System monitoring can't be done with New Relic, so what should we use?

[geoidesic]

Is there a recommendation for monitoring system events? My initial plan was to use New Relic but apparently that's not supported: https://frankenphp.dev/docs/known-issues/#unsupported-php-extensions

What is the recommendation?

My goal is to be able to see:

• CPU / memory usage graphs
• Requests per second graphs
• Error notifications to something like Slack

We expose Prometheus metrics and structured log. You can collect them with Prometheus, an ELK stack, DataDog and many other solutions.
