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 use Telegraf + InfluxDB + Grafana for monitoring my home network and systems. Grafana has a learning curve for building panels and dashboards, but is incredibly flexible. I use it for more than server performance. I have a dual-monitor “kiosk” (old Mac mini) in my office displaying two Grafana dashboards. These are:

    Network/Power/Storage showing:

    • firewall block events & sources for last 12 hrs (from pfSense via Elasticsearch),
    • current UPS statuses and power usage for last 12 hrs (Telegraf apcupsd plugin -> InfluxDB),
    • WAN traffic for last 12 hrs ( from pfSense via Telegraf -> InfluxDB),
    • current DHCP clients (custom Python script -> MySQL), and
    • current drive and RAID pool health (custom Python scripts -> MySQL)

    Server sensors and performance showing:

    • current status of important cron jobs (using Healthchecks -> Prometheus),
    • current server CPU usage and temps, and memory usage (Telegraf -> InfluxDB)
    • server host CPU usage and temps, and memory usage for last 3 hrs (Telegraf -> InfluxDB)
    • Proxmox VM CPU and memory usage for last 3 hrs (Proxmox -> InfluxDB)
    • Docker container CPU and memory usage for last 3 hrs (Telegraf Docker plugin -> InfluxDB)

    Netdata works really well for system performance for Linux and can be installed from the default repositories of major distributions.
