Avalanche | Telegram BOT

Telegram

• Creating Telegram Bot

  • Access Telegram ➜ .

    • Search: BotFather.

    • Click “Start” to activate the BotFather bot.

    • Choose the command /newbot and Click.

    • Choose a name for your bot. Example: fujitestavalanche.

    • Choose a username for your bot. Example: fujitestavalanche_bot.

      You will receive a message with a link to your bot t.me/nameyourbot.
      After giving your bot username, your TOKEN will be available as noted below:
      

      
      Note: Copy the alphanumeric code of your TOKEN , as we will use it later!
      Note that TOKEN is the code right after “HTTP API:”.

    • Start communicating with our bot by entering the name of your bot in the search tab and choose it. Example: fujitestavalanche.

    • Click on the “Start” button and you will be subscribed to your bot.

    • Type “/ start”.

• Obtain the CHAT ID (chat ID of the bot):

  Two parameters: TOKEN and CHAT ID — are mandatory for creating the script for the real-time alert system of your Avalanche Network node.
  We must remember that we already have a TOKEN.

  • Access the VM/VPS that supports your Avalanche network node.

    First install the “jq” utility, set your TOKEN variable and, using the curl command.

  • Obtain your chat ID as shown below:
    ​​​​​​​​sudo apt-get install jq -y
    ​​​​
    ​​​​​​​​TOKEN=<insert your token>
    ​​​​
    ​​​​​​​​curl -s https://api.telegram.org/bot$TOKEN/getUpdates | jq .result[0].message.chat.id
    

    Copy & Paste — each line of code and “Enter”, successively, line by line, until the last command line, in the SSH Web session of your VPS.

    If CHAT_ID is not available, it's okay to type “/ start” three to four times, in the same way, re-enter the command line curl -s https://api.telegram.org/bot$TOKEN/getUpdates | jq .result [0] .message.chat.id until the CHAT_ID code appears.

Telegram | Avalanchego Monitoring Script:

The Avalanchego monitoring script, which includes the real-time alert system of your Avalanche network node, performs three fundamental checks every minute, as shown below:

• If the avalanche process is working;
• If the avalanche process is healthy; and
• CPU usage (the default limit is 40%).

Our Avalanchego monitoring script has two mandatory and two optional parameters, which are:

• Mandatory are TOKEN and CHAT ID.
• Optional are CPU and IP limit.

• Avalanchego Monitoring Script Installation:

  ​​​​cd
  
  ​​​​sudo apt-get install git
  
  ​​​​git clone https://github.com/burcusan/telegram-monitor-scripts.git
  ​​​​
  ​​​​cd telegram-monitor-scripts
  
  ​​​​./install_avax_monitor.sh -t insert_here_the_code_of_your_token -c insert_here_the_code_of_your_token_CHAT_ID
  
  ​​​​sed -i 's/health.getLiveness/health.health/g' check_avalanchego_status.sh
  

  Copy & Paste — each line of code and “Enter”, successively, line by line, until the last command line, in the SSH Web session of your VPS.

• Test to verify that your script is working correctly:

  ​​​​./check_avalanchego_status.sh > check_avalanchego_status.logcat check_avalanchego_status.log
  

  ​​​​./check_avalanchego_status.sh test
  

  In this script we are using the default parameters for a 40% CPU limit and API call IP is 127.0.0.1.

  If the script has been installed correctly, the test message will be sent to your Telegram bot as noted below:

  ​​​​Mon Sep 26 07:52:31 UTC 2022 | [TEST] [TEST] | Avalanchego Fuji Node TEST Message...!!!
  

  • Check the test message received by your Telegram bot:
    

Canceling Alert Messages:

If you no longer want to receive alerts via your Telegram bot, just remove a line from the script in your crontab file. Edit it via crontab -e and remove or comment (put # at the beginning of the line) the related line as shown below:

#* * * * * /home/username/telegram-monitor-scripts/check_avalanchego_status.sh > /home/username/telegram-monitor-scripts/check_avalanchego_status.log 2>&1
