      Description

        A per interface requestable event showing the network utilization.
        Defaults to every 5 seconds.

        *Event Name:* NIC IO
        || Attribute name || Description || Content type || Type || \[Value range\] or Example Value || Relational Key |
        | Interface | unique interface identifier | text | String | eth1 | (/) |
        | Read utilization | a fraction of the full utilization | percentage | float | \[0,1\] | (x) |
        | Write utilization | a fraction of the full utilization | percentage | float | \[0,1\] | (x) |
        | Read rate | read rate in bytes per second | unknown | long | 1334134 | (x) |
        | Write rate | write rate in bytes per second | unknown | long | 1324534 | (x) |

        _*Note:* Read and Write rates are probably easier to implement than utilization._
