Package appstats profiles the RPC performance of Google App Engine applications.
|
|
|
|
Reference: https://developers.google.com/appengine/docs/python/tools/appstats
|
|
|
|
To use this package, change your HTTP handler functions to use this signature:
|
|
|
|
func(appengine.Context, http.ResponseWriter, *http.Request)
|
|
|
|
Register them in the usual way, wrapping them with NewHandler.
|
|
|
|
Classic App Engine packages are available at https://godoc.org/gopkg.in/mjibson/v1/appstats.
|
|
|
|
|
|
Example
|
|
|
|
This is a small example using this package.
|
|
|
|
package main
|
|
|
|
import (
|
|
"net/http"
|
|
|
|
"github.com/mjibson/appstats"
|
|
"golang.org/x/net/context"
|
|
)
|
|
|
|
func init() {
|
|
http.Handle("/", appstats.NewHandler(Main))
|
|
}
|
|
|
|
func Main(c context.Context, w http.ResponseWriter, r *http.Request) {
|
|
// do stuff with c: datastore.Get(c, key, entity)
|
|
w.Write([]byte("success"))
|
|
}
|
|
|
|
|
|
Usage
|
|
|
|
Use your app, and view the appstats interface at http://localhost:8080/_ah/stats/, or your production URL.
|
|
|
|
|
|
Configuration
|
|
|
|
Refer to the variables section of the documentation: http://godoc.org/github.com/mjibson/appstats#pkg-variables.
|
|
|
|
|
|
Routing
|
|
|
|
In general, your app.yaml will not need to change. In the case of conflicting
|
|
routes, add the following to your app.yaml:
|
|
|
|
handlers:
|
|
- url: /_ah/stats/.*
|
|
script: _go_app
|
|
|
|
|
|
TODO
|
|
|
|
Cost calculation is experimental. Currently it only includes write ops (read and small ops are TODO).
