示例1: timeGraphiteRequest
func timeGraphiteRequest(e *State, T miniprofiler.Timer, req *graphite.Request) (resp graphite.Response, err error) {
e.graphiteQueries = append(e.graphiteQueries, *req)
b, _ := json.MarshalIndent(req, "", " ")
T.StepCustomTiming("graphite", "query", string(b), func() {
key := req.CacheKey()
getFn := func() (interface{}, error) {
return e.graphiteContext.Query(req)
}
var val interface{}
val, err = e.cache.Get(key, getFn)
resp = val.(graphite.Response)
})

}示例2: Query
// Query performs a request to Graphite at the given host. host specifies
// a hostname with optional port, and may optionally begin with a scheme
// (http, https) to specify the protocol (http is the default). header is
// the headers to send.
