CPU Watcher 0.7
CPU Watcher is a simple tool to monitor CPU usage,
free memory and network traffic.
It works by launching its own idling task (called "Uuno")
at priority -127. Task's execution time is measured and
the system load is determined, based on how much time
"Uuno" got during a time period (which is 1 second).
There are actually two methods to measure CPU load. Default
mode uses busy looping. Optional "simple" mode doesn't
busy loop but it may not be as accurate. Screen's titlebar
shows "B" for the busy looping method, and "S" for the
simpler method.
Running both CPU Watcher and CPUClock.docky at the same time
may not be reliable.
Features:
- shows the last 5 minutes of CPU usage (green graph)
- shows also the percentage of free
* virtual memory (blue graph)
* video memory (light blue graph)
- shows also network traffic (activated with 'n' key)
* upload speed (upper, red graph)
* download speed (lower, green graph)
* Current Kilobyte values are shown in Screen's titlebar
The graphs show current / peak * 100% value.
- supported icon tooltypes:
cpu: cpu graph ON/OFF.
vmem: virtual memory graph ON/OFF.
gmem: gfx/video memory graph ON/OFF.
grid: grid ON/OFF.
solid: solid drawing ON/OFF.
dragbar: window dragbar ON/OFF.
resize: size gadget ON/OFF.
xpos: window X position.
ypos: window Y position.
simple: use "simple" method to measure CPU load.
opaqueness: values between [20, 255] adjust window transparency.
bgcol: window background color.
gridcol: grid color.
cpucol: cpu graph color.
vmemcol: virtual memory graph color.
gmemcol: gfx memory graph color.
ulcol: upload graph color.
dlcol: download graph color.
- keyboard commands:
c - cpu graph ON/OFF.
m - toggle between CPU measuring modes, "busy" and "simple".
v - virtual memory graph ON/OFF.
x - gfx/video memory graph ON/OFF.
g - grid ON/OFF.
s - solid drawing ON/OFF. No effect on network graphs.
d - dragbar ON/OFF.
n - network graphs ON/OFF.
q - quit program.
