Question

I would like to trigger the accounting interim-update on freeradius and then exec a script to performe a calculation about the total data volume usage related a specific user. Could anyone help me with some example?

Sure that's pretty simple

Put the contents of the accounting block below into raddb/sites-available/default and modify as necessary.

accounting {
    if (Acct-Status-Type == 'Interim-Update') {
        update request {
            Tmp-Integer-0 := `/path/to/my/script.sh %{Acct-Input-Octets} %{Acct-Output-Octets} %{Acct-Session-Time}`
        }         
    }
}
