Question marks used as values in the output examples are generated when a division by zero is made. It represents data that is not available. The numbers in the columns are calculated, for example, by dividing KB by number of blocks read. When there are no blocks read, KB is divided by zero. A question mark does not mean there is an error, but indicates that there is no information to report for this time period.
