Thanks for the suggestion.  However I still need to have a separate script 
running vmstat as it's results are wildly inaccurate if run as "vmstat", you 
need to run "vmstat 2" to get reliable results (and the first line won't be 
the one you want).

I was thinking of having something like vmstat constantly running and 
periodically writing it's results to a file.

Another issue is that I don't want a load spike to trigger an alert.  So I 
want to have an average over say a minute "vmstat 60" (which makes it 
impossible to run vmstat from the script, reading from an output file from a 
daemon process is the only real option).
