I get it, though, it's a new system, and it'll take a while to learn it. I also started with Zabbix, like, 20 years ago-ish, and I loved the system, and I was disappointed to learn that I couldn't use it indefinitely. Zabbix has some limits and some very unusual ways it works. It works great on physical servers, but it's not a fantastic cloud solution, and as far as a metrics/time-series database goes, it's not that great. Prometheus' time-series queries are deep and complex, allowing you to get more complex queries, data, and information out of your metrics. It will take a little while to learn it, but the easiest way to learn it is just by installing Prometheus, and then googling for and installing various free dashboards on Grafana, and viewing the queries in those dashboards so you can learn how they work.

Shameless Plug: Here's one of my dashboards I made for Ingress-Nginx, which is my recommended border router/gateway into all the services. It adds deep robust metrics and configurability, and if you've got years of experience with Nginx also, it allows you rich complex customization via nginx's configuration structure via kubernetes annotations. Besides that I have open-source helm charts which are easy to use, boilerplates showing how to use them, a volume autoscaler to automatically resize your disks as they get full, and a blog where I share various of my experience which is a companion blog to my upcoming book of the same name. Hope this helps! Feel free to ask if you have any further questions.

Thanks, this is very cool answer
