Overview

A tuple is like a slashport row. Each tuple contains a set of labels and data. Each label or data is a key:value pair, allowing you to name each label and each data.

For example, transmit packet counts for a network interface would have a label of ‘interface=eth0’, for example, and a data of ‘txpackets=12345’ Multiple labels are supported/encouraged, as are multiple data. Following the interface example, you could hold all metrics for a single network interface with a single Tuple: ie; 

labels: { "interface" => "eth0" }
data: { "txpackets" => 298374, "rxpackets" => 7577, "speed" => 1000 }

Labels are intended to represent attributes that will not change. Data are intended to represent attributes that can change.
