Getting Started

To start using the Management Center:

  1. download the Hazelcast Management Center package

  2. start the Management Center service

  3. launch the Management Center user interface.

Downloading Management Center

Hazelcast Management Center is included in the Hazelcast IMDG download package. You can download it from the download page of Hazelcast’s website.

When a new Hazelcast IMDG version is released, it comes with a Management Center that is compatible with IMDG. There may be times when a new Management Center version is released before a new version of Hazelcast IMDG. In that case, you may download the new Management Center from its download page as a separate package.

Starting the Management Center Service

You have the following options to start the Management Center service:

  • Start Hazelcast Management Center from the command line.

  • Use the scripts that come with the download package.

  • Deploy the file hazelcast-management-center-4.2020.12.war on your Java application server/servlet container.

Using the Command Line

After you downloaded, extract the Hazelcast IMDG or Management Center package. The extracted directory, i.e., hazelcast-management-center-4.2020.12, contains the hazelcast-management-center-4.2020.12.jar file.

You can start this file directly from the command line using the following command:

java -jar hazelcast-management-center-4.2020.12.jar

The above command starts the Hazelcast Management Center service on the port 8080 with the root context path (http://localhost:8080).

In Management Center 4.0, the default context path changed from hazelcast-mancenter to the root context path.

You can use -Dhazelcast.mc.http.port and -Dhazelcast.mc.contextPath command line options to start Management Center on a different port and context path:

java -Dhazelcast.mc.http.port=8083 -Dhazelcast.mc.contextPath='hazelcast-mc' -jar hazelcast-management-center-4.2020.12.jar

The above command starts Management Center on port 8083 and context path hazelcast-mc. You can access it by opening http://localhost:8083/hazelcast-mc in your browser.

Then, you need to let Management Center know the Hazelcast IMDG member addresses as explained in the Connecting to the Clusters chapter.

For the options you can provide when starting with the command line, see the Configuring Management Center chapter. In that chapter, you can learn about topics including how to start with a license or extra classpath, how to configure the security, disk usage, update interval or logging.

Deploying to Application Server

Instead of starting at the command line, you can deploy the Management Center to your application server (Tomcat, Jetty, etc.).

Using Scripts in the Package

As another option, you can use the start.bat or start.sh scripts, which come with the download package in bin/ folder, to start the Management Center. You can find these scripts under the extracted directory.

Quick Launch

After the above steps are completed, let’s quickly open the Management Center user interface with the default settings.

Assuming that you have started your Hazelcast IMDG and Jet clusters each including a single member on your local machine (localhost) and started the Management Center service on http://localhost:8080, follow the below instructions:

  1. Go to http://localhost:8080 using your preferred browser.

  2. Select Dev Mode as the security provider, and click Save (note: this configuration is not recommended for production environments).

  3. Login with your newly created credentials, and "Manage Clusters" page appears.

  4. Click on the "Add Cluster Config" button to connect Management Center to your IMDG cluster:

    1. Click on the Save button after providing your IMDG cluster’s name and member address (localhost).

  5. Again, click on the "Add Cluster Config" button to connect Management Center to your Jet cluster:

    1. Click on the Save button after providing your Jet cluster’s name (use the default jet) and member address (localhost).

  6. On the "Manage Cluster" page, click on the Select button for a desired cluster to monitor it; the dashboard of your cluster appears as shown below:

Dashboard

Also see here and here for information on starting the IMDG and Jet clusters, respectively.

You also have the Dev Mode option for development or evaluation purposes that provides quick access to Management Center without requiring any security credentials. See the Dev Mode section for details.
