<br>
On a related note, these values represent time points where a device is on-line
(hence one; if it was off line, the value would be zero). I would like to
compute availability by computing every 24 hours the number of points that are
1 over the total number (which should be 12). Any suggestions on how to do
that? <o:p></o:p></span></font></p>
