Monitor cryptonote-nodejs-pool quick and dirty checks with bash script. The script checks to node and pool health and send alert to discord channel with webhook. Ping a specific user supported.

Primary made for Kryptokrona Pools and Github but might work for others with small adjustmnents.

• Check node daemon status (kryptokrona)
• Status
• Synced
• Incoming Connections
• Outgoing Connections
• Compare block height with another node
• Verify pool health (XKR pool do not support this set XKRPOOL="YES" to skip check)
• Daemon
• Wallet
• Pool last payment
• Pool lastblockfound
• Redis server running

• 0.1 First release
• 0.2 Add some formating and loudspeaker icon
• 0.3 Moved settings to: config.cfg. Added node connections and redis-server checks. Changed parsing of json output to using "jq" instead. Added emoji codes.

For Debian/Ubuntu:

sudo apt install curl
sudo apt install bc

Clone the repository

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

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.

crontab -e

PING="<@<replace with your discord ID>>" # Discord ID - long number ,  enabled developer mode to get it Format is: <@12345678912345>
PAYMENTTIME="7200" # Seconds - 2 hours
BLOCKFOUNDTIME="3600" # Seconds - 1 hours
XKRPOOL="NO" # If using XKR orginal pool set to YES
