Wicked.

Pity vmstat doesn’t do EPOCH like dstat does. The x scale doesn’t work great for knowing exactly what’s happening.

A few problems, the filter script and plot script doesn’t cut and paste well (smart quotes mainly). would be great to get them into a pre, or downloadable file.

When running under Ubuntu 7.10 I get the following errors for reference

./cpuchart.plt

set ticscale 1 0.5
^
“./cpuchart.plt”, line 90: warning: Deprecated syntax – please use ’set tics scale’ keyword

title “User”
^
“./cpuchart.plt”, line 137: invalid command

Now all we need to know is how to save it directly as a png. Your last script seems to indicate this?
