**skim**
skim records the sizes of packets passing through an interface so you
can monitor network usage. it sorts this information by transport type,
tcp/udp, and port number.
skim exposes an interface for retrieving statistics on tcp port 6666.
first send a u32, big endian, and then json data with the ports you
want. the json should look like this:
`{ "tcp": [80, 443], "udp": [53] }`
you'll get a response back in a similar format. the first four bytes
will be the length of the response, big endian, and then the json data.
the data'll look like this:
```json
{
"tcp":[{"port":80,"tx":0,"rx":0},{"port":443,"tx":56260,"rx":4195}],
"udp":[{"port":53,"tx":210,"rx":173}]
}
```
skim records network traffic assuming the host system is acting as a server.
