A linter (vet) found the following bug in the code:
> daemon/metrics.go:124::error: range variable p captured by func literal (vet)
Here a variable p is used in an async fashion by goroutine, and most
probably by the time of use it is set to the last element of a range.
For example, the following code
```go
for _, c := range []string{"here ", "we ", "go"} {
go func() {
fmt.Print(c)
}()
}
```
will print `gogogo` rather than `here we go` as one would expect.
