Cosmos Monitor

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

It checks:

• If the local node is out of sync with api.cosmos.networ
• If your validator's precommit is missing from the most recent block

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.

Daemon

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

mv cosmos-monitor.service /etc/systemd/system/
systemctl enable cosmos-monitor
systemctl start cosmos-monitor
