Minter node monitoring tool

A python service sending alerts via Telegram bot in case of either your node is offline or has missed a block.

Prerequisites

Your own Telegram bot with api token (create via @BotFather bot)
Your own server with Python 3+, pip, virtualenv installed

Service setup

Execute line by line in server terminal:

useradd -m minter-monitoring
chown -R minter-monitoring:minter-monitoring /home/minter-monitoring/
cd /home/minter-monitoring/
virtualenv venv
source venv/bin/activate
pip install python-telegram-bot==12.0.0b1
pip install git+https://github.com/U-node/minter-sdk git+https://github.com/Minterious/minter-monitoring

Create /home/minter-monitoring/config.json file based on example. You should customize the following parameters:

minter_api_url - API url of a synced mainnet Minter node
minter_nodes_pub_keys - public keys of nodes to monitor
node_pubkey - mapping public key -> node name
telegram_bot_token - Telegram Bot API access token
monitoring_auth_key - can be any secret string to use as an alerts subscription key for your Telegram bot

Create service file like /etc/systemd/system/minter-monitoring.service with the following content:

[Unit]
After=network.target

[Service]
Type=simple
User=minter-monitoring 
ExecStart=/home/minter-monitoring/venv/bin/python /home/minter-monitoring/venv/lib/python3.6/site-packages/mintermonitoring/main.py /home/minter-monitoring/config.json 
Restart=always
RestartSec=1

[Install]
WantedBy=multi-user.target
Alias=minter-monitoring.service

Usage

After running the service send /start {monitoring_auth_key} message to bot to authorize yourself.
At this point you are done and will receive alerts via Telegram bot in case of either your node is offline or has missed a block
