Polygon Monitor

This is a simple typescript application to enable monitoring of a Polygon validator node from Tessellated Geometry.

It checks:

• The amount of ETH on your signing key
• Heimdall block height vs an external API
• Bor block heigh vs an external API
• Your signature is in the latest Heimdall Blocks

In the future, it should also check:

• Your signature is in the latest Bor Blocks

If any condition fails, it will send you a page via Pager Duty's API.

Setup

• Install npm (or yarn if that's your thing).
• Run npm i to install dependencies.
• Retrieve your pager duty API token, pager duty service identifier, and pager duty email from PagerDuty
• Modify global variables in src/monitor.ts for the specifics of your setup.
• Run ./start.sh.

You'll likely need to do a bit of light customization to make this infrastructure suite your exact needs. PRs to generalize the software or extend functionality are welcome. In particular, it would be cool to provide a customizatble remote API.

Feel free to drop us a line on Keybase or at hello@tessellatedgeometry.com if you need help.

Daemon

A service definition is included. You can modify and deploy the deamon with:

mv polygon-monitor.service /etc/systemd/system/
