Error Connecting: java.net.BindException: Can't assign requested address

[Samuel Stanley]

Hi,

I am trying to send some custom metrics to Prometheus using the java client. Below is my code. However, when I run the sample I get the following error:

java.net.BindException: Can't assign requested address at sun.nio.ch.Net.bind0(Native Method) at sun.nio.ch.Net.bind(Net.java:433) at sun.nio.ch.Net.bind(Net.java:425) at sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:223) at sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java:74) at sun.net.httpserver.ServerImpl.<init>(ServerImpl.java:100) at sun.net.httpserver.HttpServerImpl.<init>(HttpServerImpl.java:50) at sun.net.httpserver.DefaultHttpServerProvider.createHttpServer(DefaultHttpServerProvider.java:35) at com.sun.net.httpserver.HttpServer.create(HttpServer.java:130) at io.prometheus.client.exporter.HTTPServer.<init>(HTTPServer.java:176) at io.prometheus.client.exporter.HTTPServer.<init>(HTTPServer.java:211) at com.test.promtheus.App.main(App.java:38)

When i try the URL on the browser it loads the dashboard correctly.

public class App {

 public static void main( String[] args ) { 

 System.out.println( "Hello World!" );

 final Counter counter =

Counter.build().namespace("java").name("my_counter").help("This is my counter").register(); 

 Thread bgThread = new Thread(new Runnable() { 

 @Override 

 public void run() { 

 while (true) { 

 try { 

 counter.inc(); 

 Thread.sleep(1000); 

 } catch (InterruptedException e) 

{

 e.printStackTrace(); 

 }

 }

 } 

 }); 

 bgThread.start();

 try 

{

 HTTPServer server = new HTTPServer("test.xyz.com",30000);

 } catch (IOException e) 

{

 e.printStackTrace();

 } 

 } 

}

Am i missing something?
