dciId = 2531;
threshold = 500 * 1000 * 1000;

t = localtime();
t->hour = 0;
t->min = 0;
t->sec = 0;
endTime = mktime(t);

if (t->mon >= 2) {
  t->mon = t->mon - 1;
}
else
{
  t->mon = 12;
  t->year = t->year - 1;
}
startTime = mktime(t);

a = GetDCIValues($node, dciId, startTime, endTime);

HighCnt = 0;

return HighCnt / Cnt;

Here's an example script that grabs all values for a DCI for last month. You can put this in a script DCI that is being collected by cron schedule on the first day of each month.

Once you nave array with values, you can do various calculations with them. If you want to do calculations that involve big numbers, e.g. calculating average value, initialize variable like that:

TotalCounter = 0L;

This will use INT64 for this variable.
