1) Downloading & Installing

Clone the repository

git clone https://github.com/glen487/PMQaD
cd PMQaD
sudo chmod +x pmqad.bash
sed -i -e 's/\r$//' pmqad.bash

2) Configure

Edit the config.cfg and adjust to your needs.

POOL - hostname.domain.tld
NODE - hostname.domain.tld
WEBHOOK_URL - URL Webhook to discord channel
PING - To ping a specific user add Discord user id (long one @1234566789123456) enabled developer mode under advanced settings.
Adjust the PAYMENTTIME and BLOCKFOUNDTIME time depending on your pools need. Depends on numbers of miners, pool and total network hashrate.
XKRPOOL - YES if pool is based on orginal Kryptokrona Pool to not support pool health checks.
Script expected to be running local on the pool and checks pool node via local host.
Pool API is checked via pool hostname and expected that HTTPS is used and API is served via https:///api/stats. Change to HTTP and localhost:port if needed.

3) Cronjob

crontab -e

# Add to run every 15 min
15 * * * * ./pmqad.bash

Sample config.cfg

POOL="floki.kryptokrona.se" # Pool hostname
NODE="gota.kryptokrona.se" # Node hostname to compare height
WEBHOOK_URL="https://discord.com/api/webhooks/<replace with your webbhook address>" # URL for channel discord
PING="<@<replace with your discord ID>>" # Discord ID - long number ,  enabled developer mode to get it Format is: <@12345678912345>
