As in, when I watched YouTube tutorials, I often see YouTubers have a small widget on their desktop giving them an overview of their ram usage, security level, etc. What apps do you all use to track this?

One thing about using Prometheus alerting is that it’s one less link in the chain that can break, and you can also keep your alerting configs in source control. So it’s a little less “click-ops,” but easier to reproduce if you need to rebuild it at a later date.

When you have several Prometheus instances (HA or in different datacenters), setting up separate AlertManagers for each of them is a good idea. But as OP is only beginning his journey to monitoring, I guess he will be setting up a single server with both Prometheus and Grafana on it. In this scenario a separate AlertManager doesn't add reliability, but adds complexity.

As for source control, you can write a simple script using Grafana API to export alert rules (and dashboards as well) and push them to git. Not ideal, sure, but it will work.

Anyway, it's never too late to go further and add AlertManager, Loki, Mimir and whatever else. But to flatten the learning curve I'd recommend starting with Grafana alerts that are much more user-friendly.
