The interface status page status_interfaces.php is supposed to print a section called "Total Interrupts" at the bottom of each physical interface, but it does not.

The handling of that data is broken in a few ways:

• The result is unset before it tries to display the text, which means it will never show up on the page.
• Even if the above is corrected, the results are wrong for interfaces with multiple queues.
• The way the statistics are obtained is inefficient (running vmstat -i separately for every interface), it should gather the stats just once using something closer to vmstat -i --libxo=json at the top and then parse/sum the data from the interpreted result. This will be much more efficient and accurate than relying on the current methods.
