Node sync state test

Setup

• Install nodejs. Any version above v16 should work.

  • curl -fsSL https://deb.nodesource.com/setup_17.x | sudo -E bash -
  • sudo apt update
  • sudo apt install nodejs

• Verify node version

  • node -v

• Install yarn

  • curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
  • echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
  • sudo apt update && sudo apt install yarn

• Install dependencies

  • yarn

Run the check(s)

• ./check_blocksync.js -H kusama-rpc.dwellir.com -w 10 -c 15
• ./check_rpcperformance.js -H kusama-rpc.dwellir.com -w 50 -c 200

Can also be run against an insecure websocket on a non-standard port:

• ./check_rpcperformance.js -H 127.0.0.1 -w 50 -c 200 --insecure --port 9966

The snap

See: snap-nagios-substrate.md

Use with nagios

Docs needs rewrite.

• Move the code repo to /usr/lib/nagios/plugins/
• Symlink the check_rpc.sh to /usr/lib/nagios/plugins/check_rpc.sh
• Define a command and service and add it to nagios.

Publish to npm

This guide takes you through the process: https://docs.npmjs.com/configuring-your-npm-client-with-your-organization-settings

cd node-chec
cd node-checkk 
npm login
npm config set scope dwellir.com
npm config set scope dwellir.com --global
npm publish --access public
