cmd/scollector: Covert gauges to counters for os.cpu

No description provided.

these variable names are not descriptive enough to indicate what is going on here.

Suggestions?

[captncraig]

i,ts,t,v -> total,lastTimestamp, time, value

[kylebrandt]

oldTs and ts? i to total?

[kylebrandt]

Sounds good, thanks

[captncraig]

How about

type tsIntegrator struct{
   data map[string]struct{
      total floats64
      lastTime
   }
   sync.Mutex
}

?

then you can do cpuIntegrator.Add(key, now, val) and cpuIntegrator.Total(key). Hide all of the mutexing and map stuff inside the integrator.

I was thinking there might be use cases where you don't want to use it in
the map, so this would make it more reusable

if you make the integrator here and pass it into c_cisco_cpu, you may not need the map or mutex at all.
