 # Expvar Receiver

 An Expvar Receiver scrapes metrics from [expvar](https://pkg.go.dev/expvar), 
 which exposes data in JSON format from an HTTP endpoint. The metrics are 
 extracted from the `expvar` variable [memstats](https://pkg.go.dev/runtime#MemStats), 
 which exposes various information about the Go runtime.
 
-> :construction: This receiver is in development and incomplete. It should not be used yet.
