Masternode Health Server

This script is designed for collecting server & DeFiChain node information of your system and send them to the DeFiChain Masternode Health API.

For a closed look in it's functionality there's a detailled documentation.

Installation

• Install pip3 (pip from python v3. Some operating systems just name it pip)
• Run pip3 install masternode-health

Make sure you set rpcuser=xxx and rpcpassword=xxx in your defi.conf You can choose the username and password by yourself.

Hint: restart your node after updating your defi.conf

Upgrade to the current release

pip3 install --upgrade masternode-health

Create API key

This scripts needs a DeFiChain Masternode Health API key. Take a look at the documentation.

tl;dr:

Open up a new tab in your browser, paste in that URL

https://api.defichain-masternode-health.com/setup/api_key

You'll get something like this:

{"message":"API key generated","api_key":"537e13a8-d027-45db-8f51-92b5219b203f"}

The part after "api_key":" (537e13a8-d027-45db-8f51-92b5219b203f) is your API key. Copy it (without "}), store it in a safe place like your password manager and close that browser tab because you don't need it anymore.

Usage

Prerequisites

You can either run masternode-health by calling it with it's relative path in your user's directory:

~/.local/bin/masternode-health --help

OR you can create a symlink for making the masternode-health command accessible from anywhere on your system. The following command requires sudo rights.

sudo ln -sf ~/.local/bin/masternode-health /usr/local/bin/masternode-health

Running Masternode Health

To keep it simple, the following examples do not contain the relative path like described above.

$ masternode-health --help
usage: masternode-health [-h] [--max-block-seconds MAX_BLOCK_SECONDS] [--rpchost RPCHOST] [--verbose] [--report] [--defi-path DEFI_PATH] [--defi-conf DEFI_CONF] [--api-key API_KEY] [--version]

DefiChain Masternode Monitor

optional arguments:
  -h, --help            show this help message and exit
  --max-block-seconds MAX_BLOCK_SECONDS
                        Alert if node did not try to calculate hash within max-block-seconds (default: 30 seconds)
  --rpchost RPCHOST     RPC host (default: http://localhost:8554)
  --verbose             Prints stats to stdout
  --report              Force sending report when using in combination with --verbose
  --defi-path DEFI_PATH
                        Path to your .defi folder. Default: ~/.defi
  --defi-conf DEFI_CONF
                        Path to your defi.conf. Default: ~/.defi/defi.conf
  --api-key API_KEY     API Key
  --version             Returns masternode-health version

You can manually run it with

$ masternode-health --verbose --report --api-key=your-api-key

Please don't forget to replace the following parts with your own:

• your-api-key: make an educated guess ;)

Run automatically with a cron job

Add calling Masternode Health into your crontab to check every 10 minutes.

First, open up a text editor to edit your crontab with:

crontab -e

Add the following line to run it every 10 minutes: (Masternode Health won't accept any higher frequency than every 10 minutes)

*/10 * * * * ~/.local/bin/masternode-health --api-key=your-api-key

Warning: The API allows only 1 call to each endpoint every 300 seconds. Don't let the cron run more often than every 5 minutes!

Please don't forget to replace the following parts with your own:

• your-api-key: make an educated guess ;)

Verbose

To take a look at the collected data, you can use the --verbose argument. With this argument, no data is sent to the API. To force sending the data and viewing the verbose output use the --report argument in parallel.
