hi.

i'm uses prtg 8

PRTG Collecting snmp data...

I would like to know how it was calculated and bps byte.

                                                Input(Volume)    Input(Speed)
07/21/2014 00:00:00 - 01:00:00	
   59,230 GByte	133 gbit/s	50,509 GByte	114 gbit/s	0 %	100 %
07/21/2014 01:00:00 - 02:00:00	
   39,097 GByte	93 gbit/s	35,867 GByte	86 gbit/s	0 %	100 %

Dear user

Please allow me to ask you to clarify your question. What exactly do you want to know about SNMP traffic data?

Hi there

When after collecting the data bandwidth snmp, is expressed in bits per second (bps).

However, transformation is possible in byte how to express.

I want to know how they will be calculated when you want to convert to a byte from bps at this time.

Dear user

To convert from bit to byte, please divide by 8.

However we use the prefix "kilo" differently. When uses as prefix for bit, we evaluate 1 k = 1000. In conjunction with byte, we take 1 K = 1024.

The same applies for the Mega and Giga prefix.

I appreciate the answer.

Please look at the contents of the first question.

Is the monitoring of data traffic.

Time: 07/21/201400: 00:00 - 01:00:00 Input: 59,230 GByte133 gbit / s Output: 50,509 GByte114 gbit / s

If you convert to 59,230 Byte, or 133 gbit / s?

Dear

PRTG historic Data Report

Date Time Input (volume) Input (speed) Output (volume) Output (speed)

07/22/2014 7,743 GByte 128 gbit/s 6,505 GByte 108 gbit/s

8bit = 1Byte 1024 Byte = 1 Kbyte

But... PRTG differ Report 7,743 Gbyte = 8,314,000,000,000 Byte => 66,512,000,000,000 bit

Input (Speed) 128 gbit/s ????

Dear user

In this case, it looks like that either "G" uses the 1000 prefix or "g" the 1024. I asked a developer, but since PRTG is constantly developed further, we cannot look into the source code of PRTG 8 any more.

It could be a bug, which however is fixed with the current PRTG 14 version.
