Terminal tea is piping hot
Perfmon – Consolidate your favorite CLI monitoring tools into a single TUI
Fans love the tidy dashboard, skeptics yell “Just use tmux,” and a name fight erupts
TLDR: Perfmon is a new terminal app that unites several system monitors into one tidy, tabbed dashboard. The community likes the look but is split: some want proof it beats existing tools like tmux and bottom, and others say the “perfmon” name will confuse Windows users.
Perfmon promises a clean, customizable dashboard for your computer’s vital signs—think tabs for CPU, memory, and network, plus cute live charts—in a single text window. The crowd’s first reaction? “It looks slick.” But the honeymoon ended fast as power users crash‑landed with questions. One camp wants receipts: Peter asked how it stacks up to “bottom,” a popular terminal dashboard. Another camp went straight to the jugular: why not just use tmux, the tab/split-screen manager nerds already adore? If Perfmon simply corrals tools like top and netstat, does it do anything new beyond style points?
