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?
I was looking at loki+grafana. is prometheus a replacement for loki in this setup and is it preferred?
No, they serve different purposes. Loki is for logs, Prometheus is for metrics. Grafana helps to visualize data from both.
