> The problems is that I get WARN when the load is less than that:
> WARNING - load average: 1.77, 1.94, 3.04
> WARNING - load average: 2.11, 2.23, 3.45
> WARNING - load average: 1.90, 3.59, 4.34
> WARNING - load average: 5.65, 5.05, 4.86

You configured it to warn when the 15-minute average is 3.00, and
in your above four examples, the 15-minute averages are all > 3.00.
It is working like you configured it to.

The plugin's output is 1-minute, 5-minute, and 15-minute average.
