Functions

func AddTickerFunc

func AddTickerFunc(f TickerFunc)

AddTickerFunc adds a new function callback to the list of metrics TickerFuncs that get called each minute.

func Push

func Push(history *list.List, ev expvar.Var) string

Push adds the metric to the end of the list and returns a comma separated string of the previous 61 entries. We return 61 instead of 60 (an hour) because the chart on the client tracks deltas between these values - there is nothing to compare the first value against.

Types

type TickerFunc

type TickerFunc func()

TickerFunc is the function signature accepted by AddTickerFunc, will be called once per minute.
