Issue/Introduction



When comparing Volumes in a Custom Report to values in an exported CSV they do not appear to match up.  How does NFA covert the data seen in csv exports to the data seen in Custom Reports in the GUI.

Resolution

The data in the csv file is stored in octets and the GUI will be in Kilobytes, MegaBytes or GigaBytes.

The example below explains how we convert the data.
If NFA is showing 11.33 MBytes for a conversation and the csv is showing 11876100.
The columns in the csv show data in octets, to convert it to what is shown in GUI you need to divide it by 1024 to convert to Kbytes and by (1024*1024) to convert to MBytes.

Hence here 11876100 / (1024 * 1024) = 11.325 which when rounded becomes 11.33 Mbytes.
