delta calculation , Net.Interface.BytesIn(*)
-
HI,
I created DCI "Net.Interface.BytesIn(*)",* is the index of interface,and selected "Delta value(average per second)".I use the method "Session.queryParameter()" (Java API version 1.1.6),the result returned is the total number of bytes-in ,not delta value average per second ,I've also viewed the origin data in database and it is exactly delta value per second,why?? -
Hi!
Because delta calculation is done by server after data obtained from node as part of DCI processing. When you do queryParameter call, it just reads raw value from end node - it is not related to any DCI. You either have to do delta calculation by yourself or use another API call to get last values of particular DCI.
Best regards,
