Yes.

Load is the number of processes in the run queue averaged over the time
period. It's an arbitrary but surprisingly useful metric.

The plugin checks all three values. As I understand it, it would raise
a warning if 1 minute load was over 15 or 5 minute load was over 10 or
15 minute load was over 5.

The load was obviously increasing at the time you checked it (the 1
minute
average is double the 15 minute average) but other than that it looks
OK.
The defaults are nicely judged - I'd generally start worrying if the 15
minute
average was hitting 5 or either of the others was hitting double
figures.
