01 · Icons

  • Want to see at a glance how your CPU, disk, memory and network are doing?
  • Without opening Task Manager or keeping a window on screen?

Then with tetramon you can:

  • Four icons in the Windows tray, each with its history: CPU, disk (read and write), memory (percentage as a number) and network (download and upload).
  • Memory changes colour by level (from 50, 75 and 90 %, configurable) and has an optional level bar.
  • Hover over them and the tooltip gives the details: usage per disk, speeds, free memory, network interface.
  • Show only the ones you want, each with its own refresh (0.5 to 10 s), colours and border.
Icons

02 · Graphs

  • Need to see what happened over the last few minutes, not just now?

Then with tetramon you can:

  • Click the CPU, disk or network icon to open its floating graph: translucent, no title bar, out of the taskbar.
  • Bars or smoothed lines with fill; automatic scale and the exact value under the mouse, with how long ago it was.
  • Disk as speed (KB/s, MB/s) or activity (%): click the graph to switch.
  • Snapping between graphs and to the screen edges to line them up and match their size; Always on top or pinned, which lets clicks go through to whatever is underneath.
Graphs

03 · Per core

  • Want to know whether a program is maxing out a single core?

Then with tetramon you can:

  • The CPU graph can show a tile per thread: performance cores in blue, efficiency cores in green.
  • The tiles fill the whole window even with an odd number of threads and rearrange when you resize.
Per core
04

Settings

  • One dialog with tabs (CPU, Disk, Memory, Network, General) and live previews of every icon and graph.
  • Changes show at once; each tab is saved on its own and closing without saving puts it back.
  • It opens where and on the tab you left it.
  • Start with Windows, for your user or for everyone.
  • In English and Spanish: it follows Windows or the language you choose.

05

Hardware

  • The Detected hardware block tells you what's inside: processor (performance and efficiency cores, threads, cache), memory modules per slot (size, type, speed, maker) and disks with their free space.

06

Updates

  • A single half-megabyte .exe, no installer and no dependencies: copy it anywhere and run it.
  • It tells you when there's a new version; one click downloads it, checks its fingerprint and restarts already updated. It never updates by itself.
