You are on the right track. Once you have a list, you save it for the next pass, say a minute later, and then if they change too much between passes, you could alert. For instance, at one minute intervals, 50% of one CPU would be 30 seconds. You might want to have an alerts sent file, or empty flag file in a flag dir, to reduce alerts every minute from the same problem proc to once per clock hour or so. You might want to send one updated list of all problem procs, not an alert per. Maybe make the list of all every minute (without time stamps and headers), and if it is the either different (comm -3 file1 file2 or just cmp) from a minute ago or both the first minute of the hour and not empty, then email it out (with time stamp and header, host name first in subject so testing and prod are not confused).

OCLOCK(1) General Commands Manual OCLOCK(1)
NAME
oclock - round X clock
SYNOPSIS
oclock [-option ... ]
DESCRIPTION
Oclock simply displays the current time on an analog display.
OPTIONS
-fg color
choose a different color for the both hands and the jewel of the clock
-bg color
choose a different color for the background.
-jewel color
choose a different color for the jewel on the clock.
-minute color
choose a different color for the minute hand of the clock.
-hour color
choose a different color for the hour hand of the clock.
-backing { WhenMapped Always NotUseful }
selects an appropriate level of backing store.
-geometry geometry
define the initial window geometry; see X(7).
-display display
specify the display to use; see X(7).
-bd color
choose a different color for the window border.
-bw width
choose a different width for the window border. As the Clock widget changes its border around quite a bit, this is most usefully
set to zero.
-shape causes the clock to use the Shape extension to create an oval window. This is the default unless the shapeWindow resource is set
to false.
-noshape
causes the clock to not reshape itself and ancestors to exactly fit the outline of the clock.
-transparent
causes the clock to consist only of the jewel, the hands, and the border.
COLORS
If you would like your clock to be viewable in color, include the following in the #ifdef COLOR section you read with xrdb:
*customization: -color
This will cause oclock to pick up the colors in the app-defaults color customization file: /usr/lib/X11/app-defaults/Clock-color. Below
are the default colors:
Clock*Background: grey
Clock*BorderColor: light blue
Clock*hour: yellow
Clock*jewel: yellow
Clock*minute: yellow
