semux-delegate-alerts

This script scans the Semux blockchain to see if the configured validator did or did not not forge a (COINBASE) block within specified time. Alerts are delivered to a webhook.

Prerequisites

This app is written in Haskell and built using stack. Just install The Haskell Tool Stack and you should be able to build and run with no issues.

Build, configure and run it like this:

./start.sh

#!/bin/sh

touch ./db_NotForgingDelegates.txt
touch ./db_LowRankDelegates.txt

SEMUX_API="https://api.semux.online/v2.1.0/" \
ALERT_RANK="95" \
ALERT_AFTER_SECS=3600 \
DELEGATE="…delegate address" \
WEBHOOK_URL="…discord webhook url" \
stack run semux-delegate-alerts

Build a binary distribution:

stack build

The binary you can find here:

.stack-work/dist/x86_64-linux/Cabal-2.4.0.1/build/semux-delegate-alerts-exe/semux-delegate-alerts-exe (replace x86_64-linux/Cabal-2.4.0.1 appropriately).

Deployment

The app checks the blockchain and exits, so it should be scheduled to run periodically, e.g.:

$ crontab -e

## edit:

*/10 * * * * /path/to/app/start.sh 2>&1 | logger -t semux-delegate-alerts

Use crontab -l to verify.
