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._
