You should also be able to inspect your connection without `ssh` and `netstat`. + +![Events page with connections](https://raw.githubusercontent.com/mwitkow/go-conntrack/images/events.png) + +## How to use? + +All of these examples can be found in [`example/server.go`](example/server.go): + +### Conntrack Dialer for HTTP DefaultClient + +Most often people use the default `http.DefaultClient` that uses `http.DefaultTransport`. The easiest way to make sure all your outbound connections monitored and trace is: + +```go +http.DefaultTransport.(*http.Transport).DialContext = conntrack.NewDialContextFunc( + conntrack.DialWithTracing(), + conntrack.DialWithDialer(&net.Dialer{ + Timeout: 30 * time.Second, + KeepAlive: 30 * time.Second, + }), +) +``` + +#### Dialer Name + +Tracked outbound connections are organised by *dialer name* (with `default` being default). The *dialer name* is used for monitoring (`dialer_name` label) and tracing (`net.ClientConn.` family). + +You can pass `conntrack.WithDialerName()` to `NewDialContextFunc` to set the name for the dialer. Moreover, you can set the *dialer name* per invocation of the dialer, by passing it in the `Context`. For example using the [`ctxhttp`](https://godoc.org/golang.org/x/net/context/ctxhttp) lib: + +```go +callCtx := conntrack.DialNameToContext(parentCtx, "google") +ctxhttp.Get(callCtx, http.DefaultClient, "https://www.google.com") +``` + +### Conntrack Listener for HTTP Server + +Tracked inbound connections are organised by *listener name* (with `default` being default). The *listener name* is used for monitoring (`listener_name` label) and tracing (`net.ServerConn.` family). For example, a simple `http.Server` can be instrumented like this: + +```go +listener, err := net.Listen("tcp", fmt.Sprintf(":%d", *port)) +listener = conntrack.NewListener(listener, + conntrack.TrackWithName("http"), + conntrack.TrackWithTracing(), + conntrack.TrackWithTcpKeepAlive(5 * time.Minutes)) +httpServer.Serve(listener) +``` + +Note, the `TrackWithTcpKeepAlive`. The default `http.ListenAndServe` adds a tcp keep alive wrapper to inbound TCP connections. `conntrack.NewListener` allows you to do that without another layer of wrapping. + +#### TLS server example + +The standard lobrary `http.ListenAndServerTLS` does a lot to bootstrap TLS connections, including supporting HTTP2 negotiation. Unfortunately, that is hard to do if you want to provide your own `net.Listener`. That's why this repo comes with `connhelpers` package, which takes care of configuring `tls.Config` for that use case. Here's an example of use: + +```go +listener, err := net.Listen("tcp", fmt.Sprintf(":%d", *port)) +listener = conntrack.NewListener(listener, + conntrack.TrackWithName("https"), + conntrack.TrackWithTracing(), + conntrack.TrackWithTcpKeepAlive(5 * time.Minutes)) +tlsConfig, err := connhelpers.TlsConfigForServerCerts(*tlsCertFilePath, *tlsKeyFilePath) +tlsConfig, err = connhelpers.TlsConfigWithHttp2Enabled(tlsConfig) +tlsListener := tls.NewListener(listener, tlsConfig) +httpServer.Serve(listener) +``` + +# Status + +This code is used by Improbable's HTTP frontending and proxying stack for debuging and monitoring of established user connections. + +Additional tooling will be added if needed, and contributions are welcome. + +#License + +`go-conntrack` is released under the Apache 2.0 license.
