Ethan,
1. Are you looking for a sustained LA >= 8?
2. During the 60 minute period, are you looking at a harmonic mean for
the time period, or an arithmetic mean?
3. Do you account for standard deviation?

Subject: A Challenge
This is just for fun, I have a solution but wondering what others would
do. I will post mine later.
Task:
Monitor load average on a unix host.
Requirements:
* Notify me via email when load exceeds 8 for more than 60 minutes.
* After initial alert do not alert me again for at least 2 hours unless
the load falls below 8 before the 2 hours expires.
* Log the load to a file for historical purposes.
* Alert me when the load falls back below 8.
Challenge:
Can you come up with a solution to this problem using existing
scripts/utilities (home grown or otherwise)? Ideally lines/$$ required
to implement the better. Just wondering what others might do.
