Sum o values

[akbar415]

Hi.
I have a map that show the network traffic between router.
I can set the network traffic to show in map the just adding the item key on label {router-01:ifInOctets[Serial0/1/0].last}

But how can I show the sum of two key in the label on a map?
Sample
Item A: {router-01:ifInOctets[Serial0/1/0].last}
Item B: {router-01:ifInOctets[Serial0/1/0].last}
I want to show the sum of Item A and B.

How can I do that?


Sorry for the bad english
