hi,
i'm trying to do something very basic, but cant seem to find any info in the forums about it.
i've got a bunch of HP printers i've set up a UDP to get the total number of pages printed from the printer. i'm keeping historical data on this OID. and i'd like a simple transformation of the data. I'd like to get todays print totals.. and this month's print totals... should be fairly simple but i cant seem to find any info on how to do this.
basically:
HPPrintTotalToday=HPPrintTotal.currentvalue-HPPrintTotal.ValueYesterday
and
HPPrintTotalMonth=HPPrintTotal.currentValue-HPPrintTotal.ValueFirstDayofCurrentMonth
Any suggestions would be greatly appreciated.
