Why not an array and a enum for status? Seems better for me

I'm not totally sure what you mean by this.
Do you mean enum as in?
type tcpStatus string
const (
closeWait tcpStatus = "CLOSE_WAIT"
closed tcpStatus = "CLOSED"
...
)Also I think a map should outperform an array here since we need to iterate through potentially 100s of connections to record the counts. Using an array would require O(n^2)?

I mean an enum as in:
type tcpStatus int
const (
closeWait tcpStatus = iota
closed tcpStatus
...
)

You may need a switch for the status. Not 100% sure so your call

Oh okay yea - ofc 🤦♂️
We would need a switch to convert strings to indexes, so I suspect performance would be pretty similar either way. Annoyingly gopsutil actually converts these from ints to strings before returning the values 😞
If you don't feel too strongly about this I will probably leave it as is. This has the arguably useful propery that if we ever receive an unexpected status value, it will get added to the map.
