Server Stats

Server Stats provides a structure and Echo handler for tracking server statistics, such as when the server started, number of requests, and the count of various status codes. Here is an example of using this in an Echo application.

httpServer = echo.New()

/*
 * Server stats middleware
 */
serverStats := serverstats.NewServerStats(nil)
httpServer.Use(serverStats.Middleware)

httpServer.GET("/serverstats", serverStats.Handler)

The ServerStats object satifies the IServerStats interface, allowing developers to implement their own statistics. It also provides the ability to provide a callback method to add custom stats per application. This is done by passing a method to the NewServerStats constructor method. Inside this method you can work with a map called CustomStats. This is a map of string keys with interfaces for values.

httpServer = echo.New()

/*
 * Server stats middleware
 */
serverStats := serverstats.NewServerStats(func(ctx echo.Context, serverStats *ServerStats) {
	var ok bool
	var value int

	if _, ok = serverStats.CustomStats["someCounter"]; !ok {
		serverStats.CustomStats["someCounter"] = 0;
	}

	value = serverStats.CustomStats["someCounter"].(int)
	value++

	serverStats.CustomStats["someCounter"] = value
})
httpServer.Use(serverStats.Middleware)

httpServer.GET("/serverstats", serverStats.Handler)
