SignalFx Middleware for Gin

Configuration: simply provide the SignalFx token and (optionally) the service name when configuring the middleware. The hostname will also get added to the metadata, along with the service name .

Super simple usage:

import ( github.com/tingold/gin-signalfx/middleware
         github.com/gin-gonic/gin
        )
g := gin.New()
g.Use(SignalFx(Config{SignalFXKey:"INSERT KEY HERE", ServiceName: "YOUR GIN SERVICE"}))
//start gin normally
...

Upon starting the server you should start to see metrics appear in your SignalFx dashboard

Metrics

All Gin specific metrics can be found by searching for gin.* in SignalFx

The following metrics will be reported:

• Counts for each of the HTTP verbs in the format of gin.request.{verb}
• Hits (e.g requests)
• Errors: response codes > 399
