For Axia Codex monitoring we chose Prometheus. We chose it because it was a simple standalone application and had libraries that integrated with node for recording custom stats.

https://prometheus.io/

Node.js client:

https://github.com/siimon/prom-client

Once you get it setup you can add alerting. You need to setup the alert manager program

Then add a receiver, such as an email server for sending alerts. Here is the telegram bot we used:

All 3 of those services should be installed with systemd.
