Description

It would be very helpful to me if the Camel API (Spring and Java) had the ability to expose the JMX service either using the host name or using IP address. At present release no option is given and the host name is always used.

This would mean a change to the logic in org.apache.camel.management.DefaultManagementAgent for determining JMX hostname in

protected void createMBeanServer()

method:

if (canAccessSystemProps) {
   try {
      hostName = InetAddress.getLocalHost().getHostName();
   } catch (UnknownHostException uhe) {
      LOG.info("Cannot determine localhost name. Using default: " +
         DEFAULT_REGISTRY_PORT, uhe);
      hostName = DEFAULT_HOST;
   }
} else {
   hostName = DEFAULT_HOST;
}

If the API passed down a request to use the IP then InetAddress.getLocalHost().getHostAddress() should be called rather than InetAddress.getLocalHost().getHostName().

The reason for wanting this is that my host has an underscore _ character in its name. A java.net.MalformedURLException: Bad URL path: exception is (correctly) thrown by javax.management.remote.JMXServiceURL when the looked up name is used to form the URL for the JMX service.

I know this is not a valid host name according to the various RFCs, but I have been unable to convince network administrators to change the host name. If I used the IP instead then validation would pass and the JMX service would be correctly exposed.

I would find it very helpful if the Camel API could expose an option to use JMX with host IP address as well as for the host name.

I would like to be able to configure something like this:

<jmxAgent id="camelJmxAgent" createConnector="true"
   registryPort="{{jmx.registry.port:1099}}" useIpAddress="true"  />

Thanks!
