosts, it notifies you when a host is unavailable. The notification is using the Telegram-Bot API. Before you can use it, create your personal Telegam-Bot token.

More information: https://core.telegram.org/bots

Installation

  1. Install it on your Raspberry PI or your preferred Linux operating system.
  2. Copy the scripts into YOUR_HOME_DIR (or elsewhere) be sure that the directory is writable.
  3. Grant execution rights to both scripts
   sudo chmod 755 siteping.sh
   sudo chmod 755 tpush.sh

  1. Edit tpush.sh and replace YOUR_TOKEN with your Telegram-Bot token and the chatId with your chatId.
    a) to get the chatId create a group and add the Telegram-BOT to your group
    b) post a message in your group
    c) open https://api.telegram.org/bot<YOUR_TOKEN>/getUpdates in a browser
    d) copy the chat:id from the json respons.
    If you get an empty result, add the bot again to the group.

  2. Edit siteping.sh and add new host names or change the existing host names for your needs. Don't remove the default counter value 1 at the end of each host name. If you do not want to receive a notification every hour, change the default counter value to 5

  3. Add siteping.sh as cronjob to run as background process. Edit the crontab

   sudo crontab -e
  1. Add these lines and save your crontab
   @reboot /YOUR_HOME_DIR/siteping.sh &
   0 * * * *  /YOUR_HOME_DIR/siteping.sh &
  1. Test the notification script, go to your home dir an run the tpush.sh script
   cd /YOUR_HOME_DIR
   ./tpush.sh "hello world"
  1. If your Telegram app does not receive your message, check the above steps again.
