Hawtio consists of 2 parts: an AngularJS applicaton and a Java backend, which proxies the communication between the frontend and Jolokia endpoints. The frontend has access to all JMX attributes and operations available in Java applications running locally and remotely.

Ways to run it:

The out of the box defaults try to do the right thing for most folks but if you want to configure things then please check out the configuration guide.

Running an executable JAR

You can startup Hawtio on your machine using the hawtio-app executable JAR.

Download hawtio-app.jar

Once you have downloaded it, just run this from the command line:

java -jar hawtio-app-x.y.z.jar

Note: If you launch Hawtio with Java 9+, add the specified modules to avoid errors on startup and allow attaching to other Java processes:

java --add-modules jdk.attach,java.xml.bind -jar hawtio-app-x.y.z.jar

The console should show you which URL to open, which by default is http://localhost:8080/hawtio.

To set a different port number, run:

java -jar hawtio-app-x.y.z.jar --port 8090

To see the full list of configuration options, run:

java -jar hawtio-app-x.y.z.jar --help

Running a Spring Boot app

Attaching the Hawtio console to your Spring Boot app is simple.

Set up

  1. Add io.hawt:hawtio-springboot to the dependencies in pom.xml:

  2. Enable the Hawtio and Jolokia endpoints by adding the following line in application.properties:


Now you should be able to run Hawtio in your Spring Boot app as follows:

mvn spring-boot:run

Opening http://localhost:8080/actuator/hawtio should show the Hawtio console.

If you'd prefer to not have the /actuator base path, then you can customize the Spring Boot management base path with the management.endpoints.web.base-path property:


You can also customize the path to the Hawtio endpoint by setting the management.endpoints.web.path-mapping.hawtio property:



There is a working Spring Boot example that shows Hawtio monitoring a sample web application which exposes information about Apache Camel routes, metrics, etc.

Hawtio Spring Boot example

A good MBean for real time values and charts is java.lang/OperatingSystem. Try looking at Camel routes. Notice that as you change selections in the tree the list of tabs available changes dynamically based on the content.

Deploying on a Servlet container

If you use Tomcat or Jetty, you can deploy the Hawtio WAR file.

Download hawtio-default.war

Please read the configuration guide to see how to configure the console, in particular security.

Deploying on an application server

If you don't use the WildFly application server, use one of the options from the Servlet container section to download Hawtio.

If you do use WildFly, download hawtio-wildfly.war.

To enable security, you'll need to set up configuration like this:


    <property name="hawtio.authenticationEnabled" value="true" />
    <property name="hawtio.realm" value="jboss-web-policy" />
    <property name="hawtio.role" value="admin" />

If you experience problems with security, you'll need to disable security in Hawtio. For WildFly, you can set the hawtio.authenticationEnabled system property in standalone/configuration/standalone.xml:


    <property name="hawtio.authenticationEnabled" value="false" />

Deploying on Apache Karaf

Hawtio provides the following features for Apache Karaf:

Feature Description
hawtio-core Installs the core Hawtio war file with minimal extensions
hawtio-rbac Installs the Hawtio RBAC enabler bundles
hawtio-log Installs the Hawtio logging backend MBeans
hawtio Installs the main Hawtio web console

If you are using Apache Karaf 4.x:

feature:repo-add hawtio <version>
feature:install hawtio

This will install all the features listed above. The Hawtio console can then be viewed at http://localhost:8181/hawtio.

Karaf versions prior to 4.x are not supported.

If you use an HTTP proxy

If you are behind an HTTP proxy, you'll need to enable HTTP proxy support in WildFly / Karaf to be able to download Hawtio from the central maven repository.

There are a few articles about this which may help. Here are the steps:

Edit the etc/org.ops4j.pax.url.mvn.cfg file and make sure the following line is uncommented:


You may also want org.ops4j.pax.url.mvn.settings to point to your Maven settings.xml file. NOTE use / in the path, not .

org.ops4j.pax.url.mvn.settings=C:/Program Files/MyStuff/apache-maven-3.0.5/conf/settings.xml

WildFly / Karaf will then use your Maven HTTP proxy settings from your ~/.m2/settings.xml to connect to the maven repositories listed in etc/org.ops4j.pax.url.mvn.cfg to download artifacts.

Using Hawtio embedded in a Java application

If you do not use a servlet container or application server and wish to embed Hawtio inside your Java application, try the following:

Add the following to your pom.xml:


Then in your application run the following code:

import io.hawt.embedded.Main;

Main main = new Main();

If you wish to do anything fancy it should be easy to override the Main class to find the hawtio-war.war in whatever place you wish to locate it (such as your local maven repo or download it from some server etc).

Depending on the war you are loading, you may also need to turn off authentication before running the embedded hawtio so that it can be accessible in an unauthenticated environment:

System.setProperty("hawtio.authenticationEnabled", "false");
